摘要： A speed detecting apparatus having a detector (101) for generating two sine-wave signals (PA, PB) which are .pi./2 out of phase with each other and have a frequency proportional to the speed of rotation of a motor so that actual-speed voltages (V.sub.L, V.sub.H) can be produced which are proportional to the speed of rotation of the motor. The speed detecting apparatus includes a quadrupling circuit and a frequency-to-voltage converter 107. Also included is a first speed generator for generating the actual-speed voltage (V.sub.H) in a high-speed range and a second speed generator which includes a four-phase rectangular signal generating circuit (106), a differentiating circuit (109), and a synchronous rectifier circuit (110) for producing the actual-speed voltage (V.sub.L) in a low-speed range. The voltages generated by the first and second speed generators are selectively issued as an output depending on whether the motor rotates at a high speed or a low speed.

摘要： A speed detector including a circular rotational member having a plurality of equally spaced-apart teeth on the outer circumference thereof, and first and second magnetic sensors. The first and second magnetic sensors each comprise a permanent magnet, a magnetic pole which permits the passage therethrough of a magnetic flux generated by the permanent magnet, and a detection coil wound on a portion of the magnetic pole. The magnetic poles of the first and second magnetic sensors are disposed in close proximity to, and arranged to face, the teeth on the rotational member, whereby each magnetic sensor produces an alternating output signal as the rotational member rotates, the frequency of each output signal being proportional to the speed of the rotational member. The direction in which the rotational member rotates can be detected by disposing the magnetic poles of the first and second magnetic detectors such that one of them is displaced circumferentially with respect to the other by an angular distance which is equivalent to 1/4 of the pitch of the teeth arrayed on the rotational member.

摘要： An induction motor drive apparatus brings the actual speed of an induction motor into coincidence with a command speed by varying the frequency and effective value of a three-phase AC voltage applied to the induction motor and limits the torque of the induction motor in the low speed region by controlling an amplitude of a speed deviation signal below a prescribed value. The apparatus includes an inverter for generating three-phase AC voltage, a speed deviation signal generator, a torque limit signal generator, an amplitude controller for controlling the amplitude of the speed deviation signal based on the presence of the torque limit signal, a slip signal generator which generates a slip signal having a positive or negative constant voltage conforming to the rotational direction of the induction motor, an adder for adding together a voltage signal which conforms to the actual speed and the slip signal, a rectangular waveform signal generator, a multiplier for multiplying an output of the amplitude controller by an output of the adder and a pulse width modulator. The rectangular waveform signal generator is adapted to produce a three-phase rectangular signal whose frequency is proportional to the output voltage value of the adder. The rectangular signal of each phase is modulated in pulse width on the basis of the speed deviation, the inverter being controlled by each resulting pulse-width modulated rectangular signal to thereby vary the effective value of the three-phase AC voltage and to make the speed of the induction motor constant.
