Motor Drive Solution Based on GD32 MCU
As the electrical energy conversion unit connecting the battery and the motor, motor controller is the core of the motor driver and control system. The continuously growing market demand has led to higher requirements for motor drive technology and controller performance. Firstly, the digitization of motor systems is an inevitable trend. Leveraging high-performance, high-speed processors, motor drive control systems can implement complex and variable control algorithms that enhance motor efficiency. Secondly, the lightweight and integration of motor system is also a trend. In terms of the controller, the integration of power devices, drives, controls, sensors, and power supplies not only reduces the size, but also helps to improve the motor system efficiency and reduce power loss.GigaDevice has launched a variety of motor drive platforms for this market. For example, GD32E230C-FOC adopts the chip GD32E230C8T6 featuring Cortex®-M23 core as the main MCU and the GD30DR8306 as the driver chip to enable the implementation of the motor driver solution.
