Abstract: An anti-cogging apparatus includes a first support member, a second support member, a first set of magnets, and a second set of magnets. The first support member is configured to be connected to and rotate with a rotatable shaft. The second support member does not rotate and is configured not to move with the first support member. The first set of magnets is mounted on the first support member in an alternating polarity or a non-alternating polarity configuration. The second set of magnets is mounted on the second support member in an alternating polarity configuration or a non-alternating polarity configuration. The first set of magnets magnetically interacts with the second set of magnets to provide an anti-cogging torque on the rotatable shaft.

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

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.

Abstract: An anti-cogging apparatus improves rotation of a rotatable shaft about an axis. The shaft has a cyclical cogging torque acting thereon in a first direction. The anti-cogging apparatus includes a first anti-cogging member and a second anti-cogging member that rotate relative to each other in concert with rotation of the shaft, and the anti-cogging members interact to provide an anti-cogging torque to the shaft in a second direction to at least partially offset the cogging torque.

Abstract: A two-piece cable mounting arrangement is provided for a vehicle gearshift mechanism support base comprising an upper-half section and a bottom-half section of molded synthetic plastic material adapted to receive a pair of tubular cable guides end fittings therebetween. An upstanding bolt is fixed to the support base and extends through a central boss integral with the bottom-half section. The bottom-half section includes a pair of support blocks having concave troughs cradling an associated end fitting on either side of the boss. The upper-half section has a central wall portion receiving the bolt therethrough whereby the wall portion rests on the boss. The wall portion is formed with a pair of downwardly facing concave half-circle sectioned shell portions matching the pair of concave troughs such that each end fitting is captured between its associated lower trough and upper shell portions. The wall portion has an undercut locating notch interlocking with an upstanding tongue portion of the base.

Abstract: A ventilation system is provided for dynamoelectric machines such as hydro generators having salient pole rotors and in which the rotor and stator have separate ventilation systems sealed from the air gap. The stator ventilation system includes radial vent ducts in the stator core with longitudinal ducts extending between adjacent radial vent ducts in the tops of the winding slots. The longitudinal ducts are formed by two radially spaced wedges in each slot defining an axial passage between them, and the ducts are sealed from the air gap by the wedges and by sealing members at the inner ends of the radial ducts. Ventilating air flows radially inward through the vent ducts, longitudinally through the longitudinal ducts from one vent duct to the next, and radially outward to the external circuit where it is circulated through coolers by means of a blower or otherwise.
