Summary
PolyphaseCircuit Class for finite-element representation of polyphase circuits.
this = PolyphaseCircuit(name, winding_spec)
Returns a new PolyphaseCircuit object with the given name and associated with the PolyphaseWinding winding specification.
A PolyphaseCircuit is largely characterized by its winding_spec property = a PolyphaseWindingSpec object. This winding specification object contains information such as number of turns and parallel paths, winding layout matrix, loop matrix, etc.
The PolyphaseCircuit then handles the finite-element representation of the winding, as well as the different supply modes. See this.set_load. Documentation for PolyphaseCircuit doc PolyphaseCircuit
PROPERTIES
- PolyphaseCircuit.circuit_analysis_arguments is a property.
- include_lew - include end-winding inductance, boolean
- supply_mode - supply mode.
- winding_spec - winding parameters specification; a PolyphaseWinding object
