METHOD AND ARRANGEMENT FOR DETERMINING THE POSITION OF A ROTOR IN A BRUSHLESS MOTOR OR IN STEPPER MOTOR |
摘要 |
Method for determining the position of a rotor in a brushless motor or in a stepper motor, said method including the following steps: applying a voltage in at least one powered phase of the motor; measuring, in an unpowered phase of the motor, the voltage induced by mutual inductance between phases; and determining said position and/or the speed of the rotor from said induced voltage. |
