Abstract
A wiper system for a motor vehicle window includes a wiper arm, a permanent magnet motor, a linkage connecting the motor with the wiper arm, and a switching mechanism. The wider arm is adapted to be rotatably mounted on a vehicle body for operable movement between first and second end wipe positions. The motor is of the three brush permanent magnet type, the brushes being a high speed brush, a low speed brush and a common brush. The switching mechanism is responsive to wider blade position and is closed, electrically connecting the high speed brush with the low speed brush, thereby achieving an intermediate speed, in at least one end wipe position.
