Where:
T= Motor torque in lb/inches
R = Overall gear reduction including both axle and transmission
r = Rolling radius of loaded driving tyre in inches.
Example:
Find the tractive effort where the rolling radius of driving tyres is
15 inches, the total ratio of power train is 10, the motor torque is 1000
lb in.
Where:
T= Motor torque in kg/millimetres
R = Overall gear reduction including both axle and transmission
r = Rolling radius of loaded driving tyre in millimetres
Example:
Find the tractive effort where the rolling radius of driving tyres is
400 millimetres, the total ratio of power train is 10, the motor torque
is 115 N m
