Abstract: This paper introduced the basic principles of the low-voltage asynchronous motor indirect vector control system based on TMS320LF2407, then on this basis, the structure and software design of the system was introduced briefly and the design of main hardware circuit was introduced in detail, such as current detection, short circuit protection and others. Finally, the experimental result on a low-voltage asynchronous motor indicated that the system is of good stability and good control performance. Key words: TMS320LF2407; low-voltage electric motor; indirect vector control
