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

Torque n m 9 5488 x power kw speed rpm power kw torque n m x speed rpm 9. 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. In other words torque t n m is equal to the ratio between the electrical power p w in watts to the acceleration. T displaystyle frac 60 2 pi cdot displaystyle frac p cdot 1000 n parameters.

Horse power and speed in rpm. P hp horsepower delivered by the electric motor hp. Motor speed in rpm. 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.

In the calculator above fla is rla 25. 1 ft lb f 1 356 nm. T inlb torque in lb f. How to calculate torque of motor.

Electrical motor power velocity and torque equations. 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 motors have enough torque and speed to do all kinds of experiments and calculations. The motor speed for ac motors can be caculated with the motor speed calculator.

Torque in imperial units can be calculated as. These equations are for estimation only friction windage and other factors are not taken into consideration. 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. 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. It requires special expensive equipment. Torque is nothing but a momentary force developed at the time of force is applied to the motor. 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 ftlb torque lb f ft. Motor rating in kw. The following calculators compute the various torque aspects of motors.
