Abstract:
A magnet motor has a stator formed from a laminated core provided with windings to form phases and a rotor provided with magnets distributed angularly around at least one section of the rotor and pivotably received in the housing of the stator. The stator has a length greater than a length of said section of the rotor and the rotor is provided with at least one ring made from magnetic material that adjoins said section and is received in the housing of the stator. A drive device having a plurality of motors and a method for producing such a motor are also provided.
