Properties

This model is general enough to represent most industrial three-phase induction motors with 1 or 2 squirrel cage rotors or with wound rotors.

Main Features

The model is equipped with connectors to the control module in order to facilitate modeling of the mechanical load.

Induction Motor Model

The induction motor model can be represented by four pairs of equations.
The electrical equations convert the voltage signals into electrical fluxes in a DQ Park representation.
A saturation relation introduces the non-linearity of mutual inductance in the motor. The current equations convert the fluxes for both rotor and stator into currents on the DQ axes. Finally,
the mechanical equations represent the rotor speed, using mechanical and electrical torques and taking into account inertia and friction.
