Abstract
An apparatus that improves rotation of a shaft. The shaft has a cyclical cogging torque acting thereon in a first direction. A support member is adjacent the shaft. The shaft is operable to rotate relative to the support member. A first anti-cogging member is coupled to the support member. A second anti-cogging member is coupled to the shaft to rotate based on rotation of the shaft. A cam surface has a lobe that is included on one of the first and second anti-cogging members. An abutment member is coupled to the other of the first and second anti-cogging members. The abutment member is operable to abut against the cam surface to provide an anti-cogging torque to the shaft in a second direction that opposes the first direction to at least partially offset the cogging torque. The biasing member biases the abutment member toward the cam surface.
