| Abstract |
The paper presents a model for simulating the behaviour of a squirrel-cage induction motor. The purpose of the simulation is to calculate the instantaneous torque and currents of the motor. This is done by defining ten geometrically identical phases in the rotor. From this equivalent model, a 13 by 13 inductance matrix (ten rotor phases and three stator phases) is generated using a commercial CAD-finite element program. This calculation is repeated for various rotor positions in order to include the effects of rotor and stator slotting and local saturation. The lnstantaneous currents and torque are then calculated with various forms of input voltage. The motor is considered to be at constant rated speed. |
