| 发明名称 | Control of a brushless motor | ||
| 摘要 | A method of controlling a brushless motor that includes exciting a winding of the motor with a voltage, and freewheeling the winding when current in the winding exceeds a threshold or after the winding has been excited for a timeout period. The timeout period is adjusted in response to a change in one of the voltage and the motor speed. Additionally, a control system that implements the method, and a motor system that incorporates the control system. | ||
