The distributed power wheel drive system changes the central motor centralized drive method used in the past of new energy vehicles, and is directly driven by two permanent magnet wheel motors installed on both sides of the axle of electric vehicles. Among them, the rated power, speed, torque and other technical indicators of the permanent magnet motor are excellent, the maximum efficiency can reach 96%, and the output frequency of the motor controller is as high as 600Hz, which improves the stability and comfort of the operation of electric vehicles.
