Motor disassembly device for three-in-one electric drive system

The invention provides a motor disassembly device for a three-in-one electric drive system. The motor disassembly device for the three-in-one electric drive system comprises a working table (1), a clamping jaw (2), a pulley (3), a rotor fixing mechanism (4) and a rail seat (5), and the clamping jaw (2) is arranged on the working table (1) and used for fixing a speed reducer; the rail seat (5) is fixedly connected with the working table (1), and a sliding rail extending in the vertical direction is arranged on the rail seat (5); the pulley (3) is slidably connected with the sliding rail, and aconnecting part used for being fixedly connected with a stator of a motor is arranged on the pulley (3); and the rotor fixing mechanism (4) is used for pressing a rotor of the motor in the vertical direction. The motor disassembly device for the three-in-one electric drive system can prevent the stator and the rotor from being absorbed together due to deflection, so that the disassembly work is rapidly and stably complete
