In the calculator above fla is rla 25.
The motor speed for ac motors can be caculated with the motor speed calculator.
These equations are for estimation only friction windage and other factors are not taken into consideration.
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.

The following calculators compute the various torque aspects of motors.
Generally horsepower is a unit for measuring the power of various electrical motors piston engines steam turbines etc and it is equal to 746 watts or 33 0000 lb ft per.
Select the number of phases from the drop down list.
Motor speed in rpm.
Motor rating in kw.
This motor full load amperage fla calculator allows you to calculate the full load current of the ac electric motor.
It requires special expensive equipment.
The motors have enough torque and speed to do all kinds of experiments and calculations.
Therefore we suggest calculating it.
T ftlb torque lb f ft.
Torque is nothing but a momentary force developed at the time of force is applied to the motor.
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.
Efficiency of the motor is calculated as mechanical output power divided by electrical input power.
P hp horsepower delivered by the electric motor hp.
How to calculate torque of motor.
Rla running load amps current drawn during normal operation of electric motor.
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 unit of torque is n m newton meter.
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.
