STEP 0: Pre-Calculation Summary
Formula Used
Driving Torque = K (spring)*Speed
Td = K*N
This formula uses 3 Variables
Variables Used
Driving Torque - (Measured in Newton Meter) - Driving Torque id the amount of torque produced by the electromagnets in an energy meter.
K (spring) - (Measured in Newton Meter per Radian) - K (spring) gives the spring constant of the spring.
Speed - (Measured in Radian per Second) - Speed is the speed with which the disc in the energy meter is rotating.
STEP 1: Convert Input(s) to Base Unit
K (spring): 1.2E-05 Newton Meter per Radian --> 1.2E-05 Newton Meter per Radian No Conversion Required
Speed: 100 Revolution per Second --> 628.318530685963 Radian per Second (Check conversion here)

How does driving torque work?

Electromagnet 1 is excited by a line current and flu is set up. Electromagnet 2 is connected across the supply and current is proportional to the supply. Flux produced by EM2 lags behind flux produced by EM1 by 90 degrees. Both fluxes induce EMF in disc producing circulatory eddy currents. The reaction between fluxes and eddy currents gives rise to driving torque.
