How to Make Simple DC Motor Speed Controller Circuit DIY | DIY DC Speed Controller

So we can control the speed of a DC motor by controlling the voltage at the gate terminal in the MOSFET IRFP450. To increase the DC motor speed, we have to increase the applied voltage at the gate terminal of the MOSFET IRFP450.

An increase in the PWM frequency results in an increase in the power loss of the H-bridge used with your Arduino microcontroller and may cause the motor driver board to overheat. Users will need a method of cooling down their H-bridge or motor driver to prevent the components from getting damaged.

A DC motor's speed is directly proportional to the input voltage. The higher the input voltage, the faster the output speed of the MOSFET. The lower the input voltage, the slower the output speed control system. We can control the speed independently of torque by manipulating the supply voltage controller system.

Brushless DC motors are an advanced option due to their wide speed range, low heat, and maintenance-free operation controller circuit. Stepper Motors offers high torque and a smooth low-speed operation system.

Compound DC Motors. Compound DC motors, or compound wound motors Control for MOSFET has both series and shunt field windings. These types of motors offer good starting torque, but they may have control problems in variable-speed drive for MOSFET IRFP450.
