Abstract
A platen rotation apparatus includes a rotator assembly coupled with a platen. The rotator assembly operates in a first mode to increase a rotational kinetic energy of the platen based on an electrical energy input, and, in a second mode, to decrease the rotational kinetic energy of the platen and generate an electrical energy output based on the decreased rotational kinetic energy of the platen. An energy storage device electrically coupled with the rotator assembly provides the electrical energy input when the rotator assembly is in the first mode and receives the electrical energy output when the rotator assembly is in the second mode.
