Problems solved by technology

Therefore, the heat dissipation effect is affected
prevents the motor from operating to its full potential at high loads
At the same time, the general motor has only one efficiency point, and the motor has no more energy-saving options under different operating conditions

Abstract

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.

Description

technical field [0001] The invention relates to a novel inner rotor permanent magnet hub motor for an electric power-assisted vehicle. Background technique [0002] The motors used in power-assisted electric bicycles are classified according to their location and are divided into front-wheel motors, rear-wheel motors, mid-mounted motors, and side-mounted motors. [0003] So far, the front wheel and rear wheel hub permanent magnet motors of electric bicycles are all external rotor motors without exception. The stator is fixed on the vehicle frame by the shaft inside, and the rotor is outside, and the linked shell drives the wheel to rotate through the spokes. But there is an inherent limitation in this type of motor, that is, the heat dissipation of the motor is poor. Since the motor winding is included, the heat generated by the winding can only be dissipated through the shaft or first through the air and then through the housing. Therefore, the heat dissipation effect is...
