How to calculate the torque from the motor rating

It is certain to calculate with the motor rotating-torque (N-T) characteristics.

 

N : Rotation speed r/min
T : Torque N• m
H : Rated output kW

 

So,

 

H=T×(2 πN/60)÷1000
T=(60000/2π)H÷N

 

(Example)
When the motor of 1800 r/min, 1kw

T=60000÷(2π)×1÷1800=5.3 N• m

 

Please select the torque meter based on the maximum torque value.
