RTE-Drive Machines

Block

Note: This block is obsolete.

This block implements a permanent magnet synchronous machine model using a phase domain representation model.

RTE-Drive Phase Domain PMSM Mask

Voltage base [V]	The model base voltage.
Current base [A]	The model base current.
Electric frequency base [Hz]	The model base frequency. Note that the base choice will not affect this model but are used to correlate to a similar model.
Number of Pair of Poles	The machine number of pole pair.
Open phase resistance [ohms]	The stator winding resistance when it is forced open using the OpenStator input signal. This resistance cannot be set arbitrarily to high value because of numerical stability concerns. Smaller time step allows higher open phase resistance.
Sample Time [s]	The model sample time.

Vabc [V]	The machine terminal voltages.
Bemf [V]	Internal BackEMF of the machine. Minimum torque generation occurs when the Back-EMF is in phase with terminal voltage. With regards to the rotor position, the Back-EMF is 90 degree (electric)in advance of the direct axis of the rotor.
Lx [pu]	The inverse of the reduced inductance matrix [2x2], which is time-varying.
Rstator [ohms]	The stator resistance [3x1].
OpenStator	The logic signal which controls the resistance of the stator. When equal to 1, the stator resistance is set equal to the <Open phase resistance> parameter. When equal to 0, the stator resistance is set equal to the Rstator input signal.

Iabc [A]	The machine currents.
Vneutral [V]	The machine neutral voltage.

Direct Feedthrough	No
Sample Time	Inherited and fixed discrete.
Work Offline	Yes
Dimensionalized	No

None.
