How to calculate torque of 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. P hp horsepower delivered by the electric motor hp. In the calculator above fla is rla 25.

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. Electrical motor power velocity and torque equations. 98 83 nm the motor toque t in n m is calculated with the following equation. Enter the motor rated voltage in volts v enter the motor power rating and select the appropriate unit hp or kw enter the power factor and efficiency of the.

Efficiency of the motor is calculated as mechanical output power divided by electrical input power. T displaystyle frac 60 2 pi cdot displaystyle frac p cdot 1000 n parameters. 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. 1 hp 0 745 kw.

It requires special expensive equipment. The following calculators compute the various torque aspects of motors. Horse power and speed in rpm. Motor rating in kw.

Torque in imperial units can be calculated as. N revolution per minute rpm alternatively. T inlb p hp 63025 n 1. T ftlb p hp 5252 n 1b.

The motor speed for ac motors can be caculated with the motor speed calculator. Measuring the torque of the motor is a challenging task. 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. Torque is nothing but a momentary force developed at the time of force is applied to the motor.

Power torque torque lb in 63 025 x power hp speed rpm power hp torque lb in x speed rpm 63 025. Therefore we suggest calculating it. In other words torque t n m is equal to the ratio between the electrical power p w in watts to the acceleration. Calculators kw hp power torque hpl kw 3 phase mot.
