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 used in 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. This solution uses 32-bit ARM/DSP as the main control chip; in order to reduce the complexity of the circuit and improve the reliability, the intelligent power module is used as the motor power drive part; this solution 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.
