Torque is nothing but a momentary force developed at the time of force is applied to the motor.
Electric motor torque calculator.
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.
The unit of torque is n m newton meter.
The motor speed for ac motors can be caculated with the motor speed calculator.
Torque in imperial units can be calculated as.
Horse power and speed in rpm.
Power torque torque lb in 63 025 x power hp speed rpm power hp torque lb in x speed rpm 63 025.
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.
This motor full load amperage fla calculator allows you to calculate the full load current of the ac electric motor.
Efficiency of the motor is calculated as mechanical output power divided by electrical input power.
