The 120V TwinSpin Variable Speed Dual Pattern Rotator from GAM PRODUCTS uses silent drive belts to rotate 2 patterns in opposite directions. It is designed for use in ellipsoidal spotlights for projected effects, using 'B' size patterns.
A low voltage motor is mounted on vibration pads, which minimize noise transmission to 20 gauge stainless steel plates. The motor is offset away from the hot air flow and drives 2 special hi-temp belts to quietly rotate 2 gobo rings in opposite directions. The gobo rings have a groove to receive drive belts around the edges, and a machined recessed groove to hold the gobo pattern and spring steel retaining the ring in place. Teflon glides are placed between the gobo rings and an outer housing to ensure a quiet and smooth operation.
The variable speed motor can be controlled by almost any dimmer, and does not need any special cables or controller. The motor is powered by a UL approved power transformer. The unit may be programmed from a standard light board and controlled as a part of a light cue.
