Patent CA-2244546-A1 (CA)
Inventor: BLUM DIETER W
IPC: H02K11/04
Filed: 1998-08-05
Abstract: A dynamo-electric machine which can function as a motor or a generator. The machine comprises a stator and an armature. Switching of the armature coils is accomplished by means of a switching control assembly which is mounted to and rotates with the armature. In operation as a motor, direct current is suplied through brushes to slip rings that rotate with the armature and the DC current supplied is first passed through switch means in the control assembly to deliver the current in properly timed relationship with respect to the rotation of the rotor. This provides greater versatility in the operation of the motor/generator and eliminates many of the problems related to the use of convention brush commutation used in present day DC motors and generators and allows optimization of the motor with respect to factors denigrating from earlier performance deficiencies.
