It's a hybrid of the VMW belt/splutch and the Oasis/Fisher&Paykel SmartDrive. It's a BPM rotor/stator drive, but mounted onto the gearbox of the VMW. This is why the tub rotates against the wash plate, rather than just floating back and forth like the Oasis, but I suppose it also alleviates the issues that could arise with the floating wash basket system, and provides gear reduction to reduce stress directly against the rotor and stator. It uses a solenoid to lock the tub and wash plate together for rotation and spin.
