PMSM-driven controller for pneumatic brake pump of oilless vortex air compressor of electric vehicle

The invention discloses a PMSM-driven controller for a pneumatic brake pump of an oilless vortex air compressor of an electric vehicle. The PMSM-driven controller comprises a controller body as well as a box and a mounting bracket which are matched, wherein the controller body is connected with the mounting bracket through a bolt; a transformer isolated power supply is arranged inside the controller body; the transformer isolated power supply is electrically connected with an MCU controller, a DSP28027 driver and a PWM drive module; the MCU controller is in signal connection with a communication module RS485/CAN and the DSP28027 driver; the MCU controller is used for acquiring and controlling signal pressure and a temperature, and monitoring and controlling a radiating fan; and the DSP28027 driver is in input connection with a low-temperature heating module, a voltage detecting module and a three-phase current sampling module. The PMSM-driven controller can achieve a special, compact and protective-level high
