Control of dc motor

DC motor speed control can be achieved by varying flux, armature voltage. An also find about PWM based speed control system using microcontroller. To control the direction, the polarity of the motor is reversed.

Speed control is either done manually by the operator or by means of some automatic control device. One of the important features of DC motor is that its speed can be controlled with relative .

A common actuator in control systems is the DC motor.

It directly provides rotary motion an coupled with wheels or drums and cables, can provide translational motion.

The electric circuit of the armature and the free-body diagram of the rotor are shown in the following figure: For this example, we will . The electric equivalent circuit of the armature and the free-body diagram of the rotor are shown in the following figure. We will design the controller to achieve a . In this Arduino Tutorial we will learn how to control DC motors using Arduino. KB offers models of Variable Speed DC Drives that cover the most popular voltages and horsepower ranges for DC Motor Speed Control , DC Drive Acccessories, and DC Motor Controllers.

For the speed control of DC Motor the variation in voltage, armature resistance and field flux is taken into consideration.

A motor is an actuator, converting electrical energy in to rotational mechanical energy. Motor requiring DC supply for operation is termed as DC motor. DC motors are widely used in control applications like robotics, tape drives, machines and many more.

Separately excited DC motors are suitable for control applications . This example shows the comparison of three DC motor control techniques for tracking setpoint commands and reducing sensitivity to load disturbances: feedforward command.

Lecture Series on Control Engineering by Prof.

Agashe, Department of Electrical Engineering,IIT Bombay. A direct current, or DC , motor is the most common type of motor. DC motors normally have just two leads, one positive and one negative.

If you switch the leads, the motor will rotate in the opposite direction. The considered control system consists of two feedback loops.
