DC Motor Speed Controller
Vary the speed
of DC motors
the very best
way with this
kit. Gear boxes
can be costly
and series
resistors may
cause stalling.
This circuit delivers the voltage to the motor
with pulses and the speed is controlled via
pulse width modulation (PWM). The speed control is a potentiometer, for DC motors up to 100
Volts at a maximum of five amps.
