Patent number: 6734589Abstract: The invention provides an electric motor in which a cost is reduced by reducing a number of the parts, and an electric motor in which a freedom of placement is increased. A motor assembly has a yoke and a front bracket closing an open end of the yoke. The front bracket is formed in a closed-end cylindrical shape by an aluminum die casting, and a brush holder for holding a brush is received in an inner portion. A motor controller for controlling the motor assembly is formed as an electronic circuit having a communication portion, a control portion and a driver portion, and this electronic circuit is mounted on an inner peripheral surface of the front bracket. Further, the electronic circuit constituting the motor controller may be mounted on the brush holder.Type: GrantFiled: May 7, 2002Date of Patent: May 11, 2004Assignee: Mitsuba CorporationInventors: Satoshi Kogure, Iwao Tsurubuchi, Wataru Mochizuki, Atsushi Maeda, Fumiaki Koshio, Tomohiro Usami, Yoshinari Tabuki
