摘要： 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.

摘要： Apparatus controlling switching of a polyphase switched reluctance motor (M). There is a set (10-16) of windings for each motor phase, each set of windings including at least two separate windings (10A, 10B-16A, 16B). One winding (10B) from one set (10) of windings is connected together with one (12A) winding from another set (12) of windings to form a combined set (10C) of windings. Each winding from the one set of windings is connected only to the one winding from the other sets of windings thereby to produce a number of combined sets of windings corresponding to the number of motor phases. A motor controller (18) selectively energizes and de-energizes the combined sets of windings in a predetermined sequence through an inverter (20). One switch (22a) operated by the inverter is interposed between the controller and one side of each of the combined sets of windings; and, a second switch (22b) is interposed between the inverter and the other side of each of the combined sets of windings. Closing the switches causes energization of windings in two of the motor phase so at least two motor phases are simultaneously energized at any time during motor operation.

摘要： A polyphase dynamoelectric machine (10) such as a switched reluctance motor has a stator assembly (12) and a rotor assembly (14). The rotor assembly is movable with respect to the stator assembly. The stator assembly includes a stator (16) having a plurality of stator poles (18). The rotor assembly includes a rotor (20) having a plurality of rotor poles (22). The stator assembly further includes a plurality of separately energizable stator windings (24) associated with the respective machine phases. These stator windings are energized and de-energized in a predetermined sequential manner to sequentially activate and deactivate the machine phases. Energization and de-energization of the respective stator windings is at least partially determined as a function of the machine's instantaneous rotor position. The machine includes a processor (26) for determining the rotor position. The processor monitors the waveform of a circulating current coupled from an energized stator winding for an active machine phase into a de-energized stator winding for an inactive machine phase. Respective energized and de-energized stator windings are interconnected to form a closed circuit path by which the current in the energized stator winding is coupled into the de-energized stator winding. Monitoring the resultant current waveform provides an indication of rotor position, and the processor uses this information to energize and de-energize the stator windings.

摘要： Apparatus (10) for controlling the current profile (P2) in a single or polyphase SRM (M) during the active portion of a phase. Switches (S1, S2) are closed during an active portion of a phase to direct current flow into a winding (W). A Hall effect sensor (14) and other sensors are used to sense various operating parameters of the SRM. A PWM signal generator (16), or microprocessor (20) is responsive to the sensor inputs to provide PWM operating signals (G2) to at least one of the switches to control current flow to the winding. The operating signals modulate the switch(es) for switch operation to be controlled as a function of the signal characteristics of the operating signals. This allows the current supply to the winding to be in accordance with the current profile. According to the profile, current flow is initially rapidly increased from zero to a peak value (I.sub.p ') when the phase becomes active. The current is then allowed to decrease from this peak to a second and lesser value (I.sub.p) by the time the phase becomes inactive. Current decays from this second value to zero when the phase becomes inactive. The transition in the current profile which occurs when the phase switches from active to inactive is no longer an abrupt transition, but is rather a more moderate one. This smoother transition reduces the amount of ringing in the motor, which normally occurs when current flow into the winding ceases, thereby to reduce motor noise.

摘要： 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.
