20130205807 | MOTOR AND SYSTEM CONTROLLER - A beverage cooler has a low voltage DC supply ( | 08-15-2013 |
20120313463 | ROTOR OR STATOR EMBEDMENT - A rotor for a motor or generator is produced by placing separated magnets around the diameter of the potential rotor, placing separated segments of magnetic backing material behind the magnets, and embedding the whole in molding material in a mold in such a way that the segments thrust outwards against the magnets and the magnets thrust outwards against the mold during placement of the molding material. | 12-13-2012 |
20110050020 | ELECTRONIC MACHINES WITH COMPOSITE POLES - An electric motor or generator consists of a stator carrying pole pieces and their coacting coils, the stator being surrounded on one side by the field creating permanent magnets adjacent one face of the poles and on the other by a flux return path element positioned adjacent the other face of the poles. The stator coils are preferably bobbin mounted. | 03-03-2011 |
20100207557 | CONTROL OF SYNCHRONOUS ELECTRICAL MACHINES - A synchronous motor having phase windings which are split or tapped and in which the conduction angle of the applied alternating current is varied at one or more taps to allow the motor to start in a controlled direction and be torque controlled to synchronous speed. | 08-19-2010 |
