Abstract

The invention discloses a screw permanent-magnet frequency-conversion wind source device special for a new-energy electric vehicle. The integrated all-in-one wind source device comprises an inlet valve, an air suction pipe, an escape pipe, a cooler and a spiral main engine. The inlet valve intakes air into the spiral main engine for compression through the air suction pipe. The integrated all-in-one wind source device further comprises an oil fine separating box. The escape pipe is communicated with the oil fine separating box. The compressed air enters the cooler for cooling after passing through the oil fine separating box, and then the compressed air is exhausted from the escape pipe for a new-energy vehicle system to use. The integrated all-in-one wind source device further comprises a permanent-magnet motor. The permanent-magnet motor drives the spiral main engine to rotate. The integrated all-in-one wind source device further comprises a frequency-conversion control system. The frequency-conversion control system controls the permanent-magnet motor to work. According to the screw permanent-magnet frequency-conversion wind source device special for the new-energy electric vehicle, the motor working efficiency is changed through a frequency-conversion system to control torques of the motor at different rotating speeds, the vehicle power supply voltage is provided according to the actual need of the motor, and therefore the screw permanent-magnet frequency-conversion wind source device special for the new-energy electric vehicle has the advantages of being revolutionary, creative and energy-saving.

Description

technical field [0001] The invention relates to a special-purpose screw permanent magnet frequency conversion air source device for new energy electric vehicles. Background technique [0002] Without environmental protection, there will be no future for the automobile industry.
