摘要:
A method for determining the temperature of a brushless d-c motor with a permanent-magnet rotor and an at least three-phase winding with electronic commutation including determining the curve of an EMF induced in a winding during one phase wherein the winding is in currentless condition, and evaluating the temperature therefrom.
