72V Brushless 3000W Electric Tricycle Hub Motor

72V Brushless 3000W Electric Tricycle Hub Motor

1. Design: Brushless DC Hub Motor
2. Volt & Power: 48V-144V, 350W-10000W
3. Speed: 30km/h-120km/h
4. Torque: 70N. M-350N. M
5. Efficiency: 85%-93%
6. Size: 10inch-16inch(e-scooter), 16inch-20inch(e-bicycle)
7. Two halls (one for spare)

From 1st test report, we could find expected max rpm is 854.3, max torque is more than 146.4N. M, which performance well on EFF(Reach 88.9%).
From 2nd test report, we could find expected max rpm is 518.3, max torque is 70.9 N. M, which performance well on EFF(Reach 85.7%).

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 to lead-acid battery theoretically, if it's lithium battery, the speed maybe 5kph more.
In practice, the speed will change according to weight of loading & vehicle,
Road situation, tyre models and wind resistance.
