Do eddy currents in a rotor core of an induction motor create torque proportional to the coil current of a squirrel cage?
In a rotor of an induction motor, the core plates and wire coil conductors have non-zero thicknesses. Therefore, eddy currents non-zero too. And they approximately proportional to the coil current of ...

Torque developed by Star Connected rotor
The current in each phase of a Y-connected rotor winding is 200 amperes. The resistance per leg is 0.003 ohm. Determine the torque developed by the rotor at a slip of 3%.

Why don't I get a bell curve in the torque vs rotor position plot?
I have designed a inset PMSM. I tried to plot the torque vs. rotor position plot but I am not getting a bell curve. Like at the torque must be maximum only when theta is 90 degrees.
I don't know where ...

Induction motor starting torque and pull out torque
Recently I was doing some work on the induction motor where I found some general theory on starting speed torque curve of the induction motor. Where the theory is the starting torque will be 1.5x of ...
