The prototype of limited angle permanent magnet motor and the performance testing are researched based on the mechanical property requirements of 40.5kV vacuum circuit breaker. The system of performance testing is accomplished according to the permanent magnet motor and circuit breaker. Sensors with high precision are selected, and the circuit and method of testing are designed. The mechanical characteristics...
The mechanical properties monitoring system of permanent magnet motor operating mechanism is developed base on the indoor 40.5kV vacuum circuit breaker in order to improve the security and reliability of power system. The high-precision linear displacement sensor is used to measure the stroke of moving contact, the angular sensor is employed to test the rotation angle of motor, and the hall current...
The permanent magnet motor, which is applied in the high voltage disconnecting switch, used for reducing the VFTO in the operation of disconnecting switch and enhancing the operating performance, and therefore achieves the opening and closing operation and brings quicker response ability and control performance, is presented. The structure and the parameters of the motor are designed according to...
Robust L2 control is a controller with fixed structure and parameter. It also satisfies performance requirement under the bad uncertainty, which is a salient features for Robust L2 control. The mathematical model of Brushless Direct Circuit Linear Motor (BLDCLM) is nonlinear, so introduction nonlinear control can restrain disturbance and track the input signal accurately. Then according to positioning...
