The old Brusa AMC motor controllers (circa 1993), have a Delta / Wye input...
Delta is about twice the RPM, and about half the torque of Wye.
Wye is about twice the torque, and about half the RPM of Delta.
An external contactor is used to switch the ACgtx20 motor between the two wiring configurations (all coils are in the junction box):
Delta:

Wye:

Note: you would bring all the coils out to your Delta/Wye contactor.
The Delta / Wye input tells the AMC motor controller which parameter set to use (resistance, inductance, back EMF, etc... changes between the two modes).
My test box even supports this feature:

My truck in Delta has a max speed of 70MPH.
My truck in Wye has a max speed of 35MPH (but acceleration is twice that of Delta).
