ELECTRONICALLY SWITCHABLE MOTOR WITH OVERLOAD PROTECTION

摘要

The invention relates to a motor which can be electronically switched, whereby the output stage can be controlled via an electronic control unit by means of PWM control signals and fed by power supply voltage. According to the invention, a limit for a maximum load with overload protection is achieved in that the pulse width of the PWM control signals for the output stages can be reduced to widths which prevent an overload of the motor and the electronic components by limiting motor power depending on the value of power supply and the predetermined desired value of the PWM control signals, at least, once the nominal voltage of the motor is exceeded.
