| Abstract: | During the research of 11kW rare earth permanent magnet brushless DC motor starting process,the control strategy by slope voltage was used to reduce the higher current. It was got that parameters influencing on current and the relationship between current peak value and slope control time in starting process by slope voltage, and the definition of motor starting efficiency was proposed. The results of simulation demonstrated that the control strategy of slope voltage was efficient to control the current of starting process, and to realize the motor starting immediately. |
| Keywords: | rare earth permanent magnet brushless DC motor starting process stating eurent slope voltage |
