ABSTRACT:
In the motor disclosed, five stator windings are distributed on u groups each having five main poles and coacts with a permanent magnet rotor. Each pole has n+1 pole teeth. The stator windings are connected in series or parallel to form five connecting points. A control switches five switches having an armature connected to a connecting point between a positive and negative potential so as simultaneously to energize the windings as required. The control then shifts the short-circuited condition to other windings in cyclical sequence while energizing the remaining four windings at any time. The pole divisions exhibit the relationships
