PlaneWave’s A200 German Equatorial Mount comes standard with high-resolution Axis Encoders on both Right Ascension and Declination axes.
The A200 encoder technology is a breakthrough in value for a telescope mount using quality components usually founds in professional equipment costingthousands more.
The A200 uses a non-contact encoder design that offers high speed, reliable operation with zero friction and zero wear.
The encoders sits above a 20 µm thin flexible steel strip, which is gold plated to give high reflectivity and corrosion resistance. This ensured repeatable, precise results for the life of your mount.
For added precision and accuracy the CDK700 not only uses high resolution encoders, but also employs a Direct Drive motor system. Direct Drive motors means that there are no gears to cause backlash or periodic error while slewing and tracking. With the high resolution encoders providing the feedback for the direct drive motors, not only will the telescope track without periodic error or have any backlash at all, but the mount will be able to counter against wind gusts. The direct drive motors can move the telescope at incredible speeds for tracking satellites or just to minimize target acquisition time.
The Direct Drive system is composed of 24 coils and 32 neodymium magnets powered by a 3-Phase Axial-Flux Torque Motor.
Combined with a hi-res encoder and stainless steel encoder tape on the circumference, the drive yields 16 million counts per revolution, or about 0.08 arcsecond resolution.
