Measuring the torque of the motor is a challenging task.
Electric motor torque calculator.
Fla full load amps amount of current drawn when full load torque and horsepower is reached for the motor fla is usually determined in laboratory tests note.
The motor speed for ac motors can be caculated with the motor speed calculator.
In the calculator above fla is rla 25.
Efficiency of the motor is calculated as mechanical output power divided by electrical input power.

This calculator can be used to estimate the motor size and gear ratio when building or modifying electric scooters bikes go karts and other types of electric vehicles.
Torque is nothing but a momentary force developed at the time of force is applied to the motor.
How to calculate torque of motor.
Motor speed in rpm.
Electric motors produce a high amount of torque under load so for example an electric scooter bike or go kart with a 500 watt motor and one rider could be geared to go 20.
Horsepower to torque converter is an online tool used in electrical engineering to calculate how much torque will be generated according to the input power value either in horsepower or watts.
