How to choose a motor driver？

Micro motors can be used in various application systems in various fields. Moreover, there are many types of motors, and relatively speaking, there are also many driving methods and control methods for the motors. The following Vshida micro motor will introduce to you how to choose a motor driver.

1、Minimal power usage, high effectiveness
Low power consumption power components and driving technologies are necessary to lower the motor's power consumption. For instance, very high efficiency can be achieved in a wide range of rotation speeds, from low-speed rotation to high-speed rotation, by using the automatic lead angle adjustment feature, etc.

2 Quiet, little vibration
The drive waveform must be optimized to reduce noise and vibration during motor operation. According to the use in each field, this necessitates choosing the most appropriate excitation drive technology for diverse motor magnetic circuits. For instance, the fan motor driver's soft start technology, the stepper motor driver's current attenuation technique, the suitable excitation mode of the brushless DC motor driver (120 degrees, 150 degrees, sine wave), etc.

3 High reliability
The motor driver must have enough protective features, such as a function to avoid malfunction due to power supply voltage drop, in order to safeguard the motor driver IC from aberrant voltage and current. To further ensure safety, a function to output fault status to an external host processor is needed, as well as a current limit function to manage the motor current when the motor is started or forced to stop and stalled.

4、Control and practicality
For the creation of high-performance motor application systems, high-efficiency drive control algorithms, such as the high-precision positioning control technology required by actuators, and motor digital rotation control technology through speed control and phase control are essential. Convenience is increased by driver IC compatibility. It is also crucial to increase convenience so that it may be replaced without altering the motor drive control board's mode during development when the specification changes.
