Different structure of 36V 250W rear hub motor electric bicycle conversion kit
Jan 12, 2019

The motor power system of the 36V 250W rear hub motor electric bicycle conversion kit is mainly composed of an electric motor, a speed reduction mechanism, a brake and a heat dissipation system. The hub motor power system is mainly divided into two types according to the rotor type of the motor: an inner rotor type and an outer rotor type.

 

36V 250W rear hub motor electric bicycle conversion kit The drive motor of the motor system can be divided into two types: radial magnetic field and axial magnetic field according to the type of motor magnetic field. The main difference between the two is that the structure of the axial flux motor is more conducive to heat dissipation, and its stator can not need iron core; the force of the radial flux motor between the stator and the rotor is relatively balanced, and the magnetic routing silicon steel sheet is laminated, The technology is simpler and more mature.

 

At the same time, the 36V 250W rear hub motor electric bicycle conversion kit is composed of three types: permanent magnet, induction and switched reluctance. The induction motor has the advantages of simple structure, sturdy and durable, low cost, reliable operation, small torque ripple, low noise, no position sensor and high speed limit. The brushless permanent magnet synchronous motor can adopt cylindrical radial magnetic field structure or disc axial direction. The magnetic field structure has high power density and efficiency and wide speed regulation range, and has a broad development prospect. The switched reluctance motor has the characteristics of simple structure, low manufacturing cost and good speed/torque characteristics, and is mostly used in electric vehicles. drive.
