Stator main inductance
The stator main inductance
of an
phase induction machine is related with the self inductance of on stator phase,

Parameters of equivalent polyphase induction machines models
Assume a set parameters,

of a three-phase induction machine and a set of parameters,

of an
phase induction machine. It is also assumed that
- the nominal phase voltages
- the nominal stator frequencies
of the three and
phase 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 a
slip ring induction machine, where the phase number
is simply replaced by
for transforming equivalent three-phase to
phase winding parameters -- at the same nominal rotor voltage and frequency.
