Starlight Posi Drive Motor System for 2-Inch and 3-Inch Feather Touch Focusers
A model of the Starlight Posi Drive Motor System meant to be used with 2.7" Astro Physics, as well as 2.5" or 3.0" Feather Touch Focusers. The Posi Drive Motor System has a lift capacity in excess of 56 pounds, attaching to the pinion shaft rather than the assembly- eliminating the danger of slip and ensuring precise repeatability with heavier payloads. Meanwhile, the PDMS has 2.3 microns per step (.00009") which is 11,400 steps per inch. The PDMS-FT motor comes standard with an over-ride to allow for manually focusing with the Coarse focus knob. What is more, the PDMS motor has the thermistor built onto the motor circuit board for temperature compensation.
