Abstract
A driving device includes a motor and a control unit for controlling of the motor. The motor includes a motor body and an end cap assembly disposed at one end of the motor body. The motor body comprises a stator, a rotor rotatable relative to the stator, and a motor shaft fixed to and rotated with the rotor. The end cap assembly is provided with two brushes. The control unit includes two connectors for connecting with an external power source. The two brushes are respectively electrically connected to the connectors through the control unit. Lengths of connecting routes of the two brushes to the corresponding connectors are substantially equal to each other.
