#	Name	Type	Default	Units	Description
1	Phases	integer	3		Number of Phases, this Induction Machine.
2	Bus1	string (bus def.)			Bus to which the Induction Machine is connected. May include specific node specification.
3	kV	real	12.47	kV	Nominal rated (1.0 per unit) voltage, kV. For 2- and 3-phase machines, specify phase-phase kV. Otherwise, specify actual kV across each branch of the machine. If wye (star), specify phase-neutral kV. If delta or phase-phase connected, specify phase-phase kV.
4	kW	real	1000.0		Shaft Power, kW, for the Induction Machine. A positive value denotes power for a load. Negative value denotes an induction generator.
5	PF	real			[Read Only] Present power factor for the machine.
6	Conn	string (from enum. Connection)	Delta		Connection of stator: Delta or Wye. Default is Delta.
7	kVA	real	1200.0		Rated kVA for the machine.
8	H	real	1.0		Per unit mass constant of the machine. MW-sec/MVA.
9	D	real	1.0		Damping constant. Usual range is 0 to 4. Adjust to get damping in Dynamics mode,
10	puRs	real	0.005		Per unit stator resistance.
11	puXs	real	0.106		Per unit stator leakage reactance.
12	puRr	real	0.007		Per unit rotor resistance.
13	puXr	real	0.12		Per unit rotor leakage reactance.
14	puXm	real	4.0		Per unit magnetizing reactance.
15	Slip	real	0.007		Initial slip value.
16	MaxSlip	real	0.1		Max slip value to allow. Set this before setting slip.
17	SlipOption	string (from enum. Slip Option)	VariableSlip		Option for slip model.
18	Yearly	string (LoadShape name)			LOADSHAPE object to use for yearly simulations. Must be previously defined as a Loadshape object. Is set to the Daily load shape when Daily is defined. The daily load shape is repeated in this case. Set Status=Fixed to ignore Loadshape designation. Set to NONE to reset to no loadshape. The default is no variation.
19	Daily	string (LoadShape name)			LOADSHAPE object to use for daily simulations. Must be previously defined as a Loadshape object of 24 hrs, typically. Set Status=Fixed to ignore Loadshape designation. Set to NONE to reset to no loadshape. Default is no variation (constant) if not defined. Side effect: Sets Yearly load shape if not already defined.
20	Duty	string (LoadShape name)			LOADSHAPE object to use for duty cycle simulations. Must be previously defined as a Loadshape object. Typically would have time intervals less than 1 hr. Designate the number of points to solve using the Set Number=xxxx command. If there are fewer points in the actual shape, the shape is assumed to repeat.Set to NONE to reset to no loadshape. Set Status=Fixed to ignore Loadshape designation. Defaults to Daily curve If not specified.
21	DebugTrace	boolean	False		Write DebugTrace file.
22	Spectrum	string (Spectrum name)	default		Name of harmonic voltage or current spectrum for this IndMach012. Voltage behind Xd” for machine - default.
23	BaseFreq	real		Hz	Base Frequency for ratings.
24	Enabled	boolean	True		Indicates whether this element is enabled.
25	Like	string (IndMach012 name) deprecated			Make like another object, e.g.: New Capacitor.C2 like=c1 …
