Motor drive operation mechanism of High-Voltage Circuit Breaker(HVCB) need permanent magnet synchronous motor(PMSM) with high-dynamic response. Reducing the rotor inertia of PMSM is one technique to realize high dynamic response of the motor. By digging holes in the rotor, the inertia can be reduced. The influence of shape, position and size of inertia-reducing holes on the performance of PMSM is...
In order to improve the operation flexibility and reliability of high-voltage circuit breakers (HVCBs) and to realize the full control capability during the opening and closing operations, a new type of motor-drive operating mechanism is investigated in this paper. In this operating mechanism, the travel of the moving contact of HVCB is precisely controlled by controlling the motion of the permanent-magnet...
