Winding

Name	Parameter	Default
num_phases	number of phases (m)
num_wires	number of wires per slot
coil_span	coil span
num_layers	number of layers
resistance	elect. resistance (Ohm)
cufilfact	Fill factor of copper	0.45
culength	rel length of conductor	1.4
cuconduc	conductivity (S/m)	56e6
slot_indul	insulation thickness in slot	0.0
material	name of material

Note

The material parameter references a dict item in the list of Conductors material. It overrides the cuconduc value and is the preferred method.

End-Winding Leakage

Windings may contain a leakage dict: leak_dist_wind, leak_evol_wind, leak_tooth_wind (version added 0.9.9)

• leak_dist_wind

  Name	Parameter	Unit
  perimrad	Radius of perimeter	m
  vbendrad	Bending radius vertical	m
  endheight	End winding height	m
  m.wiredia	Wire diameter	m

• leak_evol_wind

  Name	Parameter	Unit
  evol1rad	Top radius of first evolvent	m
  evol2rad	Top radius of second evolvent	m
  botlevel	Level at bottom of evolvents	m
  toplevel	Level at top of evolvents	m
  evolbend	Bending radius	m
  endheight	End winding height	m
  m.wiredia	Wire diameter	m

• leak_tooth_wind

  Name	Parameter	Unit
  bendrad	Bending radius vertical	m
  endheight	End winding height	m
  m.wiredia	Wire diameter	m

  Example:

  winding=dict(
      num_phases=3,
      num_wires=100,
      coil_span=3.0,
      num_layers=1,
      leak_dist_wind=dict(
          perimrad=67.1e-3, # Radius of perimeter [m]
          vbendrad=5e-3,    # Bending radius vertical [m]
          endheight=20e-3,  # End winding height [m]
          wiredia=1e-3)     # Wire diameter [m]
  )
