Main performance indexes of driving motor

1 output current and voltage range. It determines the power that the circuit can drive the motor.

2. Efficiency. High efficiency not only means saving electricity, but also means reducing the heating of the driving circuit. In order to improve the efficiency of the circuit, we can start with ensuring the on-off state of power devices and preventing the * * * state from being turned on (a possible problem in H-bridge or push-pull circuit, in which two power devices are turned on at the same time, resulting in short circuit of power supply).

3. Influence on control input The power supply circuit should have good signal isolation at its input to prevent high voltage and high current from entering the main control circuit, which can be isolated by high input impedance or photoelectric coupler.

4. Impact on power supply. * * * state conduction will cause the power supply voltage to drop instantly and cause high-frequency power supply pollution, and large current may cause the ground potential to float.

5. Reliability. No matter what control signals and passive loads are added, the motor drive circuit should be as safe as possible.

I hope it helps you. I hope it can be adopted. Thank you!
