The Posi Drive Motor System for the Feather Touch focuser can lift in excess of 56 pounds. This motor system attaches to the pinion shaft and not the reduction assembly which eliminates any slip and offers precise repeatability with heavier payloads. 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. The PDMS motor has the thermistor built onto the motor circuit board for temperature compensation.
