Product test report

1. E.g. 48V 3000W High Torque 

 

 

From the test report, we could find expected max rpm is 289.5, max torque is 178.9, which performance well on EFF(Reach 88.7%). 

 

2. E.g. 72V 3000W High RPM

 

 

 

 From the test report, we could find expected max rpm is 921.2, max torque is 145.8, which performance well on EFF(Reach 88.0%). 

 

For the speed, there is two formulas,

 

Speed(km/h)=0.9*RPM(r/min)*2r π (m)*60     Power= Torque*RPM/9.565

 

So under the same power, the faster the RPM/speed is, the smaller the torque.

 

For hills climbing, high torque, low RPM/speed motor maybe suitable. 

 

 

 

P.S.: Above speed is calculate due to leadacid battery theoretically, if it’s lithium battery, the speed maybe 5kph more.   

 

In practice, the speed will rang according to weight of loading & vehicle, road situation, tyre models and wind resistance

 

 

CAD Drawing (e.g. 205 spoke motor)  

 

It205 spoke motor, the dimension of shaft/axle could be customized according to your requirements, such as the length 

between fork could customized to be 150mm to 200mm. For more testing report and CAD drawings, please contact with us by email or trademanager freely. 

Were glad at your service. : )
