The 36V 250W electric bicycle motor is widely used in electric bicycles because it has the following advantages over traditional motor.

(1) 36V 250W electric bicycle motor has long life, maintenance-free, high reliability. In the brush DC motor, because the motor speed is higher, brush and commutator wear faster, general work about 1000 hours to replace the brush. In addition, the technical difficulty of the reduction gear box, especially the lubrication problem of the transmission gear, is a big problem in the current brush scheme. So there are brush motor noise, low efficiency, easy to produce problems such as failure. So the advantages of DC motor are clear.

(2)36V 250W electric bicycle motor has high efficiency and energy saving. Generally speaking, the efficiency can be higher than 85% because the DC motor has no wear and tear of mechanical commutation and the consumption of gear box, as well as the loss of speed control circuit, but considering the best performance-price ratio in practical design, in order to reduce material consumption, the general design is 76% . The efficiency of the DC motor is usually around 70% due to the consumption of the gearbox and the overrunning clutch.
