Circuit Diagram for DC Motor Control by A. Collins

A DC motor is an electric motor that runs on direct current (DC) electricity. Every DC motor has six basic parts — axle, rotor (a.k.a., armature), stator, commutator, field magnet(s), and brushes. The geometry of the brushes, commutator contacts, and rotor windings are such that when power is applied, the polarities of the energized winding […]

Circuit Diagram for Motor Control Sensor by Jim Lepkowski

This Motor Control Sensor Feedback Circuit Diagram article is written by Jim Lepkowski from Microchip Technology Inc. Sensors in motor control are used to sense the current, position, speed and direction of the rotating motor. In most motor control systems, several sensors are used to provide feedback information on the motor. These sensors are used […]

Motor Speed Control Using PWM

Pulse width modulation or familiarly known as PWM is used to control the delivered power to load without loosing the efficiency. The speed of an electric motor is controlled by controlling the power source of the motor. The simplest method to provide a variable power supply is by providing a variable series resistance between the […]

Stepper Motor Control, No Microcontroller Needed

Stepper motor is a simple way to make a motion control with high precision. A stepper motor control circuit is needed to make stepper motor works. A stepper motor controller usually use a microcontroller to make a complicated task. Some controller use stepper motor ic to simplify the circuit design.  For simple task like just […]

Two Wires-Stepper Motor Controller

To get a position control that are low cost, accurate and simple we can use stepper motor. To drive it we can use a circuit mounted close to the motor, and to control it we can use remote control circuit via long cable. The power for both motor and the driver circuit is carried over […]

Constant Speed PWM Motor Control

To make a constant speed motor control we can use Closed loop (servo) control. Constant speed motor is a motor that has constant speed although the load is change, indeed when the electric supply voltage is also changed. This circuit uses tachometer to sense the actual speed to maintain the speed at a constant value. […]

PWM Motor Speed Control Using Class D Audio Amplifier

This is class D audio amplifier circuit that is used to control PWM motor speed. This circuit has two advantages for battery-powered portable devices. First, this circuit produces much less power dissipation than do it’s linear cousins. Second, it enhances battery life. Here is the circuit: A potentiometer (R2) is used to generate a variable […]

L200 DC Motor Speed Control

This diagram tells us about how to use L200 device for the speed control of permanent magnet motors. By means of R1 and R2, we can obtain the desired speed, proportional to the voltage at the terminal of the motor. Vm= Vref (1+R2/R1) We can use this following equation to obtain better compensation of the […]

Speed-Control for Small Asynchronous Induction Motor

On the circuit diagram below show us a schematic which is used to set the speed of a low-power induction motor, such as those which can be found in fan applications. Noise coming from TRIAC commutations can be filtered using capacitors C1, C2 and C4. C2 has to be from X2 technology, whereas C1 and […]
