How To Choose Electric Motor

The application of motor control in various industries is very wide, so the trend is different. However, for all industries, the most recent driving force is efficiency. The design of the motor and the design and control of the inverter are constantly improved.

Removing or at least reducing the magnetic components of the synchronous motor is also the focus of attention. The use of synchronous reluctance motor (not confused with switched reluctance motor) can achieve this goal, which is basically a permanent magnet synchronous motor (PMSM) without magnetic components. Because of the lack of magnetic components, it is difficult to control it. The advantage is that the cost is reduced and the efficiency in the full load range is increased.
