This is 12V DC motor speed control PWM circuit. Which using a TL494 (Switchmode Pulse Width Modulation Control IC) is base for control DC Motor with pulse.
Please detail more:
– For Control speed motor 12V 150Wmax 15A.
– R6 adjust speed motor.
– Driver Motor by Mosfet IRFZ48.x 2pcs.
– Control at Frequency 100HZ
– Adjust PWM duty cycle From 0 to 100%
– Rise and fall time = 10uS
– There is over load current 15A or current limit with current flowing throw R11 and Q1 work to stop IC1
