SI-PDMS–Posi Drive Motor System
$590.00 – $670.00
Description
The Posi Drive Motor System for the Feather Touch focuser can lift in excess of 56 pounds. This motor system has two attachment options:
Standard: The motor attaches to the pinion shaft and not the reduction assembly which eliminates any slip and offers precise repeatability with heavier payloads. The standard configuration PDMS has 2.2 microns per step (0.000087″) which is 11,494 steps per inch.
High Resolution: The motor attaches to the reduction assembly, offering much finer step resolution for precise focusing. The high resolution configuration PDMS has 0.25 microns per step (0.0000095″) which is 105,263 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.
