How to choose the suitable motor for your e rickshaw?
Rickshaws are a part of life across much of Asia for tourists and locals alike. However, the gasoline-powered versions of these three wheel rickshaw are rarely environmentally friendly, creating smog and noise-pollution. Chinese company Beijing ERichman Technology CO., LTD has developed a new, electric rickshaw it hopes will improve environmental degradation and save on fuel costs for drivers.
For example, in India the model below is very popular in India
Normally, this kind of e rickshaw can use 6–8 years in India, Nepal. But in India, Nepal it is different situation.
For e rickshaw motor, it can use 3–4 years before you repair it. You need to regular maintenance for the motor.
You need to exchange motor oil: 85w/90 regularly.
First time, you need to exchange the motor oil two months after you begin to use the motor.
Second time, you need to exchange the motor oil six months after the last time. It is roughly 5000km, but if you use the motor too much , you need to shorten the maintenance time.
Beijing ERichman Technology CO., LTD is professional Professional E rickshaw spare parts supplier. We know the India, Nepal market very well. So the motor, which is one of the most important parts in the e rickshaw, we need to find the suitable model.
Nowadays, a few models motor on the market. 48v 800w brushless motor (40H), 48v 850w brushless motor (40H), 48v 900w brushless motor (45H), 48v 1000w brushless motor (50H). They are all 120 open style motor. They can be suitable for the normal differential in the market. Like 33 inch, 35 inch CY differential. Beijing ERichman Technology CO., LTD also supply high quality differential, can also accept OEM service.
But which motor is suitable for India market, which motor is suitable for Nepal market? This is a very serious question.
Before saying this, I want to clear some thing about the 48v 800w motor, and 48v 850w motor.
In India market, there’re two similar motor, 800w motor and 850w motor, but if you weigh them. You will found the weight is nearly the same. Because someone is selling the 800w motor, which marked 850w on the surface. It is a very smart business strategy. But I only want to tell you, it is still 800w motor, not real 850w motor.
Let’s go back to the First question. Which motor is suitable for India market. In North of India, the road is good, so 800w motor, 800w motor is already suitable for the road. If you really want the e richshaw to have perfect performance, you can choose 1000w motor. For Nepal, there’s too much Mountain roads and steep slope. So you need to use big motor on the rickshaw in Nepal. Like 1000w motor, 1200w motor, 1500w motor.
For motor quality, you need to check the cooper weight inside the motor, and workmanship of the cooper wires, whole appearance, whole weight of brushless motor, wires thickness, also check the plug, to confirm whether it is water-proof.
Also, for India Icat certificate request, max power must be lower than 2000w. This is one important point.
We can modify the controller max current to limit this max power.
In the next time, we will talk about the controller for this kind of brushless motor..
