What Is A Motor Driver?

The motor driver is a controller used to control the motor and is a part of the motor system. It is a way to control the idle speed of the motor by controlling the rotation angle and running speed of the motor to realize the control of the duty cycle.

A motor drive is an electromagnetic device that converts or transfers electrical energy, or converts one form of electrical energy into another, according to the laws of electromagnetic induction.

1. The range of output current and voltage determines how much power the circuit can drive the motor.

2. Efficiency. High efficiency not only means saving power, but also reducing heat generation in the drive circuit. In order to improve the efficiency of the circuit, it is necessary to ensure the switching state of the power devices and prevent common-state conduction (a possible problem with H-bridge or push-pull circuits, that is, two power devices can be turned on at the same time to short-circuit the power supply).

3. Effect on control input. The input end of the power supply circuit should have good signal isolation to prevent high voltage and current from entering the main control circuit, which can be realized by using high input impedance or optocoupler.

4. Impact on power supply. Common-state conduction can cause a momentary drop in the power supply voltage to cause high-frequency power supply pollution. Large currents may cause ground potential fluctuations.

5. Reliability. No matter what control signal or passive load is added, the motor drive circuit should be as safe as possible.
