METHOD / ASSUMPTIONS

Twheel = (Frequired ÷ n) × (D ÷ 2)

Twheel: wheel torque, N·m
Frequired: rolling + slope + acceleration force, N
n: powered wheel count
D: effective wheel diameter, m

Model boundaries

The calculator does not prove that sufficient tire grip is available.
Efficiency allowance is not a gearbox ratio conversion.
Check motor thermal limits, controller current, voltage sag and duty cycle.

Engineering reference

Calculators and selection guidance are provided for preliminary design reference. Actual performance and safety depend on the complete system, operating environment and validation requirements.
