が米国特許第４．６８４．８６７号に示されている。That is, both the stator and rotor have a large number of magnetic poles. Additionally, the stator has coil windings, but the rotor has no windings or magnets. In an SRM, each phase of the motor has at least one pair of diametrically opposed stator poles, and each stator pole is wound with a coil winding. The stator pole coil windings that make up each phase winding of a motor are connected in series or parallel, so that when one phase winding is excited, the stator poles of the corresponding pair(s) The generated magnetic fluxes combine additively. When a phase of a motor is excited by supplying current to the corresponding stator pole coil winding, a voltage between the excited stator pole pair(s) and the nearest rotor pole Magnetic attraction acts, thus causing the rotor to rotate. The current in each excited phase winding of the motor is switched off before the rotor poles rotate past the alignment position. Otherwise, negative or braking torque will be generated due to magnetic attraction. Continuous rotation of the rotor is achieved by sequentially switching each adjacent phase of the motor on and off. To excite each phase of the motor, non-directional current pulses synchronized with rotor motion are supplied by the converter to each phase winding of the motor. An example of a converter for SRM is shown in US Pat. No. 4,684,867.

ク及び電圧が制限される。Generally, when manufacturing a switching motor, the coil windings are wound as a subassembly and then applied to the stator poles. This conventional stator assembly process has the disadvantage that it necessarily leaves unused space in each interpole region. That is, the width of a coil is limited in order to assemble it to a stator pole so that it can avoid touching adjacent windings that have already been assembled. As a result, the maximum flux, and therefore output torque and voltage, that can be achieved is limited for a particular SRM.

Applies to. The number and type of conductor turns used to create a particular sRM coil winding is related to its intended use. For windings constructed with a relatively small number of turns of heavy gauge conductor, each winding is formed into a predetermined coil shape corresponding to the dimensions of the respective stator pole. The stiffness of the thicker gauge conductor allows the coil to maintain its shape after being wound with a former. The conductors that make up the coil wound with the former are tightly packed. Alternatively, depending on the SRM and its intended use, the former-wound coil may be formed from multiple turns of thin-gauge conductor; , each turn is wound on a non-metallic bobbin.

れる。In order to maximize the utilization of each interpolar space 36, both the inner and outer windings are preferably of generally rectangular cross-section as shown. Furthermore, for SRMs of comparable dimensions, the width W1 of the inner coil winding of the present invention is preferably the same as the width of the conventional coil winding shown in FIG. Additionally, as with conventional coil windings, the inner coils are sized to fit directly or snugly into the corresponding stator poles. Choosing the dimensions of the inner coil winding as just described requires that the height H2 of the outer coil winding be less than the height H1 of the inner coil winding, as shown in FIG. The outer coil windings are sized to fit directly around the corresponding inner coil windings. The width W2 of the outer coil winding is limited by the clearance required for assembly, as will be explained in detail below.

Insert them into each. Each outer coil winding is then connected in series with its respective inner coil winding so that the overall winding direction is the same. Finally, connect the diametrically opposed stator pole coil windings in series or parallel as desired.
As a result, the magnetic flux pattern 111 is set to hl, which is similar to that of the conventional SRM shown in FIG.
