High-performance drive solution based on ARM/DSP

Introduction

In recent years, variable frequency control has received widespread attention and application due to its energy saving, quiet and low vibration. The high-performance drive solution based on ARM/DSP provides high-performance and multi-control solutions for medium and large power three-phase motors. It is applied to occasions that require high performance and real-time performance of motor control, such as industrial sewing machines, CNC machine tools, white goods, industrial fans, etc. The program uses 32-bit ARM/DSP as the main control chip; in order to reduce the complexity of the circuit and improve reliability, the intelligent power module is used as the motor power drive part; the program integrates the current commonly used current detection circuit to adapt to different motors and Different control methods are required; at the same time, due to the high-performance MCU, more types of communication interfaces can be flexibly applied, such as: URAT, CAN, RJ45, etc.

The main motor types and control methods covered:

Higher value brought by high-performance motor control:

Variable speed control Sensorless control

Vector control Multi-axis control

Space vector PWM flexible communication interface

Higher motor efficiency Each controller can control more motors

Higher control efficiency and richer system functions

Higher power level efficiency, higher reliability and stability

Higher price, one platform can support more products
