The invention discloses an integrated
electric drive system for an electric
loader and a control method of the integrated
electric drive system, a high-speed
permanent magnet synchronous motor and a controller thereof, and a low-speed motor and a controller thereof are integrated into the integrated
electric drive system, and the rear end of the integrated electric drive system extends out of a
motor shaft to be connected with a
hydraulic pump. Two motor shafts extend out of the front end and are connected with the gearbox in parallel, torque and rotating speed are output through a front
flange and a rear
flange of the gearbox after the motor shafts are coupled in the gearbox, and front and rear axle driving of the electric
loader is achieved. Two rotation speed ratios can be achieved, the output torque is large, the system efficiency is high, the size is small, the weight is light, the reliability is high, and meanwhile when a high-speed walking motor shifts gears, the output torque and gear shifting power of a low-speed upload motor are not interrupted; six
modes can be switched, the two motors are cooperatively controlled according to the power requirements of different working conditions of the
loader, and the gear shifting smoothness, the system efficiency and the whole vehicle cruising ability can be improved.
