This is a revolution-per-minute control circuit of a DC
motor. The control is composed of a volume pot that can be
calibrated from zero to full load.
- Power supply : 12VDC
- Maximum output : 1.5A
- The Pulse Width Modulation (PWM) signal is sent from
point OUT to control the motor.
- IC board dimension : 1.76 in x 1.32 in
IC1 generates the frequency of about 264 Hz with respect
to the values of R1, R2 and R3 VR1 and C1 whereas VR1
adjusts the duty mode as desired. If the positive duty is greater
than the negative one, then the motor revolves slower. The
derived frequency will be sent from Leg 3 of the IC passing
through Leg B of TR1 which works under control at VR1.
