Description

Stator main inductance

The stator main inductanceof anphase induction machine is related with the self inductance of on stator phase,,by:

Parameters of equivalent polyphase induction machines models

Assume a set parameters,,,,,of a three-phase induction machine and a set of parameters,,,,,of anphase induction machine. It is also assumed that

• the nominal phase voltages
• the nominal stator frequencies

of the three andphase induction machine are equal. In this case the two parameter sets are related by:

This way the same torque is generated and the machine currents are related by:

The same applies for the rotor parameters of aslip ring induction machine, where the phase numberis simply replaced byfor transforming equivalent three-phase tophase winding parameters -- at the same nominal rotor voltage and frequency.
