Abstract

The utility model relates to a motor assembly (200) which comprises a commutator; an electromagnetic shielding cover (240, 240’) surrounding the commutator closely or semi-closely; and a bracket supporting the electromagnetic shielding cover (240, 240’), wherein the bracket comprises a bearing surface (236), and at least a portion of the electromagnetic shielding cover (240, 240’) is carried on the bearing surface (236) and is shaped to be conformed with the shape of the bearing surface (236). The utility model also relates to a wiper system comprising the above motor assembly. The electromagnetic shielding cover has a simple structure and a low cost, and it is easy to modify the electromagnetic shielding cover according to different types of motors.
