Brushless DC motor control system for automobile air conditioner based on DSP

The invention provides a brushless DC motor control system for an automobile air conditioner based on a DSP. The device is characterized in that the device is characterized in that the system comprises a core control module and a brushless DC motor; the core control module is a TMS320LF2407A processor; the core control module is connected with a driving module; the driving module is connected witha three-phase full-bridge inversion module, and the three-phase full-bridge inversion module is connected with a power supply and the brushless DC motor; a serial port communication interface of thecore control module is connected with an upper computer, and a display interface of the core control module is connected with the display panel. Compared with the prior art, the control technology: the operation and stop and the operation direction of the motor can be controlled by switching on and off relative to a GND; system fault protection: when the system is under-voltage, over-current, over-temperature and locked-ro
