Summary:The subject of the article is a computer model of a multi-phase squirrel cage induction motor with a stator number phases greater than 3. This model is written in the Matlab / Simulink language and is presented graphically in the form of a multi-terminal block. A system of differential equations describing a multiphase motor was introduced by the use of Simulink library blocks. This system of equations takes into account the interaction of higher spatial harmonics. The block of equations is connected to the external power circuit by means of the so-called ideal transformers. This allows for modeling not only the electric drive, but also the internal waveforms of the converter and the power supply system. Application of the model was illustrated by the operation of a nine-phase motor powered by a frequency-controlled voltage source inverter at a variable supply sequence and referred to measurements.
