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 disk, or other type of disk. 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).
What is a motor driver
A motor driver is simply a switch, because the motor drives a large current or voltage, and when ordinary switches or electronic components cannot be used as switches to control the motor, a so-called driver must be added to control the motor.
The function of a motor driver: The function of a motor driver refers to controlling the idle speed of a motor by controlling the rotation angle and operating speed of the motor to achieve control over the duty cycle.
Principle circuit diagram of motor drive circuit: The motor drive circuit can be driven by relays or power transistors, or by thyristors or power type MOSFETs. In order to adapt to different control requirements (such as motor operating current, voltage, motor speed regulation, forward and reverse control of DC motors, etc.), different types of motor drive circuits must meet relevant requirements.
The electric vehicle does not start when powered on, making it difficult to push and accompanied by a “clacking” sound. The occurrence of this situation is caused by a short circuit in the motor wire due to virtual contact. It is difficult to remove the three coarse phase wires of the motor and push the cart, indicating that the controller is broken and needs to be replaced in a timely manner. If the implementation is still difficult, it indicates that there is a problem with the motor, which may be caused by a short circuit and burning of the motor coil.
