Abstract:
A PMDC motor, particularly for driving an automobile liftgate, comprises a stator and a rotor rotatably mounted to the stator. The stator comprises a housing and an end cap mounted to one end of the housing. The end cap comprises: a first brush, a second brush, a first terminal, a second terminal, a first choke connected in series with the first brush and the first terminal, a second choke connected in series with the second brush and the second terminal, an overcurrent protection component connected in series with the second brush, and a set of capacitors. Each of the chokes comprises an inductor core extending axially and a winding wound about the inductor core.
