New version of this mount is ready for production. In the new version there is no reducers. Servo motors are directly connected to the axes. All electronic equipments are OMRON and there is a small PC that drives all features of the mount such as guiding, programmable astrophotography and many other. It will be on the market about late summer I guess. Another key feature is the weight of the mount; less than 30kg / 66lbs (without counterweights and counterweight shaft).
That would work. Nice to see someone using Brushless servos though. What is the PLC's function? Are you developing your own goto system in Ladder Logic?
PLC is for main control and the interface with the computer software and Servos. I'm developing a software which runs in a small industrial PC for goto and guiding system. Mount will have a touch screen that provides full control of the system.

Not entirely backlash free as it does contain gears.
The stepper motor is attached to a VRSF-250-400 planetary gear servo reducer, helical in design. Typically 15, 5 or 3 arc minutes.
Available gear ratios for the VRSF models are 3, 5, 9, 15, 25, 45 and 81. 6,000 RPM input maximum.
Basically, this is the transmission section between the worm gear and stepper. You can't really drive a scope directly off a stepper because it would be choppy.

Are you producing this mount yet? Do you have any US distributors? I would be interested.

only the color is nearly same. I have 5 different colors.

Nicw work ! a little bit loud, as for me :)

Nice work there. You could probably use smaller Servo's than 400W especially with the amount of reduction you have there.

They will be replaced with 100W ones in the final product.

Mount is so strong that you even don't need counter weights for telescopes up to 30kgs.

Where your weight?Bye!

I like the belt system. No backlash, great.
