Problems solved by technology

The magnetic steel material is a rare metal in my country, and the storage capacity is very small. In order to control the use of rare metals, the country restricts the mining of rare metals, which causes the price of magnetic steel to increase.
The original magnetic steel on the motor hub needs to cover the entire inner ring of the hub, thus requiring a large amount of magnetic steel, resulting in an increase in production costs

Abstract

The invention provides a rear wheel of a direct-current brushless permanent-magnet motor, belonging to the field of mechanical technology. The invention solves the problems that the current rear wheel of the direct-current brushless permanent-magnet motor is inconvenient to install, and the cost is high. The rear wheel of the direct-current brushless permanent-magnet motor comprises a wheel hub. A ring-shaped fixed strip is fixedly connected to the wheel hub, a plurality of mounting holes are evenly distributed on the fixed strip, each mounting hole is internally provided with a magnetic steel, and between two adjacent magnetic steels is a gap. The rear wheel of the direct-current brushless permanent-magnet motor has the advantages of being convenient in installation and low in productioncost.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a rear wheel, in particular to a DC brushless permanent magnet motor rear wheel on an electric bicycle. Background technique [0002] The DC brushless permanent magnet motor utilizes the cutting of the permanent magnet constant magnetic field and the electromagnetic variable magnetic field, and the control commutation system composed of the magnetic induction sensor to collect the signal of the permanent magnet and electronic components is realized by the electromagnetic field A, B, C three-phase switching power supply Its operation is a key component of electric vehicles such as electric cars and electric bicycles. [0003] The DC brushless permanent magnet motor used in electric bicycles generally includes a stator and a rotor, wherein the rotor is composed of a hub, and the inner ring of the hub is covered with magnetic steel. Magnets are magnetic materials with high magnetic ...
