Abstract
In a method for monitoring the operation of an electric motor and a lifting mechanism, the motor current is acquired, and the electric motor has, for example, an electromagnetically actuable brake, e.g., a holding brake. In the method, a pre-magnetization is performed when the electric motor is switched on, the characteristic of the acquired values of the motor current is monitored for an exceeding of a permissible measure of deviation from a setpoint characteristic, and a brake of the electric motor is activated, e.g., remains applied.
