MMF Source

R2026b

Ideal magnetomotive force source

• 

MMF Source block

To add a block to a model, double-click the canvas and start typing the block name. Then, select the block from the list.

Libraries:
Simscape / Foundation Library / Magnetic / Magnetic Sources

Description

The MMF Source block represents an ideal magnetomotive force (mmf) source that is powerful enough to maintain specified constant mmf across its output terminals, regardless of the flux flowing through the source.

You specify the output mmf by using the Constant mmf parameter. The mmf can be positive, negative, or zero.

Ports

Conserving

N — North terminal

magnetic

Magnetic conserving port associated with the north terminal.

Programmatic Use

Port: N

S — South terminal

magnetic

Magnetic conserving port associated with the south terminal.

Programmatic Use

Port: S

Parameters

Constant mmf — Output mmf

1 A (default) | scalar

Magnetomotive force output by the source.

Programmatic Use

Parameter: mmf0

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.

"fl_lib/Magnetic/Magnetic Sources/MMF Source"

Example: add_block("fl_lib/Magnetic/Magnetic Sources/MMF Source","myModel/myBlock",MakeNameUnique="on")

For information about programmatic access to individual block parameters, see the Programmatic Use section of parameter descriptions on this page.
