Your benefits
- 2 speeds in one motor,
allow you to reduce the motion sequences in plants and machines with two or four times the motor speed.
Properties
- Simple winding changeover switching gives you two motor speeds
- Pole-changing motors are a simple and economic option for applications that need “only” 2 speeds
- Pole-changing motors are not subject to globally applicable efficiency standards, even if only one of the two speeds is continually in use
- A wide variety of additional features in the SEW‑EURODRIVE modular motor system and various speed ratios (1:2 and 1:4) offer you many potential uses
- We develop pole-changing motors ourselves according to our own proven modular system and manufacture them according to our own quality standards, even in our series production.
Technical data for example 400 V / line frequency 50 Hz
