Electric Motor Torque Calculator

Measuring the torque of the motor is a challenging task.

Electric motor torque calculator.

Calculators kw hp power torque hpl kw 3 phase mot. 98 83 nm the motor toque t in n m is calculated with the following equation. Efficiency of the motor is calculated as mechanical output power divided by electrical input power. 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.

The motors have enough torque and speed to do all kinds of experiments and calculations. Motor speed in rpm. 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. 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. N revolution per minute rpm alternatively. T inlb p hp 63025 n 1. Torque n m 9 5488 x power kw speed rpm power kw torque n m x speed rpm 9.

In the calculator above fla is rla 25. T ftlb torque lb f ft. How to calculate torque of motor. E p out p in.

Horse power and speed in rpm. Therefore we suggest calculating it. It requires special expensive equipment. T ftlb p hp 5252 n 1b.

1 hp 0 745 kw. The unit of torque is n m newton meter. Electrical motor power velocity and torque equations. T inlb torque in lb f.

P hp horsepower delivered by the electric motor hp. Rla running load amps current drawn during normal operation of electric motor. 1 ft lb f 1 356 nm. 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. In other words torque t n m is equal to the ratio between the electrical power p w in watts to the acceleration. Power torque torque lb in 63 025 x power hp speed rpm power hp torque lb in x speed rpm 63 025. Torque in imperial units can be calculated as.

Select the number of phases from the drop down list. The motor speed for ac motors can be caculated with the motor speed calculator. Related mobile apps from the engineering toolbox. This motor full load amperage fla calculator allows you to calculate the full load current of the ac electric motor.

These equations are for estimation only friction windage and other factors are not taken into consideration. T displaystyle frac 60 2 pi cdot displaystyle frac p cdot 1000 n parameters.
