YPT3-355S1-12 75 kW 10000V Rated Current 5.5A Dimensions

YPT3-355S1-12 is a high-performance Induction Motor built by Xi'an XIMA Electric (Group) Co., Ltd., rated 75 kW, voltage 10000V, rated current approx. 5.5 A, protection IP55, efficiency 90.8%. Based on real sample data, this guide covers model meaning, specifications, selection and FAQ.

1. What YPT3-355S1-12 means: series ≠ model

Many buyers treat “YPT” 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 YPT3-355S1-12:

• YPT — series code, Induction Motor;
• 355 — frame size (center height in mm);
• poles / spec — corresponds to synchronous speed 500 r/min.

Only YPT3-355S1-12 is the unique, orderable model; “YPT” 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

• Meets the applicable national efficiency class, cutting operating electricity cost.
• Optimized EM design with low-loss lamination raises efficiency and power factor.
• Compact IP55 construction for pumps, fans and compressors.
• Multiple mounting (B3/B5/B35/V1) with strong interchangeability.
• Premium bearings and seals extend maintenance interval on automation lines.

5. Typical industries

6. Standards

• GB 18613-2020
• IEC 60034-30-1

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 “YPT” and YPT3-355S1-12?

A: “YPT” is only the Induction Motor family code; YPT3-355S1-12 adds frame and spec code and is the orderable model.

Q: What are the rated power and current of YPT3-355S1-12?

A: Sample rated power approx. 75 kW, voltage 10000V, rated current approx. 5.5 A; final per datasheet and order confirmation.

Q: Is frame 355 large? Any mounting notes?

A: 355 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 90.8% matter?

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

Q: How is YPT3-355S1-12 cooled?

A: Cooling IC411; 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 YPT3-355S1-12?
