A windshield wiper assembly including at least one motor having an output shaft and a windshield wiper operatively connected to the output shaft. The motor includes a stator adapted to provide an electromagnetic flux and a rotor assembly supported for rotation about the stator. The rotor assembly includes a back iron that defines an inner circumference and a plurality of magnets disposed in spaced parallel relationship relative to one another about the inner circumference of the back iron and in radially spaced relationship about the stator. The rotor assembly is operatively connected to the output shaft and responsive to electromagnetic flux generated by the stator so as to provide a rotational force to the output shaft to drive the windshield wiper in repeated wiping motion across the windshield.

Direct drive windshield wiper assembly

A tandem windshield wiper system including a first windshield wiper assembly having a first lever arm that is adapted to operatively move in a repeated wiping motion across the surface of a windshield. A second windshield wiper assembly having a second lever arm is spaced apart from the first windshield wiper assembly and is rotatable about a second wiper longitudinal axis and adapted to operative move in a repeated wiping motion across the surface of the windshield. A brushless DC motor that includes a planetary gear set having an output shaft is disposed between the first and the second wiper assemblies. The gear set is operable to reduce the speed of the rotational output of the motor through the output shaft of said gear set. A bellcrank having a central attachment point and a first and a second end is also included. The central attachment point is fixedly mounted to the output shaft of the motor. A first connecting arm is operatively disposed between the first lever arm and the first end of the bellcrank and is adapted to translate the drive torque from the motor to the first windshield wiper assembly. A second connecting arm is operatively disposed between the second lever arm and the second end of the bellcrank and is adapted to translate the drive torque from the motor to the second windshield wiper assembly.

Tandem windshield wiper system with bellcrank linkage

A tandem windshield wiper system that includes at least one brushless DC motor to provide drive torque through an output that is rotatable about the longitudinal axis of the motor. A first windshield wiper assembly having a first lever arm is driven by the motor about the longitudinal axis in a repeated wiping motion across the surface of a windshield. A second windshield wiper assembly spaced apart from the first windshield wiper assembly has a second lever arm and is rotatable about a second longitudinal axis to operative move in a repeated wiping motion across the surface of the windshield. A connecting arm is also included that is operatively disposed between the first and the second lever arms that is adapted to translate the drive torque provided to the first windshield wiper assembly to the second windshield wiper assembly. The motor includes a planetary gear set having an output shaft. The gear set being coaxially disposed relative to the rotational output and the longitudinal axis of the motor and operatively interconnecting the drive torque to the first and the second windshield wiper assemblies.

Tandem windshield wiper system with direct drive motor

A windshield wiper assembly including at least one motor having an output shaft and a windshield wiper operatively connected to the output shaft. The motor includes a stator adapted to provide an electromagnetic flux and a rotor assembly supported for rotation about the stator. The rotor assembly includes a back iron and an annular magnet mounted to the back iron so as to be disposed in radially spaced relationship about the stator. The rotor assembly is operatively connected to the output shaft and responsive to electromagnetic flux generated by the stator so as to provide a rotational force to the output shaft to drive the windshield wiper in repeated wiping motion across the windshield.
