The lengths of the zones of these first to third zones are 120 DEG in terms of electrical angle. One position detection device (10) fixed to a main body is so provided as to oppose the periphery of the rotary disc (15). When these zones pass by the device, three-phase position detection signals corresponding to these zones are generated.

摘要： A three-phase reluctance motor with a large output torque used to drive various pieces of industrial equipment, wherein two adjacent magnetic poles (16a and 16a') and two magnetic poles (16d and 16d') faced to the above magnetic poles in the direction of the motor diameter are provided for each of the first through third phases, the four magnetic poles are excited by four exciting coils (17a, 17a', 17d, and 17d'), and all exciting coils of each phase generate a large magnetomotive force. Thus, the limited magnetic coil arrangement space in the motor is effectively used, the magnetomotive force of the exciting coils is increased, and a large output torque is generated. Moreover, when the exciting coils (17a, 17a', 17d, and 17d') are not energized, the magnetic energy stored in the exciting coils comes into the exciting coils (17b, 17b', 17e, and 17e') of another phase and immediately decreases, and the exciting current in the exciting coils of another phase immediately rises to allow the motor to operate at a high speed.

摘要： A three-phase single wave power supply reactance type motor having a construction wherein at least two motors are juxtaposed inside a casing (42), so that the number of magnetic poles (16a, ...) and the number of salient poles can be made small and consequently a small-diameter long motor can be obtained. In the construction wherein n three-phase single wave motors are juxtaposed, the output torque is n times the torque of one motor. When a phase difference of 120°/n is provided for the output torque of each motor, torque ripple can be reduced and better start performance is obtained. Since magnetic energy stored in excitation coils (17a, ...) is fed back to a D.C. power source of a high impressed voltage, the extinction of magnetic energy is rapidly done to prevent the generation of counter-torque, and the storing of magnetic energy is also rapidly done by the impressed high voltage to prevent the generation of deceleration torque. Alternatively, the reflux of the stored magnetic energy of the excitation coils 917a, ...) to which the power supply is cut off, to the D.C. power source is prevented by diodes, and the great electromotive force at that time is used to accelerate the storage of magnetic energy of the excitation coils (17a, ...) to which the power is to be next supplied, so that the extinction and storing of magnetic energy are accelerated so as to prevent the generation of the deceleration torque and the counter-torque.

摘要： A reluctance motor comprising a fixed armature (1) and a rotor (5) of a magnetic substance disposed inside the armature (1) with a gap between them. Two salient poles (5a, 5b) having a width which is 2.5 times the angular pitch of slots (1a, 1b, ..., 1h) of the armature (1) are disposed round the outer peripheral portion of the rotor (5). A magnetic flux due to the excitation of armature coils (2h, 2d) of magnetic poles (4h, 4d) situated at positions at which no torque is generated is combined with the magnetic flux due to the excitation of armature coils (2a, 2e) of magnetic poles (4a, 4e) situated at positions in a direction of an arrow R at which a torque is generated. As a result, leakage fluxes Fa and Fb between the magnetic poles (4a, 4e) and the salient poles (5a, 5b) of the rotor (5) increase and the torque can be increased.

摘要： A power feed current is held at a set value by a chopper circuit, and part of the magnetic energy of cores of armature coils (32a, 32b, ...) is charged to small capacitors at a chopper frequency at the time of the stop of the power feed. In this way, energy loss resulting from iron loss and copper loss at the alteration of the power feed to the armature coils (32a, 32b, ...) is compensated for, and the rise of the power feed current can be sped up, and a high speed high torque reluctance type motor can be obtained. When the technology described above is applied to a three-phase D.C. motor having a magnet rotor (1) and to a stepping motor, the same action and effect can be obtained by the same construction.

摘要： A driving system for decreasing ripples in the output torque of a reluctance-type motor, wherein, during the operation of a motor (3), a data selecting-and-reading unit (51) decodes the output of an analog-to-digital converter (18a), selects a memory corresponding to the command exciting current outputted by a power control circuit among memories (51a through 51e), sequentially reads torque ripple data from the selected memory according to the address output of an address counter (57) which is updated every time an output pulse is sent out of a shaft encoder (6), and supplies the data to a power control circuit (61) through a digital-to-analog converter (59). The power control circuit corrects the command exciting current by using the torque ripple data and controls the motor with the corrected command exciting current to eliminate the ripples from the motor output torque.

摘要： A device for accurately controlling the current application to an inductance coil without any time lag. Connected to the terminal of an inductance coil (1) on the negative electrode side of a power supply is a semiconductor switching device such as a transistor (3), and thereby, a chopper circuit for supplying an exciting current proportional to a reference voltage is formed. By the magnetic energy when the current application to the inductance coil (1) is cut off, a capacitor (5) of a small capacitance is charged. Thereby the voltage is raised and the falling of the exciting current is made rapid. On starting the current application, the rise of the exciting current is made rapid by virtue of the high voltage of the capacitor (5). Therefore, the exciting current is precisely proportional to the reference voltage.

摘要： A motor of a high speed, high torque and high efficiency. In a motor of a reluctance type, etc., according to the present invention, when the current application to an armature coil (32a) is stopped via a switching device in connection with a negative voltage side, the magnetic energy stored in a magnetic core is prevented from flowing back to the power supply by a diode (21a) for blocking a reverse current, and flows into a capacitor of a small capacitance, charging the capacitor and holding the voltage at a high value. Therefore, the current in the armature coil decreases rapidly. After the lapse of a predetermined time, the next armature coil (32e) is energized. The high voltage of the capacitor is applied to the coil (32e) at this time. Therefore, the current of the coil (32e) increases rapidly. Since the rise and fall of the current applied to the armature coil are made sharp, the motor can rotate at several tens of thousands r.p.m. Another means is adopted. While the current is applied to the armature coil, an inductance coil is energized too. When the currents in both coils are stopped, the magnetic energy stored in both the coils is made to flow into the capacitor and charge it. By this stored energy, the next armature coil is energized. The means compensates the energy loss due to the copper and iron loss.

摘要： A reluctance-type electric motor capable of running at a high speed and producing a large output torque includes transistors (20a to 20f) connected to both ends of excitation coils (39a to 39c) of each of the phases, a current control circuit for energizing the excitation coils sequentially in response to a position detection signal that represents the rotor position detected by a position detection element, and diodes (21a to 21f) that connect the excitation coils to the capacitors (47a to 47c). When the flow of current to an excitation coil is discontinued, the associated capacitor is charged by the magnetic energy stored in the coil whereby the magnetic energy decreases rapidly, while the next coil is rapidly energized with the current from its associated capacitor that has been charged. The position detection element is secured to a predetermined position on an armature, and the current starts flowing into the excitation coil within a section of an electric angle of 30° from a point at which a salient pole begins to face the magnetic pole.
