A brushless DC motor driver is a semiconductor device that drives and controls a motor by receiving instructions from a microcontroller or other control unit.
Since the control of brushless DC motors is very complex, it is possible to create a drive circuit using semiconductor discrete components, but this would require numerous parts and would also complicate software control.
Therefore, motor drivers are often used to reduce the software development load and the number of components.
Brushless DC motor drivers are essential for devices.
Since brushless DC motor drivers can accurately control the speed of brushless DC motors, they are used in hard disks, NC-controlled machines, automobiles, hybrid vehicles, etc. In particular, brushless DC motor drivers are used in automobiles for door locks.
In particular, brushless DC motors are used in automobiles for door lock motors, electric power steering motors, headlight optical axis drive motors, and many other applications.
Motor drivers are semiconductor devices that receive instructions from a microcontroller or other computer control unit to drive and control motors.
Although a microcontroller is a necessary device to control the timing and speed of motor rotation and drive, most microcontrollers do not have the drive capability to rotate and drive motors directly from their input/output ports.
In this case, a motor driver can drive the motor by providing the signals to control between the microcontroller and the motor instead.
Since the electromagnets are fixed in the motor, changing the direction of the current flowing through the coil determines the polarity of the electromagnets and whether they "attract or repel" each other.
When the motor receives a signal from the motor driver, it changes the polarity of each electromagnet to move the motor.
Advantages of using a motor driver include abundant on-chip protection functions, reduced labour hours required to create microcontroller control software, reduced number of components, minimized board mounting area, and easy motor driving.
