** Future Kit needs to be assembled **


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.


Technical data

- 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


Circuit performances

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.
