RacetrackSlotCore UDP

The RacetrackSlotCore UDP is used to create a stator core with a single-phase concentric AC winding for single-phase induction machines. The stator may have up to three different slot sizes.

Property	Description
DiaGap	Core diameter on gap side, DiaGap < DiaYoke for outer cores.
DiaYoke	Core diameter on yoke side, DiaYoke < DiaGap for inner cores.
Length	Core length.
Skew	Skew angle in core length range.
Slots	Number of slots.
SlotType	Slot Type: 1 to 6.
Hs0	Slot opening height.
Hs01	Slot closed bridge height.
Hs1	Wedge height.
Hs2	Slot body height.
Bs0	Slot opening width.
Bs1	Slot wedge maximum width.
Bs2	Slot body bottom width, 0 for parallel teeth.
Rs	Slot body bottom fillet.
FilletType	0: a quarter circle; 1: a tangent connection; 2&3: arc bottom.
Poles	Number of poles.
WidYoke	Racetrack width for 2/4-pole cores.
MidSlots	Number of middle-size slots for 2/4-pole cores.
MidHs2	Middle-size slot body height for 2/4-pole cores.
MidBs2	Middle-size slot body bottom width for 2/4-pole cores.
SmlSlots	Number of small-size slots for 2/4-pole cores.
SmlHs2	Small-size slot body height for 2/4 pole cores.
SmlBs2	Small-size slot body bottom width for 2/4-pole cores.
SegAngle	Deviation angle for slot arches (10~30, <10 for true surface).
LenRegion	Region length.
InfoCore	0: Core; 100: region.

These parameters are demonstrated in the following Racetrack SlotCore example. The first figure shows the parameters on cross-section of RacetrackSlotCore:

The next figure shows the parameters on axial direction of RacetrackSlotCore:

Note: For parameters such as Skew, FilletType, SegAngle and parameters related to slots, refer to SlotCore UDP parameters.
