WARPDRIVE WD-20 mount from WarpAstron


Thursday, June 20, 2024

Richard Harris Richard Harris

The WD-20 high-load harmonic drive mount, utilizing Servo Direct Drive technology, offers a load capacity of 50NM without a counterweight. Ideal for heavy equipment like 130APO, 150APO, and C11, it ensures excellent guiding performance. The new design with a high power density servo motor keeps its weight at just 12lbs.

The harmonic drive race is full-steam-ahead, and the WD-20 mount is focused in on being a high-load harmonic drive mount, utilizing Servo Direct Drive technology. It offers a standard load capacity of up to 50NM (Newton meters, about 36 lbs) without needing a counterweight, making it capable of handling heavy equipment such as the 130APO, 150APO, or C11 with optimal guiding performance.

The newly designed main body incorporates a high power density servo motor, significantly enhancing load capacity while maintaining a weight of just 5.4 kg (9.7 lbs).

Both axes feature home sensors, simplifying remote control and observatory astrophotography.

High-precision servo motor direct drive

  • The Right Ascension (RA) and Declination (DEC) axes are driven by servo motors equipped with high-precision encoders. This configuration ensures high positioning accuracy, silent operation, and eliminates drawbacks such as vibration and stepping that can occur with traditional stepper motor-driven systems.
     
  • The motor shafts are rigidly connected to the harmonic input for direct drive, without the need for additional belts or planetary gear reduction mechanisms. This design eliminates issues associated with belt aging, tension variations, and backlash problems that can occur with planetary gear reducers, ensuring consistent precision.
