Control of a brushless motor |
摘要 |
A method of controlling a brushless motor that includes sensing a temperature and using the sensed temperature to define a current limit. A lower current limit is then defined for a lower sensed temperature. A winding of the motor is sequentially energised and de-energised, with the winding being de-energised when current in the winding exceeds the defined current limit. |
