What is a motor driver

Drivers are used in many places, but they are a holistic concept. Simply put, a driver is the hardware that drives a certain type of device. For example, drivers are used on computers and other industrial equipment or tools. This article focuses on what a driver is and what a motor driver is.

What is a driver

Driver broadly refers to the hardware that drives a certain type of device. In the field of computer science, a drive refers to a disk drive. A storage area formatted with a drive letter through a file system. The storage area can be a floppy disk CD、 Hard drives or other types of disks. Click on the corresponding icon in Windows Explorer or My Computer to view the detailed contents of the drive.

The driver is located in the middle of the main control box (Main Controller) ->Driver ->Motor during the entire control process. The main function of the driver is to receive signals from the main control box (NC CARD),

process the signals, and then transfer them to the motor and the sensors related to the motor, and feedback the working condition of the motor to the main control box (Main Controller).
