![]() By it uses IC SG3526B control in the character PWM that receive like very much and drive motor with power Mosfet number IRFP7410 x 2 pcs. This is a 24V DC motor controller at the current 20Amp. The other parts, PCB, Heatsink, and more.Ģ4V Motor control with 20A Short Circuit Protection.IC1: TL494, Pulse width modulation(PWM).But it is a full article and not a clear photo. He said it is a very good high current DC motor controller. Pulse rising-edge and falling-edge at the gate of MOSFET: 1.5uS and 1.6uSįig:3 The components layout of this project. – Soft start: between 0 to 100% in range lower than 1 second – Adjusting pulse frequency: about 100Hz to 1.1 Khz(129 Hz to 1.28 Khz in this projects) – Cut off working when lower battery voltage: As setting at 11.5V for 12V and 23V for 24V battery. – There is over load current 15A or current limit with current flowing throw R11 and Q1 work to stop IC1 12V-24V PWM Motor controller circuit using TL494 and IRF1405įig:1 Schematic diagram of this projects. – For Control speed motor 12V 150Wmax 15A.
