Description

This is circuit schematic diagram of Electronics Motor Controller Based on Transistor that can help you to build electronic motor controller. The main component in this circuit are transistors.

According Electronicsproject site that also published this circuit describe that the power supply is given by pressing switch SW1 it shots the N/O contact of relay RL­1 which gives supply to the circuit. The current through resistor R8 gives the base current to transistor T5. Where transistor T1, T2 and T3 from the over and under-voltage cut-offs. Here the transistor T4 on when over or under voltage is given to transistor T3.

For avoiding noise capacitor C2 with resistor R10 form a loss-pass filter and also give sufficient time delay. Here the resistor network (R11, R12, VR1) are used as current sensor. Where Diode D3 is as rectifier and capacitor C1 is used as noise filter of switching circuit.
