![]() In Figure 6 circuit, if we apply power to A-point. SCR DC motor speed control circuit using IC-CMOS.Simple 12V | 9V | 6V Motor DC Speed Control with PWM mode.12V-24V PWM Motor controller circuit using TL494-IRF1405.Figure 5: we use the four transistors as a switch controller.Īnd add a diode to protect the electricity that may flow backward from the motor. Read Also: Many about transistor driver circuits Bridge transistor Motor driverĪs Figure 5, we use the four transistors to connected into the H-bridge circuit. It causes the transistor running and the DC motor will rotate, too. When a base of transistors gets the current electricity. ![]() You see in Figure 4.įigure 4 Using the transistor as switches. We will try to use all the transistors as the switch. Recommended: Learn transistor circuit works here Start to apply transistors Figure 3: Both switch-S2 and S4 are closed, causes DC motor rotates back in counter-clockwise direction.īecause that current will flow through the negative of motor cause current reversed or Rotated back counter-clockwise direction. ![]()
