PWM motor control
Pulse width modulation (PWM) is Ideal for controlling small electric PCB drills that draw currents of up to 2 A. Larger currents are posstble if T2 gets addtional cooling and the value of C2 is increased. The design also makes use of the fact that the drill works with a small d.c. motor whose rotary speed is a function of the voltage across it.
