Product test report E.g. 72V 8000W
From the test report, we could find expected max rpm is 1253.7, max torque is more than 122.0N.m, which performance well on EFF(Reach 87.7%).
From the test report, we could find expected max rpm is 1503.5, max torque is more than 153.0N.m, which performance well on EFF(Reach 85.5%).
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. 273 spoke motor)
It’s 273 spoke motor, the dimension of shaft/axle could be customized according to your requirements, such as the length
between fork could customized to be 200mm. For more testing report and CAD drawings, please contact with us by email or trademanager freely.
