Product Overview

The NeveRest Orbital 20 is a gearmotor with an attached encoder. The output shaft geometry and the gearbox housing diameter is similar to what FIRST Tech Challenge teams are familiar with, and it shares a mounting interface with the NeveRest Orbital 3.7. (This is a different mounting pattern than the NeveRest Classic 20, 40, and 60.) The shaft is 6mm diameter and the gearbox housing is 36 mm in diameter. The power cable which feeds into the black encoder housing has two Powerpole connectors already crimped to the end of the cable.

FRC/FTC Legality: 
  • According to the FIRST Tech Challenge Game Manual Part 1, Rule RE09, this is legal for the 2019-2020 FTC Game (SKYSTONE).
  • According to the FIRST Robotics Challenge Game Manual, Rule R34, this is legal for the 2020 FRC Game (INFINITE RECHARGE.) as it uses the NeveRest am-3104 motor.
Mounting Plate Options: Encoder Cable Options:
The NeveRest Orbital 20 does not currently come with our am-2992 cable which has the white 4-pin connector for the encoder and also the black 4-pin connector for the HiTechnic and Modern Robotics motor controller. am-2993 is an optional encoder cable which has the white 4-pin connector on one end and 4 separate black connectors on the other end.

Encoder:
There is an encoder mounted to the back side of this motor. It is a 7 pulse per revolution (ppr) hall effect encoder. Since the motor's gearbox has a 19.2:1 reduction, the NeverRest Orbital 20 output shaft provides 134.4 ppr, or 537.6 counts per revolution within the software environment.

Working with the Encoders:

    I was frustrated to find that the old motor mounts do not fit these motors. I also did not initially notice that the shaft is not off center which is a big difference from old motors also. Be careful when you order them that you are taking these things into consideration. From the AndyMark Support Team: We're sorry for any confusion about the specs of the NeveRest 20 Orbital compared to the NeveRest Classic 40. With any questions about out products or how to use them, feel free to call (765-868-4779, 9-5 Eastern Time) or email us (support@andymark.com) and we're happy to help.

    VERY happy with this motor

    We have had no trouble at all with using the orbital 20's on our drivetrain. Last year our robot chewed up the old 20's and we were a little leery about trying the new orbitals. Glad we did!

    Thus far excellent

    bought these to replace the spur gear 20:1 motors in our drive train after we fried one. Far more robust, thus far working well.

    First order

    My first order went very smoothly. I made 2 orders for the same motors within minutes for 2 different teams and I appreciated the contact from Mary Baker to verify I did not submit a duplicate order by mistake. Great service!
