Motor controller for controlling an electric motor |
摘要 |
A motor controller for controlling at least one electric motor has an operating signal generator for generating an operating control signal for the at least one electric motor and also a sound signal generator for generating a sound control signal. A mixer superimposes the sound control signal on the operating control signal in order to obtain a control signal for the at least one electric motor. It is then possible to dispense with loudspeakers and the like in the appliance which contains an electric motor with such a motor controller in order to output, for example, signal tones which indicate an operating state of the appliance to the user. |
