An apparatus, system, and method are disclosed for an efficient hub motor. A stator is attached to a shaft. Coils are embedded in the stator in a circular pattern. Two rotors are rotatably coupled to the shaft with the stator between them. Permanent magnets are embedded in each rotor. Each permanent magnet and each core has a similar cross-sectional shape. The permanent magnets are positioned in a circular pattern corresponding to the coils. The permanent magnets are positioned so that when a coil aligns with a permanent magnet a next coil aligns between two magnets. Shorting bars connect exterior edges of the permanent magnets. A sequence control connects each coil so that current flows in a coil in one direction and the sequence control disconnects the coil and reconnects the coil with current flowing in the opposite direction in response to a set of permanent magnets aligning with a coil.
