You’re looking at roughly 85-87% efficieny at full load with the 4-pole configuration, which is where most industrial buyers land, and it’s a noticeable jump from less efficient designs—the IE4 class really means you’re saving on power draw over a 10-year run.
It’s a three-phase asynchronous motor with auto-induction voltage-reduced starting, so the startup current doesn’t slam the line, and we usually stock the 380V/415V versions for 50Hz and 60Hz both, though you can customize voltage if you’re running odd mains. Protection is IP55, meaning it handles dust and hose-downs fine, and insulation class F is standard for continuous duty (S1, so it runs non-stop if you need it). Noise is capped at 75dB(A) or less, and vibration stays under 2.8mm/s—tight enough for most conveyor or pump setups. Ambient temperature range is -15°C to +40°C, but it’s not suited for altitudes above 1000m without derating, which buyers sometimes miss.
People use these on compressors, fans, and mixers mainly—pretty much any industrial machine that needs reliable continuous torque, but they’re not ideal for frequent reversing or heavy shock loads because teh auto-induction start is softer than a direct-on-line setup. The pole options (2P, 4P, 6P, 8P) give you speed flexibility: 2P is fast (roughly 3000 rpm at 50Hz), 8P is slower (about 750 rpm), so match it to your driven load’s RPM range.
Certifications are ISO9001 and CCC, and our company provide COAs with every shipment—some batches have had slightly higher vibration on the 2P variants, but it’s still within spec, and we recommend checking the bearing grease type if you’re in high-humidity environments. Frame sizes go form B15 up to B65, and the deep groove ball bearings are good for general duty, but they’re not sealed for extreme debris.
MOQ is usually 10 units or so, and we ship within 20-30 days typically, but confirm lead time for non-standard voltages (like 200V or 690V). Packaing is plywood crates with foam inserts—these motors are heavy, so we strap them well. You’ll want to specify pole count and frame size when ordering, as stock varies.
The YE4-6P comes in 2P, 4P, 6P, and 8P pole configurations. More poles mean lower synchronous speed — for example, a 2P motor runs around 3000 rpm at 50Hz, while an 8P runs around 750 rpm.
Yes, voltage is customizable — just let us know what you need. We can adjust it to match your local supply, as long as it's within reasonable range for the motor design.
It's certified ISO9001 and CCC. That covers quality management and Chinese mandatory product compliance, so it's good for most industrial applications.
We typically require a minimum order of 10 units for standard specs. Custom versions might have a higher MOQ, so get in touch for exact numbers.
It's rated IP55, meaning it's dust-protected and can handle water jets. It works in ambient temperatures from -15°C to +40°C, and at altitudes up to 1000m.
