    摘要： A brushless D.C. motor has a rotor with a plurality of magnets secured to a mounting surface. Each magnet has an RF transmitter secured to a magnet surface, with each RF transmitter having stored therein a unique identification character serving to identify the magnet. A transmitter power generator having several coils mounted on the rotor and a power conditioning unit supplies power to the transmitters, which continuously broadcast their identification character. A stator has a plurality of pole teeth separated by slots, each pole tooth having a power coil wound thereabout. A plurality of RF receiver antennae are mounted adjacent the pole teeth each coupled to a different RF receiver. The position and magnet identification information received by the RF receiver is processed and coupled to a microprocessor, which extracts the information and sends it to a motor controller and driver unit, which supplies operating power to the individual power coils.

    摘要： The present disclosure is directed to a method for generating power for a machine. The method may include inverting a common power at a first location and outputting a first inverted power. The method may further include inverting the common power at a second location, outputting a second inverted power, and shifting an operational phase of the second inverted power so that the first inverted power and the second inverted power are in phase. The method may further include passing the first inverted power to a transformer, passing the second inverted power to the transformer, and transforming the first inverted power and the second inverted power to a transformed power.

    摘要： A commutator has a conductive layer, a segment layer and an insulatim layer separating the conductive layer and the segment layer. The segment layer includes multiple commutator segments. A mounting hole is defined along an axis of the commutator passing through the conductive layer. The three-layer structure of the commutator forms a capacitor having an increased confronting area and reduced inter-plate distance. The capacitor thus has a greater capacitance and hence greater EMI absorbing capability, making it possible to reduce EMI emissions without additional EMI reduction components outside the commutator. A rotor and a motor employing the commutator are also disclosed.

    摘要： An electric direct current motor is disclosed which includes a shaft, a winding support, a collector having several collector wires, and an air-cored outer rotor winding with several winding terminations. The outer rotor winding is at one end connected to the shaft via the winding support in a torque-proof manner, and is electrically connected with the collector. The winding support can be replaced by a printed circuit board as a bearing component of glass-fiber reinforced thermosetting plastics, wherein the printed circuit board includes at least one layer and is connected to the shaft via a metal hub.

    摘要： A motor includes a rotor, a commutator, a brush, and a bias member. The commutator has a rectifying surface. The commutator rectifies an electric current supplied to the rotor through the rectifying surface. The rotor is rotated by being supplied with the electric current. The brush makes contact with the commutator via the rectifying surface. The rotor is supplied with the electric current through the brush. The brush starts making contact with the commutator on an entry side of the brush as the rotor and the commutator rotate with respect to the brush along a rotative direction and the commutator intermittently makes contact with the brush. The bias member biases the brush toward the entry side.

    摘要： A commutator has a base, a plurality of commutator segments mounted on the base and a noise suppression element. The noise suppression element is electrically connected to the segments by a connecting element, in the form of an elastomeric ring having conductive portions, which is compressed between the noise suppression element and the commutator segments, or terminals associated with the commutator segments, to avoid the need to solder the noise suppression element to the segments.
