YKS500 2 kW 380V Rated Current 3.6A Efficiency Class

YKS500 is a high-performance HV Air-Water Cooled Motor built by Xi'an XIMA Electric (Group) Co., Ltd., rated 2 kW, voltage 380V, rated current approx. 3.6 A, protection IP54, efficiency IE3 / IE4. Based on real sample data, this guide covers model meaning, specifications, selection and FAQ.

1. What YKS500 means: series ≠ model

Many buyers treat “YKS” 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/spec code. For YKS500:

• YKS — series code, HV Air-Water Cooled Motor;
• 500 — frame size (center height in mm);
• poles / spec — corresponds to synchronous speed 1500 r/min.

Only YKS500 is the unique, orderable model; “YKS” alone cannot pin down the spec.

2. Key specifications (real sample)

Note: above are library sample parameters; final values per XIMA datasheet and order confirmation.

3. Technical features

• VPI vacuum pressure impregnation with Class F insulation (Class B rise) for excellent dielectric strength.
• SKF/FAG bearings with vibration below GB 10068 limits for smooth running.
• Air-water / air-air cooling with large thermal margin for continuous S1 duty.
• Rigid welded steel frame, low noise, IP54 for dusty / humid environments.
• Optional Pt100 sensors, space heater and smart terminal box for condition monitoring.

6. Standards

• GB 755
• GB 30254-2024
• IEC 60034-1

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 “YKS” and YKS500?

A: “YKS” is only the HV Air-Water Cooled Motor family code; YKS500 adds frame and spec code and is the orderable model.

Q: What are the rated power and current of YKS500?

A: Sample rated power approx. 2 kW, voltage 380V, rated current approx. 3.6 A; final per datasheet and order confirmation.

Q: Is frame 500 large? Any mounting notes?

A: 500 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 IP54; for hazardous areas confirm the Ex mark and gas group.

Q: Why does efficiency IE3 / IE4 matter?

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

Q: How is YKS500 cooled?

A: Cooling IC81W; keep cooling medium/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 YKS500?

A: Visit www.xadjw.com or contact Xi’an XIMA sales engineers for selection and quote.
