Models of synchronous induction machines

Information

This package contains models of synchronous induction machines, based on space phasor theory:

SM_PermanentMagnet: synchronous induction machine with permanent magnet excitation, with damper cage
SM_ElectricalExcited: synchronous induction machine with electrical excitation and damper cage
SM_ReluctanceRotor: induction machine with reluctance rotor and damper cage
i.e. a squirrel cage rotor with magnetic poles due to different airgap width

These models use package SpacePhasors.
Please keep in mind:

We keep the same reference system as for motors, i.e.:
Positive RotorDisplacementAngle means acting as motor,
with positive electric power consumption and positive mechanical power output.
ElectricalAngle = p * MechanicalAngle
real axis = d-axis
imaginary= q-axis
Voltage induced by the magnet wheel (d-axis) is located in the q-axis.

Information

Model of a three phase permanent magnet synchronous induction machine.
Resistance and stray inductance of stator is modeled directly in stator phases, then using space phasor transformation and a rotor-fixed AirGap model. Resistance and stray inductance of rotor's squirrel cage is modeled in two axis of the rotor-fixed ccordinate system. Permanent magnet excitation is modelled by a constant equivalent excitation current feeding the d-axis. Only losses in stator and damper resistance are taken into account.
Whether a damper cage is present or not, can be selected with Boolean parameter useDamperCage (default = true).
Default values for machine's parameters (a realistic example) are:

number of pole pairs p	2
stator's moment of inertia	0.29	kg.m2
rotor's moment of inertia	0.29	kg.m2
nominal frequency fNominal	50	Hz
nominal voltage per phase	100	V RMS
no-load voltage per phase	112.3	V RMS @ nominal speed
nominal current per phase	100	A RMS
nominal torque	181.4	Nm
nominal speed	1500	rpm
nominal mechanical output	28.5	kW
nominal rotor angle	20.75	degree
efficiency	95.0	%
power factor	0.98
stator resistance	0.03	Ohm per phase in warm condition
stator reactance Xd	0.4	Ohm per phase in d-axis
stator reactance Xq	0.4	Ohm per phase in q-axis
stator stray reactance Xss	0.1	Ohm per phase
damper resistance in d-axis	0.04	Ohm in warm condition
damper resistance in q-axis	same as d-axis
damper stray reactance in d-axis XDds	0.05	Ohm
damper stray reactance in q-axis XDqs	same as d-axis
These values give the following inductances:
main field inductance in d-axis	(Xd - Xss)/(2pifNominal)
main field inductance in q-axis	(Xq - Xss)/(2pifNominal)
stator stray inductance per phase	Xss/(2pifNominal)
damper stray inductance in d-axis	XDds/(2pifNominal)
damper stray inductance in q-axis	XDqs/(2pifNominal)
