A turntable is motorized for use in an electromagnetic compatibility chamber without degrading the performance of the chamber. Large turntable 10 (e.g., 16 feet diameter), is surrounded by a raised metal floor 11 with minimum clearance (e.g., seven inches) and is located in the chamber. Turntable 10 can go any number of degrees in either direction, or start and stop and restart again going in the same direction. The complete drive system is installed under the raised metal floor 11 without interfering with it. Positive displacement (vane type) air motor 15 is used for a prime mover and is directly attached to a speed-reducing (e.g., 60:1) gearbox. This assembly is bolted to a counterbalanced spring arm 16.
