A pulse width modulator(PWM) is a device that may be used as an efficient light dimmer orDCmotor speed controller. The circuit described here is a general purpose device thatcancontrol DC devices which draw up to a few amps of current. The circuit may be used in 12 Volt and 24 Volt s...
This circuit is designed as per a request made by Mr Vinoth from India. His requirement was a 12V/5A DC fan motor controller. I think this circuit is sufficient for this purpose. Quad 2 input Schmitt trigger IC CD4093 is the heart of this circuit. Out of the four Schmitt triggers ins...

try reducing the PWM frequency to the lowest possible value (usually about 25Hz) and work up towards the maximum of the motor controller. Choose the frequency that provides the best balance of torque throughout the desired speed range while balancing the motor chatter that can happen at lower ...
