No gears NO belts. Precise closed loop control.
In professional astronomy direct drive technology has been used for some years now. We developed our own direct drive controller and motor system. No gears or belts are needed, there is no transmission no periodic error or backlash.
On the picture on the right you can see a completely, in-house CAD- and CNC-manufactured rotor of a direct drive motor for a telescope.
Direct drive means
- Fast acceleration – necessary for satellite tracking
- very stable and stiff
- precise pointing and tracking
- longer life expectancies because there is no wear & tear (since no moving parts)
- low to no-sound operation
- low power consumption
