  • Patent number: 6734589
    Abstract: 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.

  • Patent number: 5786676
    Abstract: In a control circuit for a vehicle windshield wiper system, a relay energization retaining circuit forms a self-sustaining circuit jointly with a relay drive transistor for driving a wiper relay, and maintains supply of electric current to the wiper motor when the ON signal for the relay drive transistor is terminated as long as the auto stop switch is at the brake position until the auto stop switch subsequently moves on to the drive position.
