4 Pole Motors (1500 RPM) Manufacturers

4 Pole Motors (1500 RPM)

-- Steady & Reliable Manufacturer --

Introduction

**6-Pole motors** are designed for applications that require a lower operating speed and often higher starting torque compared to the standard 4-Pole motor. For a 50Hz supply, the synchronous speed is $1000 \text{ RPM}$ (running speed typically around $980 \text{ RPM}$). This speed is excellent for driving large fans, mixers, and crushers where the load is heavy and sudden starts are required. Our **6 Pole Motors** minimize component wear due to the slower rotational speed while delivering robust, reliable power and being available in all explosion-proof and high-efficiency variants.

Why choose us?

Application Industries

  • Heavy-Duty Mixers and Agitators: Ideal speed for blending high-viscosity fluids and slurries.

  • Large Process Fans: Motors for induced draft (ID) or primary ventilation fans.

  • Crushers and Ball Mills: High-torque requirements for starting heavy, static loads.

  • Reciprocating Compressors: Used where a slower, more deliberate speed profile is necessary.

Frequently Asked Questions

Frequently Asked Questions

  • Q: When should I choose a 6-Pole over a 4-Pole motor?
  • A: Choose 6-Pole when the driven equipment requires a nominal $1000 \text{ RPM}$, needs high breakaway torque, or if lower vibration levels are a priority.
  • Q: Are 6-Pole motors more expensive than 4-Pole?
  • A: Generally, yes. They require a larger frame size and more complex windings to achieve the same power output at a slower speed.
  • Q: Do you offer 8-Pole or 10-Pole motors?
  • A: Yes. For speeds slower than $1000 \text{ RPM}$, we custom-engineer 8-Pole ($750 \text{ RPM}$) and 10-Pole ($600 \text{ RPM}$) motors for specific requirements.
