Abstract
A method and device for determining the motor moment constant kof an electric motor by measuring motor parameters on the running motor. For reduction of the previously considerable measuring effort it is proposed that firstly the generator voltage Uproduced by the motor is measured, and in that the motor moment constant kis calculated by division of the generator voltage Uand the speed of rotation fof the motor, taking into consideration at least one further constant. The method and the device are suitable for DC motors and for 3-phase synchronous motors.
