Abstract: 2103912 9312860 PCTABS00024 A drive system (184) that coordinates the rotation of a first and second rotating element, the first element (50) carrying the second element (52). The drive system also having a first motor (66) and a second motor (72), both motors having at least two poles (PA, PB). A drive control mechanism (186) is electrically connected to the poles of the first motor and the second motor. As the drive control rotates the first motor at a fixed rate, the first and second motors exchange power whenever a phase error occurs between the first and second motors. This power exchange eliminates the phase error and keeps the second motor in synch with and operating at the same rate as the first motor.
