摘要： A speed controller for utilization in a speed regulator system for a d.c. motor. An operational amplifier receives a voltage V1 through a first resistor R1, the voltage V1 being a function of the instantaneous speed of the d.c. motor. A second input to the operational amplifier is a speed reference signal. A feedback path connects the first input resistor R1 with an adjustable portion Alpha of the amplifier output Vo. The feedback path includes a second resistor R2 serially with capacitors C1 and C2; a third resistor R3 is connected between the union of capacitors C1 and C2 and ground. The speed controller is a proportional integrator squared (PI)2 having the Laplace transfer function:

摘要： A solid state switching circuit and power controller for permanent magnet and shunt field winding motors used in portable power tools and the like. The power controller employs a bidirectional thyristor triode and trigger diode for varying the current supplied to the motor armature, and a full-wave rectifier bridge to establish unidirectional current flow through the motor armature on opposite half cycles of the AC power supply. A resistor across the AC terminals of the rectifier bridge enhances control action under light loads.

摘要： A control circuit for clothes washing and spin-drying machines incorporating a pulse-producing circuit for generating a series of electric current pulses arranged to be applied to the gate of a thyristor for controlling the power supplied to the drive motor through the thyristor, and speed control means for regulating the pulsed output to give a relatively low-motor speed for washing and a relatively higher motor speed for spin drying, together with switch means operable to control the pulse-producing circuit directly to reduce the conduction angle of the thyristor and hence the power supplied to the motor, for example to zero, and so that the return of the switch means to initial condition causes the motor to be first energized in the low-speed condition, irrespective of the condition of the speedcontrol means, so that restarting the motor at full power is avoided.

摘要： A control circuit for a DC motor pulses the motor armature every half cycle, but maintains a discontinuous armature current as in a half wave motor control circuit. The assurance of discontinuity allows the motor e.m.f. to be used as a speed feedback voltage. The armature is placed across the output terminals of a full-wave rectifier comprising four controlled rectifiers. The input controlled rectifiers provide pulses of current to the armature. At the start of each half cycle the turn-on time of the output controlled rectifiers is delayed. With the latter controlled rectifiers turned off at the beginning of each half cycle, there is no current path which allows the armature current to decay slowly. The armature current is forced to go rapidly to zero and discontinuity of the armature current is assured.

摘要： A DC controlled-velocity drive. An SCR power bridge is energized by a three-phase AC power source for supplying DC voltage to the armature of a DC drive motor when the SCR''s are triggered, shifting of the phase of triggering causing variation of the DC voltage for varying the motor speed. Various regenerative and degenerative feedback circuits are employed, among them being a feedback circuit sensing this DC voltage and a feedback circuit sensing the motor armature current. These feedback circuits produce feedback signals which are compared with motor speed and armature current reference signals for the purpose of controlling the phase of triggering of the SCR''s in order to maintain the motor speed substantially equal to a preselected motor speed while preventing the motor armature current from exceeding a predetermined maximum.
