ABSTRACT:
A hybrid synchronous electric machine driven by the transverse magnetic flux has a rotor and a stator, the rotor armature has a massive cogged iron rings (12) in close vicinity of active parts of the motor, and cogged iron rings (14, 15) as component parts of the rotor are provided with cross-cut insulating gaps. Eddy current losses are low because eddy currents in cogged iron rings are impeded by cross-cut insulating gaps therein. Eddy currents in all passive parts of the motor (rotor armature (11), stator armature (1), ball bearing (9) and the like) are negligible since the current induced in the copper ring (12) neutralizes all the dissipated magnetic flux outside the active area of the motor. A hybrid synchronous electric machine which has low eddy current losses and high energy efficiency can be realized.
