__kV to Torque Formula:__

The kV to torque formula provides a way to calculate the torque generated by an electric motor based on its KV rating (RPM per Volt), the current it draws, and its rotational speed.

The kV to torque, T_{kV(N.m)} in Newton metres is calculated by dividing the product of motor kV rating, kV_{(RPM/V)} in RPM per Volt, which is a constant, current, I_{(A)} in Amperes and 1000 by the product of 2pi and rotational speed, RPM in revolution per minute.

The kV to torque, T_{kV(N.m)} = (kV_{(RPM/V)} * I_{(A)} * 1000) / ( 2 * pi * RPM)

T_{kV(N.m)} = kV to torque in Newton metres, N.m.

kV_{(RPM/V)} = motor kV rating in RPM per Volt,

I_{(A)} = current in Amperes, I_{(A)}.

RPM = rotational speed in revolution per minute.

1. Consider an electric motor with a KV rating of 200 RPM/V, drawing a current of 10 Amperes, and operating at 4000 RPM. Calculate the torque output of the motor.

Given: kV_{(RPM/V)} = 200RPM/V, I_{(A)} = 10A, RPM = 4000

The kV to torque, T_{kV(N.m)} = (kV_{(RPM/V)} * I_{(A)} * 1000) / ( 2 * pi * RPM)

T_{kV(N.m)} = ( 200 * 10 * 1000) / (2 * 3.14 * 4000)

T_{kV(N.m)} = 0.0796N.m.

2. The motor’s torque output is 0.0955N.m and is drawing 20 Amperes of current while spinning at 5000 RPM. Determine the kV rating of an electric motor.

Given: T_{kV(N.m)} = 0.0955N.m., I_{(A)} = 20A, RPM = 5000

The kV to torque, T_{kV(N.m)} = (kV_{(RPM/V)} * I_{(A)} * 1000) / ( 2 * pi * RPM)

kV_{(RPM/V)} = (T_{kV(N.m)} * 2 * pi * RPM) / I_{(A)} * 1000

kV_{(RPM/V)} =( 0.0955 * 2 * 3.14 * 5000) / (20 * 1000)

kV_{(RPM/V)} = 150RPM/V.
