Three-Phase Induction Motor: Rotating Field & Slip

Almost every motor spinning in modern industry — pumps, fans, conveyors, compressors — is a three-phase induction motor, and none of its parts ever touch: no brushes, no commutator, no permanent magnets. This simulator renders the stator's traveling magnetic field as it sweeps around the machine at the synchronous speed set by supply frequency and pole count, and shows the rotor's squirrel cage being dragged along just behind it by induction. Adjust frequency, pole pairs, supply voltage and load torque and the simulator solves the real equivalent-circuit torque-slip equation for the stable operating point, easing the rotor toward it the way rotor inertia would, while live readouts track synchronous speed, rotor speed, slip, developed torque, breakdown torque and rotor-current frequency — and if you push the load past the breakdown torque, the motor visibly stalls.
