Torque calculation in induction disk type relay

Torque calculation in induction disk type relay

Torque calculation in induction disk type relay

Can anyone point me to any references which gives the calculation for torque generated in an induction disk type relay? I am aware of "very basic" expressions for the torque as in this link (https://www.eeeguide.com/induction-relay-torque-eq...), but I was wonder if there exists any reference which I can use to calculate the torque numbers (not just a basic expression).

RE: Torque calculation in induction disk type relay

What else do you need? For an α of 90 (or 270) degrees, torque is a maximum, so sin(α) becomes a 1 and drops out of the equation. Two currents and a frequency multiplied together is a pretty easy solution to arrive at.

To MacGyver2000...
(1) How to calculate the induced current?
(2) What is the proportionality constant?
