ABSTRACT:
A device and method for detecting the coil temperature of a direct-current motor by determining the resistance of at least one coil of the motor. The method includes measuring a parameter of the at least one coil while the motor is running. The measurement is made at a time interval in which the coil is without current. The measuring device includes a commutation circuit of the motor which generates a time interval used for measuring the current.
