Abstract: A reliable and cost-efficient direct drive force feedback motor is suitable for joystick applications, allowing multiple degrees of output freedom, requiring no coil commutation, and permitting compact packaging. A multiple degree-of-freedom motor consistent with the invention comprises an output shaft, a stator, and a rotor. The stator comprises first and second lamination stacks, each lamination stack having an interior curved surface and a coil wound thereon, the lamination stacks being disposed adjacent the output shaft. The rotor is fixed to the output shaft and movably supported adjacent the stator with an air gap disposed between the rotor and the stator, the rotor including at least one magnet disposed thereon and being movable along the interior curved surface of the lamination stacks in directions defining at least first and second degrees of freedom. Energization of the coil of the first lamination stack establishes a first magnetic field to urge the output shaft to rotate in a first plane, and energization of the coil of the second lamination stack establishes a second magnetic field to urge the output shaft to rotate in a second plane substantially orthogonal to the first plane.

Abstract: An apparatus for converting between mechanical and electrical energy, particularly suited for use as a compact high power alternator for automotive use and “remove and replace” retrofitting of existing vehicles. The apparatus comprises a rotor with permanent magnets, a stator with a winding, and a cooling system. Mechanisms to prevent the rotor magnets from clashing with the stator by minimizing rotor displacement, and absorbing unacceptable rotor displacement are disclosed. The cooling system directs coolant flow into thermal contact with at least one of the winding and magnets, and includes at least one passageway through the stator core. Various open and closed cooling systems are described. Cooling is facilitated by, for example, loosely wrapping the winding end turns, use of an asynchronous airflow source, and/or directing coolant through conduits extending through the stator into thermal contact with the windings.

Abstract: An improved air gap baffle is disclosed for a dynamoelectric machine of the type having an air-tight casing filled with a cooling gas, a stator core, a rotor defining an air gap with the stator core, and a means for recirculating the cooling gas through the stator core and the rotor. The baffle is an annular member which is disposed in the air gap between the stator core and the rotor for defining air gap zones having different cooling gas pressures and/or gas flow in opposing directions. The baffle comprises a flexible abradable member having a serrated tip in sealing relationship with the rotor. The baffle improves sealing between adjacent air gap zones by minimizing running clearances and by providing a labyrinth seal. The flexible nature of the baffle reduces the possibility of damage to either the baffle or the rotor during assembly and thereby allows the dynamoelectric machine to be assembled with minimal running clearances between the baffle and the rotor. The baffle material is electrically nonconductive which serves to minimize eddy current losses in the dynamoelectric machine.
