Slot conductor

QuickField simulation example

This is an example of the slot of an electric machine simulation, performed with QuickField software.

Problem Type
Plane-parallel problem of heat transfer.

Geometry
Slot conductor Determine the temperature of the slot. Insulation Wedge Steel Cooling duct Conductor Conductor 40 mm 16 mm 100 mm 28 mm

Given
Copper conductor current density j=4.5 A/mm².
Copper electric conductivity g = 56 MS/m.

Task
Determine the temperature of the slot.

Solution
Due to electrical machine symmetry we simulate only one slot. QuickField heat transfer problem takes input power as a volume power density, which could be calculated as:
Q = j² / g = 360 kW/m³.

Result
Temperature distribution in slot conductor:
