Product Overview<\/h2>\n

The YS series small-power three phase motor<\/b> uses a die-cast aluminum enclosure to achieve a lighter, more thermally efficient package than conventional cast-iron alternatives. Manufactured in accordance with the Chinese national standard JB\/T1009, this motor line covers output ratings from 0.12 kW to 4 kW with frame sizes that fit directly onto conveyors, blowers, small pumps, and a wide variety of food-processing and textile machinery. The design carries Class B or Class F insulation (depending on the model variant), combined with an IP54 dust-and-splash-proof enclosure and a totally enclosed fan-cooled (TEFC) construction.<\/p>\n

\"YS<\/p>\n

For Korean manufacturers looking to replace aging single-brand motor fleets with a more affordable yet reliable option, the YS series offers immediate compatibility with IEC-standard mounting arrangements. The aluminum body weighs substantially less than an equivalent iron-frame motor, which simplifies handling during installation and reduces structural load on machine frames. Applications range from bakery dough mixers and packaging conveyors to centrifugal fans in ventilation ducting \u2014 anywhere a compact, low-vibration electric motor<\/b> in the fractional-to-small-kilowatt range is needed.<\/p>\n

Every unit ships tested to IEC 60034 performance thresholds, and our quality management system holds ISO 9001 and CE certification. Spare parts \u2014 bearings, fan covers, terminal blocks \u2014 are stocked at our Korean distribution warehouse, so downtime stays short even when unexpected failures occur.<\/p>\n

Core Advantages<\/h2>\n

The YS aluminum series stands out from general-purpose iron-frame motors in several measurable ways. Each advantage below addresses a real concern that procurement teams and maintenance engineers face when specifying small-power drives.<\/p>\n

\"YS<\/p>\n

\n
\n

\u2699 Lightweight Aluminum Frame<\/p>\n

Die-cast aluminum reduces motor weight by roughly 30 % compared to a same-rated cast-iron unit. On machines where multiple small motors are mounted on a moving carriage or overhead gantry, this weight saving translates directly into lower structural costs and easier manual handling during maintenance swaps.<\/p>\n<\/div>\n

\n

\u26a1 Superior Heat Dissipation<\/p>\n

Aluminum has a thermal conductivity about three times higher than gray cast iron. The YS frame sheds heat faster, which helps keep winding temperatures well within the Class B\/F limit and contributes to a longer insulation life. In tightly enclosed machinery compartments, this thermal advantage becomes even more important.<\/p>\n<\/div>\n

\n

\ud83d\udd28 Easy Drop-In Installation<\/p>\n

Shaft dimensions, foot-mounting hole patterns, and flange interfaces follow IEC 60072 standards. The motor bolts into position using the same holes and alignment dowels as any IEC-compliant motor of the same frame size, so no bracket modifications or adapter plates are needed.<\/p>\n<\/div>\n

\n

\ud83d\udd08 Low Noise Operation<\/p>\n

The precision-machined rotor and optimized fan blade geometry keep airborne noise below 65 dB(A) on most frame sizes, making the YS a practical choice for food production halls and hospital equipment rooms where noise limits apply. Vibration levels meet IEC 60034-14 Grade A.<\/p>\n<\/div>\n

\n

\ud83d\udcb0 Competitive Pricing<\/p>\n

Factory-direct pricing with no distributor markup means the YS series typically costs 35 % to 50 % less than equivalent imported small-power motors from European or Japanese brands. Combined with local spare-part stocking in Korea, total cost of ownership stays low over the full service life.<\/p>\n<\/div>\n<\/div>\n

<\/p>\n

Application Scenarios for Small-Power AC Motors<\/h2>\n

The YS series finds use across a remarkably broad set of industries because its power range, physical size, and environmental rating match the requirements of many general-purpose machine designs. Below are five typical use cases with notes on why this particular motor suits each environment.<\/p>\n

Food Processing Equipment<\/h3>\n

Bakeries, noodle factories, and ready-meal production lines depend on small motors for dough mixers, conveyor belts, and filling machines. The aluminum housing resists corrosion from washdown chemicals better than bare cast iron, and the smooth external surfaces are easier to wipe clean during sanitation shifts. A 0.75 kW YS motor driving a tabletop belt conveyor, for instance, provides exactly the torque profile needed for gentle product handling at walking pace.<\/p>\n

Textile Machinery<\/h3>\n

Spinning frames, winding machines, and loom auxiliaries call for motors that run quietly and vibrate as little as possible \u2014 fabric quality suffers when excessive motor vibration propagates through the machine frame. The YS series meets this requirement, and the lightweight body keeps total spindle-head weight down on multi-station textile machines where dozens of small motors may be mounted side by side.<\/p>\n

\"YS<\/p>\n

Ventilation Fans and Blowers<\/h3>\n

Commercial HVAC systems, kitchen exhaust hoods, and industrial dust-collection units all use small AC gear motor<\/b> drives in the 0.37 kW to 4 kW range. The high starting torque of the YS series ensures the fan impeller accelerates quickly to operating speed, even when the duct system is partially restricted by damper positions. The self-cooled IC0141 design tolerates the elevated ambient temperatures often found inside fan housings.<\/p>\n

Packaging Machinery<\/h3>\n

Carton erectors, shrink-wrap tunnels, and labeling stations need responsive, compact motors that start and stop frequently without overheating. The excellent thermal conductivity of the aluminum frame gives the YS a practical edge in these intermittent-duty situations, because heat generated during each start cycle dissipates faster between cycles. For machines that run multiple shifts, this heat management directly extends bearing and winding life.<\/p>\n

Small Pumps and Compressors<\/h3>\n

Coolant circulation pumps on CNC machine tools, lubrication pumps on hydraulic presses, and small air compressors for pneumatic clamps often need a motor in the 0.25 kW to 1.5 kW bracket. The YS delivers enough starting torque to overcome the initial compression load, and its continuous S1 duty rating means it can run around the clock without scheduled cooldown periods.<\/p>\n

Structure and Material Craftsmanship<\/h2>\n

Understanding what goes into the motor helps buyers assess whether its construction matches the demands of their specific environment. The YS series is built around a few key material and manufacturing choices that prioritize long-term reliability in the small-power segment.<\/p>\n

The stator frame and end shields are die-cast from ADC12-grade aluminum alloy, a material widely used in automotive and industrial castings for its balance of strength, machinability, and corrosion resistance. After casting, the housing surfaces are precision-bored on CNC lathes to ensure concentricity between the bearing seats and the stator bore. This dimensional accuracy reduces air-gap eccentricity, which in turn minimizes magnetic noise and unbalanced magnetic pull on the rotor.<\/p>\n

The stator core is built from 0.5 mm cold-rolled silicon steel laminations, stamped and stacked under controlled pressure to keep core losses low. Windings are machine-inserted using class B or class F magnet wire, depending on the insulation grade ordered. After winding, each stator assembly goes through a vacuum-pressure impregnation (VPI) cycle with solvent-free polyester resin. This process fills air pockets around the conductors, improving thermal conductivity from copper to iron and locking the windings against vibration-induced movement. The rotor is a standard die-cast aluminum squirrel cage. Rotor bars and end rings are cast as a single piece within the lamination stack, then the entire assembly is dynamically balanced to ISO 21940-11 Grade G2.5. Bearings are deep-groove ball type (6200 or 6300 series depending on frame), pre-lubricated with a polyurea-based grease rated for at least 20 000 hours of continuous duty at rated load.<\/p>\n

Related and Complementary Products<\/h2>\n

\"ac-gear-motor-related-products\"<\/p>\n

Small-power motors seldom operate alone. They connect to the driven machine through couplings, gearboxes, or chain-and-sprocket sets, and each of these transmission elements plays a role in the overall performance and service life of the drive train.<\/p>\n

When the YS motor speed does not match the required machine speed, a compact worm gear reducer<\/a> provides a convenient single-stage reduction with ratios from 5:1 up to 60:1. The right-angle shaft arrangement of a worm unit also saves space in cramped machine enclosures. For applications that demand higher efficiency and lower heat generation than a worm set can deliver, a planetary gearbox<\/a> is the better option \u2014 it keeps the input and output shafts coaxial and achieves mechanical efficiencies above 95 % per stage.<\/p>\n

Chain drives remain a popular choice for conveyor and packaging machinery because they tolerate moderate misalignment and absorb shock loads without slipping. Industrial roller chain, stainless-steel chain for washdown environments, and matched sprocket and chain<\/a> sets are available through our partner catalog. Flexible jaw couplings and beam couplings round out the product offering for direct-coupled installations. Visit the ac gear motor for sale<\/a> homepage to explore the full catalog.<\/p>\n

Frequently Asked Questions<\/h2>\n

What is the weight difference between the YS aluminum motor and a standard cast-iron motor of the same rating?<\/b>
\nOn average, the YS weighs about 30 % less. For a 1.5 kW frame, the difference is roughly 5 to 6 kg, which matters when workers lift motors into position by hand on elevated machine frames.<\/p>\n

Can the YS series motor be used with a frequency inverter for variable speed control?<\/b>
\nYes, but with a caveat. The YS uses a shaft-mounted cooling fan (IC0141), so airflow decreases at low speed. If you plan to run below 25 Hz for extended periods under load, you should install an external forced-ventilation kit or consider the YVF2 series, which comes with an independent cooling fan designed specifically for AC gear motor with speed control<\/b> duty.<\/p>\n

Is the aluminum housing prone to corrosion in humid environments?<\/b>
\nThe ADC12 aluminum alloy forms a natural oxide layer that provides moderate corrosion protection. For outdoor or high-humidity installations, we apply an optional powder-coat finish (RAL 7035 light gray or custom color). This coating passes a 500-hour salt-spray test per ISO 9227.<\/p>\n

How do I verify the correct replacement model for an existing motor on my machine?<\/b>
\nSend us a photo of the original motor nameplate plus the shaft height, output power, and supply voltage. Our engineering team will cross-reference the data and confirm the correct YS model number, usually within the same business day.<\/p>\n

What maintenance schedule should I follow for the YS motor?<\/b>
\nCheck bearing noise and vibration every 2 000 hours. Clean the external fan cover and air intake grille every 1 000 hours in dusty environments, or every 3 000 hours in clean workshops. For motors with greaseable bearings, replenish grease every 5 000 hours or annually. Sealed bearings (used on smaller frame sizes) do not require re-greasing during their rated service life of approximately 20 000 hours.<\/p>\n

Do you supply 220 V single-phase versions of the YS motor?<\/b>
\nThe YS series is a three-phase product line. For single-phase 220 V requirements, please refer to our JY series capacitor-start induction motor<\/b> or the YC series capacitor-start-and-run motor, both available through our types of gear motor<\/a> catalog.<\/p>\n

What is the minimum order quantity for shipment to Korea?<\/b>
\nThere is no minimum. We accept single-unit orders and ship via express freight. For larger quantities (palletized shipments of 20 units or more), we offer volume-based discounts and consolidated ocean freight to Busan and Incheon ports.<\/p>\n

Can the terminal box be rotated for cable entry from a different direction?<\/b>
\nYes. The terminal box on the YS motor can be repositioned in 90-degree increments by loosening four mounting screws. This allows top, left, or right cable entry to suit your machine layout. The adjustment can be done on site without special tools.<\/p>\n

Motor performance is consistent; no complaints from the maintenance team after nine months of 24\/7 operation.”<\/p>\n

\n

Oh Sung-min, Quality Control Manager, Gyeonggi-do<\/b> (early 2025)
\n“We run a food-grade facility, so everything gets audited. The smooth aluminum finish on the YS motors is much easier to keep clean than the ribbed cast-iron bodies we had before. The CE certification documents came with the shipment, which saved time during our last external audit.”<\/p>\n

\n

Han Woo-jin, Workshop Foreman, Changwon<\/b> (mid 2025)
\n“Bought a single YS-8024 (1.5 kW) to test on a coolant pump. The pump is in a tight enclosure and the old motor used to trip on thermal overload every summer. The aluminum motor runs about 8 degrees cooler on the same pump, same ambient. Ordered four more for the other machining centers.”<\/p>\n

\n

Seo Eun-bi, Facility Engineer, Gwangju<\/b> (late 2024)
\n“Quick response from the sales team when I needed a dimensional drawing for our new dryer frame. They sent a DXF file the same afternoon. Motor arrived on schedule and the bolt pattern matched the drawing exactly. Straightforward experience.”<\/p>\n

\n

Jang Seung-woo, Production Supervisor, Busan<\/b> (early 2025)
\n“I manage a small textile workshop. We replaced two 0.37 kW motors on winding machines. The weight difference is real \u2014 my technician installed both by himself in under an hour. The motors have been running two shifts a day for four months, bearings still feel smooth, no abnormal heat.”<\/p>\n
