A motor (100) comprises a first rotating device (102), a second rotating device (120) and a brake assembly (140). The second rotating device is mounted on a common axis with the first rotating device and is matched with the first rotating device. The brake assembly is connected with the second rotating device to limit the rotation of the second rotating device. A stator in a conventional motor or generator is designed as a rotating stator which surrounds a rotor and is mounted on a common axis with the rotor, so that the rotating stator and the rotor can rotate in opposite directions to increase the interaction generated by the magnetic field and thereby promotes the efficiency of the motor. |
