Abstract
A motor has a stator, a rotor, an end cover assembly installed on an axial end of the stator and the rotor. The rotor includes a shaft. The end cap assembly includes an end cap, a cover, and a circuit board arranged between the cover and the stator. At least one electronic element is mounted on the circuit board. The shaft passes through a hole in the cover. The cover and the shaft are made of a conductive material. With such structure damage to the circuit board and the electronic element due to high-voltage static electricity is avoided.
