Abstract

The invention discloses a motor used for an electric bicycle. The motor comprises a central shaft, a silicon-steel sheet disposed outside the central shaft, a plurality of silicon-steel sheet grooves disposed on the silicon-steel sheet, magnetic pole pairs sleeved outside the silicon-steel sheet, a cylinder disposed outside the magnetic pole pairs, and a power line connected with the central shaft. A diameter of the silicon-steel sheet is 70-180mm. The motor is characterized by simple structure and convenient installation, and operating requirements of a small wheel bicycle are met. The motor can satisfy electric bicycle requirements of different types and sizes, and prolongs service life of the electric bicycle motor.

Description

Technical field: [0001] The invention relates to a motor, in particular to a motor for an electric vehicle. Background technique: [0002] At present, electric vehicles have become an indispensable means of transportation for people, but most of the current electric vehicles use brush motors, disc motors or printing plate motors. These types of motor carbon brushes are easy to wear and need to be adjusted through gears. The number of revolutions, the service life shown is short, and the usage is not ideal. Invention content: [0003] The purpose of the present invention is to overcome the above disadvantages and provide a motor for electric vehicles with good wear resistance and long service life. [0004] The purpose of the present invention is achieved through the following technical solutions: a motor for electric vehicles, including a central shaft, a silicon steel sheet is sheathed on the periphery of the central shaft, and a plurality of silicon steel sheet grooves ...
