That is known as a capacitor start - capacitor run motor. The
capacitor provides a phase shift between the two windings to
control the director the motor runs. Hy-Gain (CDE) rotators also
use capacitor start - capacitor run motors. Nothing "strange"
about them at all; the technique is rather common in fractional
horsepower reverseable motors.

It seems to be from the G-450 schematic that the rotor motor has two
winding one for one direction and other direction and the other for the
opposite direction and uses three wires to accomplish this feat. Very
strange design indeed.
