Electric Motor Torque Calculator

In other words torque t n m is equal to the ratio between the electrical power p w in watts to the acceleration.

Electric motor torque calculator.

1 hp 0 745 kw. T inlb p hp 63025 n 1. These equations are for estimation only friction windage and other factors are not taken into consideration. Torque in imperial units can be calculated as.

When determining the torque requirements for a electric motor consideration should be given to the load and start time demands during the start duration operating torque and peak load torque. Torque refers to the rotational effect produced when force is applied to an object and is measured in newton meter n m in metric system or pound feet in u s. Torque is a rotational force generated by the electrical system whereas the horsepower is an imperial unit of power equal to 745 7 watts. T displaystyle frac 60 2 pi cdot displaystyle frac p cdot 1000 n parameters.

T ftlb p hp 5252 n 1b. It requires special expensive equipment. The motors have enough torque and speed to do all kinds of experiments and calculations. Start and running torque requirements calculations for electric motors.

How to calculate torque of motor. Rla running load amps current drawn during normal operation of electric motor. 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. P hp horsepower delivered by the electric motor hp.

Motor rating in kw. Motor speed in rpm. Related mobile apps from the engineering toolbox. Industrial electric motor application design industrial electric motor supply.

The unit of torque is n m newton meter. Electrical energy measured in watts can be used to produce torque and an electric motor is a good example of electrical energy that can produce. Torque is nothing but a momentary force developed at the time of force is applied to the motor. Torque horsepower hp conversion is a method of converting one unit from other and vice versa.

Measuring the torque of the motor is a challenging task. 98 83 nm the motor toque t in n m is calculated with the following equation. T inlb torque in lb f. E p out p in.

Horse power and speed in rpm. N revolution per minute rpm alternatively. The following calculators compute the various torque aspects of motors. The motor speed for ac motors can be caculated with the motor speed calculator.

Electrical motor power velocity and torque equations. Torque to horsepower hp conversion formula horsepower hp to torque conversion formula. Therefore we suggest calculating it. T ftlb torque lb f ft.

Efficiency of the motor is calculated as mechanical output power divided by electrical input power. In the calculator above fla is rla 25.
