Squirrel cage rotor^*

AC motors often feature the squirrel cage rotor. The squirrel cage is a special type of rotor winding. The current flows in every branch of the winding. The ends of branches on each side of the squirrel cage rotor are short circuited. The total current of all branches at any moment of time is zero.

To model the squirrel-cage rotor the AC Magnetics module is suitable. The same labels should be assigned to the winding blocks. Then in the block label properties dialog the zero total current source should be specified. Also the flag 'all conductors connected in parallel' should be checked.
