Production Pictures& Details
Product Test Report& CAD Drawing
From 1st test report, we could find expected max rpm is 1029.9, max torque is more than 143.9N. M, which performance well on EFF(Reach 88.7%).
From 2nd test report, we could find expected max rpm is 845.3, max torque is 146.4 N. M, which performance well on EFF(Reach 88.9%).
For the speed
There is two formulas, Speed(km/h)=0.9*RPM(r/min)*2r π(m)*60
Power= Torque*RPM/9.55
So under the same power, the faster the RPM/speed is, the smaller the torque.
For hills climbing: High torque and low RPM/speed motor maybe suitable.
P. S.: Above speed is calculate due tolead-acidbatterytheoretically, if it's lithium battery, the speed maybe 5kph more.
In practice, the speed will changeaccording to weight of loading &vehicle,
Road situation, tyre models and windresistance.
