Synchronous motors (DCH)

With the new DCH series of motors, the engineers at ATE have managed to translate motorsport technology into series production. Thanks to a special arrangement of magnets, it has been possible to guide the magnetic flux within the magnet. The magnetic back iron in the rotor, which is otherwise essential, can be limited to a minimum as a result. This results in many advantages: Ideal field weakening properties increase the spread of rotational speeds without reducing the peak torque. In many applications, it is possible to do without an additional series reactor and a voltage protection module (VPM). Increasing the shaft diameter offers the user increased design freedom for the bearings and improves the shaft dynamics. As a result, the new series is a perfect addition to the portfolio of ATE.

Advantages of synchronous motors

- High power density
- High power factor
- Larger shaft diameter as the DC series
- Highest speed range
- Low inertia
- Good field weakening features
