YE4280-6 efficiency & maintenance — IE4 Super-premium-efficiency Motor by Manufacturer

YE4280-6 is a high-performance IE4 Super-premium-efficiency Motor built by the manufacturer, rated approx. 75 kW, voltage 380V / 660V, synchronous speed 1000 r/min, protection IP55, efficiency IE4（GB 30254-2024）. This guide covers model meaning, specifications, applications and ordering.

1. What YE4280-6 means: series ≠ model

Many buyers treat “YE4” as a full model — a common mistake. The series code is only a product family; a complete motor model must include the frame size and pole count. For YE4280-6:

• YE4 — series code, IE4 Super-premium-efficiency Motor;
• 280 — frame size (center height in mm);
• -6 — pole count, 6 poles → synchronous speed 1000 r/min.

Only YE4280-6 is the unique, orderable model; “YE4” alone cannot pin down the spec.

6. Standards

• GB 18613-2020
• GB 30254-2024

7. Ordering notes

• State full model, power, voltage, speed/poles, mounting (IMB3/B5/V1) and protection/Ex level.
• Specify environment (temp, altitude, humidity, medium) and starting method (DOL/VFD/soft-start).
• Request special shaft, dual shaft, tachogenerator, encoder or brake at order time.
• Confirm cooling (IC411/IC416/IC611/IC81W) and matching cooler / inverter brand.
• Allow 10–15% power margin; confirm lead time, warranty and site commissioning scope.

8. FAQ

Q: What is the difference between “YE4” and YE4280-6?

A: “YE4” is only the IE4 Super-premium-efficiency Motor family code; YE4280-6 adds frame and poles and is the orderable spec.

Q: What is the rated power of YE4280-6?

A: Estimated approx. 75 kW (380V / 660V); final value per datasheet and order confirmation.

Q: Is frame 280 large? Any mounting notes?

A: 280 mm is a medium-large frame; bolt pattern per IMB3, foundation must be leveled, on-site guidance recommended.

Q: What is the protection / Ex level?

A: Protection IP55; for hazardous areas confirm the Ex mark and gas group.

Q: Why does efficiency IE4（GB 30254-2024） matter?

A: Higher efficiency cuts running cost and heat, ideal for continuous duty with short payback.

Q: How is YE4280-6 cooled?

A: Cooling IC411; keep cooling water/air path clear under full load.

Q: Can it be customized?

A: Yes — voltage, speed, shaft, mounting, sensors and coating; state requirements at order.

Q: Where to get quote and datasheet for YE4280-6?
