WarpAstron WarpDrive WD-17S Harmonic Drive Mount

WD-17S is the first harmonic drive mount based on Servo Direct Drive technology. It has only single stage reducer – backlash less strain wave reducer, and eliminate the transmission/assembly error from belt/planetary gear solution. That’s why we called “harmonic drive” mount, providing high precision guiding performance to you.

RA axis using Type 17 SWR which providing same load capacity like most of harmonic drive mounts at the same time. It only weighted 3.8kg including support both Vixen & Losmandy dovetails.

Optimize base can be smoothly fine adjusted with CNC fine tooth screw and gap control design, which make it much easier for polar alignment.

Servo Direct Drive

Servo motor direct driving stain wave reducer, taking advantage of fast response and precise positioning, every mount provides constantly high precision guiding at the same level.

Easy partner

Only weighted 5.4kg supporting both Losmandy & Vixen dovetail, thickness of mainbody up to 1cm.

Low Temperature Friendly

Operating environment lower to -25℃, Powerful direct drive & Special heating design.

High precision encoder

Ensure high precision positioning for servo motor, far exceeding any stepper.

GPS

GPS/Beidou positioning module inside, for automatic positioning which easily sync time/location to NINA etc. for outdoor operation.

Maintenance Free

Constantly powerful driving by servo motor. No belt tension adjustment issues due to aging.
