The lifting force is perpendicular to the plane of rotation. If the helicopter is rising, there is a component of velocity parallel to the axis of the rotor. Then the relative wind is the result of the rotational velocity and the vertical velocity of the helicopter. Lift acts perpendicular to the relative wind.

Rotary converter Wikipedia

The rotary converter can be thought of as a motor-generator, where the two machines share a single rotating armature and set of field coils. The basic construction of the rotary converter consists of a DC generator (dynamo) with a set of slip rings tapped into its rotor windings at evenly spaced intervals. When a dynamo is spun the electric

Unbalance Unbalance in Couplings Update International inc.

As most primary rotors, such as armatures, fanwheels and pump impellers are dynamically balanced, one of the worst remaining sources for creating larger than necessary amplitudes at 1 x rpm, is coupling unbalance. Mediocre to poor coupling balance is probably the weakest link of the various coupled rotors.
