    摘要： Apparatus and method for detecting rotor (12) position in a switched reluctance motor (18) having multiple stator phases (A-A', B-B', and C-C'). A multiplexer (48) intermittently connects a known resistor (54) to a non-conducting stator phase. Circuitry (62 and 68) detects the amplitude of the current passing through the resistor (54) and the phase difference between the varying voltage and the current passing through resistor (54). The resulting signal is proportional to the position of rotor (12).

    摘要： A driving system capable of producing large driving force to drive a load and positioning it rapidly with high accuracy by use of a controller capable of driving a motor at a high speed with high torque and high efficiency. When target position data from a computer (35) is stored in a counting circuit (30) of an operation mode switching circuit (330), a load member is driven at a high speed by a large driving force through a ball screw-nut mechanism by a motor operating as a two-phase reluctance motor at a high speed with high torque and high efficiency. When the count value of the counting circuit which is decremented with the movement of the load member reaches a first set value, the sequence of application of the position detection signals indicating the motor rotating position to a power control circuit is changed by the signal switching circuit (320), and the motor is thus decelerated until the motor speed reaches a predetermined speed. The motor is then operated at a constant speed. When the count value drops to a second set value, the motor is driven as a stepping motor in accordance with a signal from a stepping signal generation circuit (27, 28a-28c). When the count value becomes zero, the motor stops and positions accurately the load member to a target position.

    摘要： A control system (10) for a polyphase variable-reluctance motor synthesizes direct- and quadrature-axis currents (id, iq). The magnitude of the direct-axis current (id) is a function of the terminal voltage (Vt) and rotor speed. The magnitude of the quadrature-axis current (iq) is a function of rotor speed. Waveforms, the amplitudes of which reflect the magnitudes of id and iq, are first summed, and are then supplied to an inverter (20) which supplies appropriate currents (ia, ib, ic) to the motor windings (21A, 21B, 21C). In use, the improved control system performs a unique method of controlling the operation of such a motor by selectively controlling id and iq.
