This PWM 20A DC Motor Speed Control is designed as a Mini Style DC Motor Speed Controller. This speed controller is used to control the speed of the DC motor by adjusting pulse-width-modulated  DC voltage. It provides a DC voltage with a Duty Cycle fully adjustable from 10%-100%. The motor speed controller can provide a continuous current of 0-20A to your DC motor or other DC load.  PWM-controlled DC motor is a high efficiency, high torque method to control the speed of a Dc motor by generating low heat.

This module ensures reverse polarity protection and makes its application in the field of industrial production. These modules consist of imported filtering capacitance, field-effect power transistor, and specified motor speed regulator driver IC. And also the output power supply is adjusted using the potentiometer. This circuit also consists of a 20A fuse, with a reverse connection of the power supply and control voltage over-voltage protection function.

Pulse-width modulation (PWM) or duty-cycle variation methods are commonly used in the speed control of DC motors. The duty cycle is defined as the percentage of digital ‘high’ to digital ‘low’ in addition to digital ‘high’ pulse-width during a PWM period.  This is defined as a great method of controlling the amount of power delivered to a load without dissipating any wasted power. The motor can be positive or negative, when the direction of operation and expectations do not match, you can adjust the line order to change the direction.
