YRKS560-8 Motor Specs, Dimensions & Price | Xi'an XIMA

YRKS560-8 is a high-performance HV Wound-rotor Water-cooled Motor built by the manufacturer, rated approx. 740 kW, voltage 6kV / 10kV, synchronous speed 750 r/min, protection IP54, efficiency IE3. This guide covers model meaning, specifications, applications and ordering.

1. What YRKS560-8 means: series ≠ model

Many buyers treat “YRKS” 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 YRKS560-8:

• YRKS — series code, HV Wound-rotor Water-cooled Motor;
• 560 — frame size (center height in mm);
• -8 — pole count, 8 poles → synchronous speed 750 r/min.

Only YRKS560-8 is the unique, orderable model; “YRKS” alone cannot pin down the spec.

2. Key specifications

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

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 “YRKS” and YRKS560-8?

A: “YRKS” is only the HV Wound-rotor Water-cooled Motor family code; YRKS560-8 adds frame and poles and is the orderable spec.

Q: What is the rated power of YRKS560-8?

A: Estimated approx. 740 kW (6kV / 10kV); final value per datasheet and order confirmation.

Q: Is frame 560 large? Any mounting notes?

A: 560 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 matter?

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

Q: How is YRKS560-8 cooled?

A: Cooling IC81W; 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 YRKS560-8?

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