Product Description

WST Series IE5/IE4 Permanent Magnet Synchronous Motors

1. General introduction

General introduction

 

The WST Series permanent magnet synchronous motor is self-developed by Wonder Electric, which achieves energy efficiency levels of IE5 and IE4 according to IEC 60034.

The WST motors are supplied with build-in permanent magnetic steel produced from rare earth PM material (NdFeB) which is with high coercive force and hypertonic magnetic induction force. The motor guarantees high performance while offering higher power density. Even in the case of overload, the motor can also show excellent electrical characteristics.

WST Series features series of advantages such as superior energy-saving effect, low temperature rise, precise and smart control, compact structure, etc. The motors are widely used where speed variation, high efficiency and reduced volume are mandatory.
