This paper presents a DC motor speed controlling technique under varying load condition. The linear system model of separately excited DC motor with Torque-variation is designed using PID controller.

Speed Control of Motors Speed, torque, and horsepower are three inter-related parameters in motor control. The speed of a motor, measured in revolutions per minute (rpm), defines a motor's ability to ...

It’s an excellent way to learn about both PWM motor control and the use of 555 timers, all with a very low parts cost and readily available components. We’ve seen such setups before, used as ...

Speed control Torque control Motor protection Implementation of these control functions requires monitoring of one or more motor parameters and then taking corresponding action to achieve the required ...

This can, however, be addressed using Field-Oriented Control (FOC) sinusoidal BLDC motor control. In the next part of this article, we will address controlling the speed, position, and torque of BLDC ...

For motors controlled by a variable frequency drive (VFD), the control method used in large part determines a motor’s efficiency and performance in an application.

Rotational Speed When you write software to control a stepper motor, you must first know how many pulses the motor needs to turn a full rotation.

Power density in a dc motor is the quantity of power that a motor is able to have per unit volume—essentially a power-to-mass ratio.
