I'm sure there's gotta be something new here, but what the title and intro describe could apply to induction motors, which date back to the 19th century. That makes the whole thing sound rather silly.
- adrian_b 5y agoWhat is new is that it has a high efficiency similar to the permanent magnet motors, i.e. a higher efficiency than induction motors. The reason for the high efficiency is because the motor seems to be some kind of synchronous motor, where the rotor is not supplied by wearable brushes but by a contactless transformer and a rectifier. Besides the permanent-magnet motors and the induction motors, there are 2 other kinds of electrical motors without supply contacts on the rotor: variable-reluctance motors and hysteresis motors. However these other 2 share the disadvantage of the induction motors of having a lower efficiency. The highest efficiency with no contacts to the rotor can be reached with either permanent-magnet motors or with designs similar to this Mahle motor.
