Losmandy-Maxom motors

 

The Part number for the Maxom motor and Encoder is SVMM  with cost of $300.00 each (Discontinued)

The Part number of the standard motor and encoder is SVM with cost of $200.00 each Discontinued)

Losmandy has come out with a new High Torque motor SVM-HT with cost of $225.00
It is the only motor they now offer to work with the Gemini-1 and Gemini-2
It is suppose to me 70mm long where the old standard motor was 58mm long.
It also is suppose to have even high torque than the Maxom motors.

Here is a link to the pictures of the new motor on the  Losmandy site.

Please see the Losmandy Price list for current pricing.
