Quick Overview

The DM-2 Digital Motor combines high power output ruggedness and high precision, in a small, compact size. Its right angle drive configuration allows for a simple lens interface. The worm gear set is lapped for very quiet low backlash operation. Electronic feedback is provided by an optical encoder for maximum reliability. The output gear is .8 cinema standard. Step up gears for meshing with Panavision or video lenses are also available.

Details

The DM2 motor is a smaller and lighter version of the original DM1. It is intended to perform the Focus, Iris or Zoom functions on all but the stiffest cinema lenses. (These jobs should still be relegated to its bigger brother DM1.) The length of the DM2 housing is 100mm (3.9"), compared to 120mm (4.7") for the DM1, while its weight has been reduced by 30% of the DM1; from 415g to 290g. It has the same rugged worm reduction gearing as the DM-1 with DLC coatings. It also shares motor housings which are machined from a solid bar of Magnesium alloy and coated with a special ceramic before painting. This combination provides exceptional resistance to salt spray and moisture. The small size and high resolution of the DM2 motor make it ideally suited for Steadicam and HDTV applications. Step-up gears are available for use with Panavision cinema lenses as well as Canon and Fujinon video lenses. The mounting brackets are the same for both the DM-1 and DM-2, and are available for use with 15mm, 19mm, and .625" rod systems. The DM-2 motor may be used interchangeably as a zoom focus or iris drive. A 15mm mounting rod is fixed to the motor body.Motor ships with 15mm rod and .80m output gear.
