摘要:
A control device for electric motors and a method for monitoring the serviceability of a transmission part arranged for transmission of torque between an electric motor and a load during operation. The method comprises the steps of initiating at least one test sequence, and sending a signal indicating an error if said at least one test sequence indicates that the serviceability of the transmission part is not acceptable and if no further test sequences are to be performed. Additionally, said at least one test sequence includes the steps of setting a rotation speed of the electric motor at a test rotation speed, which differs from the rotation speed of the electric motor immediately prior to said setting, and measuring at the electric motor, within a period starting from the setting of the rotation speed of the motor and ending when the rotation speed of the electric motor has reached the test rotation speed.
