The invention provides a novel inner rotor permanent magnet hub motor for a moped scooter. The novel inner rotor permanent magnet hub motor is characterized in that a left permanent magnet hub motor electromagnetic structure A and a right permanent magnet hub motor electromagnetic structure B are arranged on the left side and the right side of a motor shaft respectively and isolated by an outer shell support, the outer shell support is fixedly connected with the motor shaft, a motor outer shell is fixedly connected with the outer shell support, a motor stator is fixedly connected with the motor outer shell, a motor rotor and a hub are fixed, the hub is installed between the motor shaft and the motor outer shell through a bearing, the hub is connected with a disc-shaped shaft surface, a plurality of holes are formed in the periphery of the shaft surface to be connected with spokes of a bicycle, the rotor rotates to drive the hub to rotate, the hub rotates to drive the shaft surface to rotate, and the spokes of wheels of the bicycle are accordingly driven to rotate. The novel inner rotor permanent magnet hub motor has the advantages that the radiating effect of the motor is good, and large power loads can be borne; meanwhile, the one motor can be selected for working, or two motors can be selected for simultaneous work, and power selection space is large.
