Abstract: Permanent magnet machines including doubly salient machines having one or more permanent magnets located at least partly and preferably entirely within the stator teeth, thereby avoiding weakening of the stator structure while reducing acoustic noise. The magnets may be located in only a subset of the stator teeth, thereby lowering magnet material and manufacturing costs, and all such magnets may have north poles directed toward an interior of the machine, resulting in reduced cogging and negative torques with improved torque densities. The permanent magnets may also extend within the stator teeth on an angle or diagonal, thereby allowing use of magnets which are wider than the teeth themselves to produce greater flux. Further, a magnetizing device having a single coil may be used to simultaneously magnetize all the stator magnets with a common polarity.

Abstract: A control circuit (10) for controlling the residual or tail current decay in a single phase or polyphase SRM winding when a phase is switched from active to inactive. A Hall-effect type sensor (30) senses rotor position of the SRM. Current flows through a winding (W) of the motor when the motor phase winding is active; and, current flow into the winding decays to zero when the phase becomes inactive. Semiconductor switches (22) direct current flow into the winding when the phase is active and then redirect residual energy in the winding between an energy recovery circuit and an energy dissipation circuit when the phase becomes inactive. A PWM signal generator (44) provides PWM operating signals to the switches to control current flow first into the winding and then between the recovery and dissipation circuits. A control module (42), or microprocessor (52) with a PWM output, is responsive to rotor position information for controlling operation of the PWM signal generator. The signal generator provides PWM signals having one set of signal characteristics when there is current flow to the winding and a different set of characteristics when there is not. This produces alternate intervals of zero voltage and forced commutation residual current decay while the phase is inactive. During the decay interval, both the PWM frequency and pulse duty cycle are variable to produce a current decay scheme which eliminates ringing and motor noise.

Abstract: Sensing apparatus for use on a polyphase switched reluctance motor (M, M'). The motor has a stator assembly (SA) and a rotor assembly (RA) including a rotor shaft (S) on which the rotor assembly is mounted for rotation with respect to the stator. Each respective motor phase is switched between active and inactive states by a commutator controller (C) responsive to sensed motor operating conditions. Switching a phase to its active state includes supplying current to the respective rotor phase windings, and switching the phase to its inactive state includes cessation of the current supply. Accordingly, there is a turn-on, running, and turn-off portion of each cycle of current supply with the turn-on portion of the cycle lasting approximately 30%-45% as long as the turn-off cycle. The apparatus includes a magnetic ring (10, 10') installed on the rotor shaft and rotatable therewith. It also includes a sensor (12, 14) for sensing changes in a magnetic field produced by the ring as it rotates with the shaft. The magnetic ring has a set of magnetic poles for each motor phase. The portion of the circumference of the ring subtended by one of the poles of each set is greater than that subtended by the other pole of the set. Respective portions of the circumference subtended by the poles in each set is proportional to the turn-off time to the turn-on time.

Abstract: A brushless, permanent magnet dynamo-electric machine (50) has a stator assembly (52) and a rotor assembly (RA). The rotor assembly includes a rotor (R) mounted on a rotor shaft (RS). The stator assembly has a plurality of inwardly salient poles (54) and the rotor has a plurality of outwardly salient poles (RP). The rotor is comprised of a plurality of stacked rotor laminations (L) defining the rotor poles, and there is an air gap (G1) between the rotor and stator poles. An improvement (56) of the present invention controls the available flux coupled between the rotor and stator assemblies. A coil (70) is supported on a magnetic mounting structure (66) which is connected to an endwall (W) of the motor housing and fits the coil over the rotor shaft. D.C. current is supplied to the coil. A plurality of magnets (82a, 82b) extend the length of the lamination stack and the magnets are positioned adjacent an outer face of one pole for each set of rotor poles. The magnets are mounted on support structure (72) that extends about the coil. The magnets magnetically attach to the outer surface of the rotor poles to suspend the structure about the shaft. An air gap (G2) extends between the coil and shaft. The magnets rotate in synchronism with the rotor. The current supplied to the coil controls the flux coupled to the rotor, and the mounting structures for the coil and magnets partially define a diversion flux path for the resultant flux.
