摘要： A rotor 33, 133 for use in an electrical machine 100 having permanent magnets 34, 134 included therein, each permanent magnet 34, 134 between an adjacent pair of poles 32, 132, wherein each adjacent pole 32, 132 has an opposite polarity. Each permanent magnet 34, 134 has a magnetization polarity on its radially-outward surface 38, 138, and each adjacent permanent magnet 34, 134 has the opposite polarity on its radially-outward surface 38, 138. In addition, each pair of permanent magnets 34, 134 have the same magnetic polarity on their adjacently facing surfaces. This arrangement of permanent magnets 34, 134 may be used on electrical machines 100 having either a Lundell-type rotor 33 or salient pole rotor 133.

摘要： An electromechanically actuated valve (12) for use as an intake or exhaust valve in an internal combustion engine. The valve (12) is actuated by a electromechanical actuator assembly (18) which includes a first electromagnet (22), second electromagnet (30) and third electromagnet (32). A first disk (38) is slidably mounted to the valve (12) in a gap between the first and second electromagnets with first and second stop members (39, 41) limiting its travel along the valve stem (15). A third spring (52) biases the first disk (38) toward the first stop (39). The gap between the first and second stops (39, 41) is large enough to allow for manufacturing tolerances and temperature changes, with a third spring (52) acting to create soft landings. A second disk (44) is slidably mounted to the valve (12) above the third electromagnet (32) with a third stop member (40) limiting its travel toward the first disk (38). With the valve (12) being in a closed position, the gap between the first disk (38) and the first electromagnet (22) is greater than the gap between the second disk (44) and third electromagnet (32), allowing for multiple valve lifts. A first spring (48), mounted between the cylinder head (14) and first disk (38), and a second spring (50), mounted between the second disk (44) and an actuator housing (20), create an oscillatory system which drives the valve movement during engine operation, thus reducing power requirements to actuate the valves.

摘要： A method and system for maximizing the output of an alternator in an automotive vehicle. An alternator is provided having a first rectifier connectable to a first output of the alternator to form a first winding configuration and a second rectifier connectable to a second output of the alternator to form a second winding configuration. Based on the speed of the alternator, a controller operatively couples one of the first and second rectifiers to the first and second outputs, respectively, so as to maximize output current of the alternator. If the speed of the alternator is below a predetermined speed range, the controller couples the first output of the alternator to the first rectifier. Alternatively, if the speed of the alternator is above the predetermined speed range, the controller couples the second output of the alternator to the second rectifier.

摘要： A method and system for increasing the output of an alternator for an automotive vehicle has a first three-phase winding (18) and a second three-phase winding (20) that are coupled to a respective first rectifier circuit (26) and a second rectifier circuit (28). A switch circuit (30) is located between the first rectifier circuit (26) and the second rectifier circuit (28). A controller (32) that is coupled to a speed sensor (34) and provides a signal indicative of the speed of the alternator, controls the operation of the switch circuit (30). When the speed sensor (34) indicates that the speed of the alternator is below a predetermined threshold, the first rectifier circuit (26) and second rectifier circuit (28) are coupled together through switch circuit (30). When the speed sensor (34) indicates that the speed of the alternator is above a predetermined speed, the switch circuit (32) is controlled to an open state so that two parallel half-wave rectifier circuits are formed.

摘要： A fault isolation system for a three-phase induction motor drive system includes an inverter to convert direct-current power from a battery into alternating current for the three phases of the motor. The inverter contains six semiconductor switches, two for each phase of the motor, as is conventional in the art of induction motor control. Further, the inverter contains two additional semiconductor switches. These switches form an output connected, via a dummy load in parallel with a third additional semiconductor switch, to the neutral connection of the motor. In the event that any of the six conventional switches in the inverter become short-circuited, the four switches in the other two phases of the inverter as well as the two additional switches are actuated to generate current sufficient to blow a fuse connected in series with the output of the inverter coupled to the short-circuited switch. The motor is thus isolated from the short-circuited switch, preventing the short-circuited switch from totally disabling the motor. An alternative motor drive strategy, such as a two-phase drive strategy, can then be employed.
