Single-phase motor

A single phase motor includes a rotor including magnetic poles and a stator comprising a stator core and a winding wound on the stator core. The stator core includes a plurality of stator teeth each including a tooth body and a tooth end formed at an end of the tooth body, the tooth end comprising first and second arcuate regions facing the rotor. When the winding is not energized, a first magnetic coupling between said first arcuate region and a selected magnetic pole of said rotor is greater than a second magnetic coupling between said second arcuate region and the selected magnetic pole, said first arcuate region being offset from a selected tooth body in such a way as to enable movement of said rotor to initiate in either of two opposite directions relative to said selected tooth body upon energizing the winding.

Electric drive system

The heat pipes 9a provided here in the grooves 9 of the motor side conduct heat to the end of the output shaft 2 and the heat pipes 10a in the grooves 10 of the housing of the power supply to the opposite end. A flow of heat to axially opposing ends is thus produced that always travels away from the power electronics that are arranged approximately in the center of the system.
