Abstract
An electric motor for operating a device for wiping a window of a motor vehicle has an electric motor part, and a control device for controlling/regulating a power of the electric motor part, the control device being formed so that it is programmable with a parameter a power limiting by limiting a torque to a nominal torque.
Claims10
An electric wiper motor for operating a device for wiping a window of a motor vehicle, comprising an electric motor part;
- and a control device for controlling/regulating a power of said electric motor part, said control device being programmable with a parameter for a power limiting by limiting a torque to a nominal torque of said electric motor part so that the electric wiper motor is a torque-limited motor.
A series of electric wiper motors each having an electric motor part, and a control device for controlling/regulating a power of said electric wiper motors, said control device being programmed with parameter P for power limiting by a limiting torque to a nominal torque, so that a power of each of the electric wiper motors of the series is limited to an identical maximum nominal torque so that the electric wiper motors are torque limited electric wiper motors.
A method of producing an electric wiper motor for wiping devices of motor vehicles including en electric motor part and a control device programmable with a parameter P for a power limiting by limiting a torque to a nominal torque, the method comprising the steps of mounting individual components of the electric wiper motor;
- determining a power variable;
- determining a parameter P for power limiting;
- and inputting the parameter P into a control device so as to form the electric wiper motor as a torque-limited electric wiper motor.
