Abstract: A composite material permanent magnet synchronous electric motor includes a composite material shell; a permanent magnet outer rotor is disposed in the composite material shell; a stator is disposed in the permanent magnet outer rotor in a penetrating manner; and air gaps are disposed in gaps between the stator and the composite material shell and between the stator and the permanent magnet outer rotor in a one-to-one correspondence manner. The composite material permanent magnet synchronous motor improves an output torque of a motor with a same power, improves a power-to-weight ratio of the electric motor, and improves a power density; and by means of using composite materials, weights of the permanent magnet synchronous motor are reduced, and a mechanical strength thereof is improved.
