This document discusses using a chopper circuit to control the speed of a DC motor. A chopper circuit allows controlling the voltage to the motor by rapidly switching the voltage on and off, which enables remote speed control. This method improves motor efficiency by reducing current, lowers temperatures, shrinks motor size, and increases lifetime compared to previous variable resistor and transformer-based speed control methods. The project will use buttons to vary the firing angle of a MOSFET in the chopper circuit to control motor speed, with lower firing angles providing higher speeds.
