Drive device for motor car, has control unit that is provided for confinement of gradient of current flowing through direct current (DC) motor by controlling voltage resting against DC motor in dependence of measured current gradient

摘要

The drive device comprises a direct current (DC) motor (1) with three coils, and a control unit (14). A measuring unit (11) is configured for measuring a gradient of the current flowing through the DC motor. The control unit is provided for confinement of the current gradient by controlling the voltage resting against the DC motor in dependence of the measured current gradient.
