Dual oil pump with centrifugal shifter

A dynamo-electric machine comprising:

• a dual oil pump comprising:
• a housing assembly, the housing assembly defining an inlet and an outlet;
• a carrier assembly, the carrier assembly being rotatably connected to the housing assembly;
• a pump shaft, the pump shaft being non-rotatably connected to and configured to axially translate relative to the carrier assembly;
• a first mechanical pump, the pump shaft being non-rotatably connected to and configured to axially translate relative to the first mechanical pump;
• a second mechanical pump, the first mechanical pump and the second mechanical pump being radially aligned and axially offset from each other, the first mechanical pump and the second mechanical pump being disposed axially within and radially within the housing assembly, the first mechanical pump and the second mechanical pump being configured to pump oil from the inlet to the outlet via rotation of respective of the first mechanical pump and the second mechanical pump relative to the housing assembly;
• and
• a dog clutch, the dog clutch being formed by the pump shaft and the second mechanical pump, the dog clutch being a non-rotatable connection between the pump shaft and the second mechanical pump when closed and permitting relative rotation between the pump shaft and the second mechanical pump when open, the dog clutch being closed and opened by axial translation of the pump shaft relative to the second mechanical pump, the pump shaft being configured to axially translate relative to the housing assembly, the carrier assembly, the first mechanical pump, and the second mechanical pump via centrifugal shifting caused by rotation of the carrier assembly and the pump shaft about a center axis;
• a rotor;
• a stator, the rotor and the stator forming an outer-rotor, inner-stator radial flux machine;
• an input shaft;
• and
• a rotor carrier, the rotor, the input shaft, the rotor carrier, and the carrier assembly forming a rigid body.
