Stator Winding Data for Line-Start PM Synchronous Motors

To access the stator winding data, double-click the Machine-Stator-Winding entry in the project tree.

The Stator Winding Data Properties window contains the following fields:

Winding tab

Winding Layers

The number of winding layers.

 

Winding Type

The type of stator winding. Click the button to open the Winding Type window and choose from Whole Coiled, Half Coiled, and Editor.

 

Parallel Branches

The number of parallel branches in the stator winding.

 

Conductors per Slot

The number of conductors per stator slot (0 for auto-design).

 

Coil Pitch

The coil pitch measured in number of slots.

 

Number of Strands

The number of wires per conductor (0 for auto-design).

 

Wire Wrap

The thickness of the double-sided wire wrap (0 to automatically obtain this value from the wire library).

 

Wire Size

The diameter of the wire (0 for auto-design). Click the button to open the Wire Size window where you can specify units, wire type, diameter, and gauge.

End/Insulation tab

Input Half-turn Length

Select or clear this check box to specify whether or not you want to enter the half-turn length. When this check box is selected, the Half Turn Length field appears the next time you open the Properties window. When this check box is selected, the End Adjustment field appears instead.

 

Half Turn Length

The half-turn length of the armature winding.

 

End Adjustment

The end length adjustment of the stator coils, which is the distance one end of the conductor extends vertically beyond the end of the stator.

 

Base Inner Radius

The inner radius of the base corner.

 

Tip Inner Diameter

The inner diameter of the coil tip.

 

End Clearance

The end clearance between two adjacent coils.

 

Slot Liner

The thickness of the slot liner insulation.

 

Wedge Thickness

The thickness of the wedge insulation.

 

Layer Insulation

The thickness of the insulation layer.

 

Limited Fill Factor

The limited slot fill factor for the wire design. The slot fill factor is the ratio between the cross-sectional area of all conductors in one slot and the entire slot area.
