Disclosed herein is an alternate action solenoid drive circuit adapted for connection to a DC source having first and second power terminals and which can be incorporated in a DC motor control for a vehicle, also disclosed herein. The drive circuit comprises an actuator switch including go and ...
In the Ward-Leonard method of speed control of DC motors, regenerative braking is inherent, but thyristor drives have to be arranged to invert to regenerate. Induction motor driver can regenerate if the rotor shaft is driven faster than speed of the rotating field. The advent of low-cost ...
Providing the supply system has adequate capacity, the consequent rise in terminal voltage will be small during the short periods of regeneration. In the Ward-Leonard method of speed control of DC motors, regenerative braking is inherent, but thyristor drives have to be arranged to invert to ...
In general, the magnetic field of a dc motor can be produced by field windings or permanent magnets. Due to the popularity of PM dc motors in control system applications, we concentrate on this type of motor. PM dc motors can be classified according to commutation scheme and armature design....

DC MOTOR CONTROL USING CHOPPER This paper deals with DC motor control in a high performance manner. The DC motor control system is designed and performed using a chopper circuit. The four different parts of control of DC motors will be considered here. Using chopper a... N Afrasiabi,M. Yaz...
This work describes the study of modeling and controller on wheeled mobile robots designed the motors which is driving the wheels. According to the structure and design of wheeled mobile robot, DC motors are the best suited for the motion control. The kinematical model is required for the design...
In armature-controlled DC motors, the applied voltage Va controls the angular velocity w of the shaft. This example shows two DC motor control techniques for reducing the sensitivity of w to load variations (changes in the torque opposed by the motor load). A simplified model of the DC motor...
