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 FTC teams are familiar with. The shaft is a 6mm D and the gearbox housing is 37mm diameter.

The power cable which feeds into the black encoder housing has two different options that are already crimped to the end of the cable. (select your needs above):
  1. NEW for 2020! JST VH 2-pin connectors Option: this option plugs directly into the FIRST Tech Challenge REV Controller
  2. Anderson Powerpole 15A connectors Option

FIRST Legality:

  • According to the FIRST Tech Challenge Game Manual Part 1, Rule RE10, this is legal for the 2020-2021 FTC Game. 
  • According to the FIRST Robotics Challenge Game Manual, Rule R27, this is legal for the 2020-2021 FRC Game as it uses the NeveRest am-3104 motor.

Usage:

  • PicoBox LEO (am-3614). This gearbox is used for creating chain drives for mechanisms like arms.
  • PicoBox GEO (am-3616). This gearbox combines two orbital NeveRest motors into a single output shaft allowing for combined power at a low ratio.
  • PicoBox MEO (am-3615). This gearbox accepts one NeveRest motor and allows for gear changing through PicoBox gearing.

Encoder:
There is an encoder mounted to the backside 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, then the NeverRest Orbital 20 output shaft provides 134.4 ppr.

Encoder Cable Options:
NeveRest motors do not come with an encoder cable as we offer 3 cable options: 

am-3926a allows you to connect the encoder directly to the FIRST Tech Challenge REV Controller. am-2992 has the 4 encoder pins joined in one housing using standard 0.1" spacing. am-2993 allows you to break out the 4 pins separately if you need them in a different order.

Working with the Encoders: Performance Specs:
Time to Failure at Stall: 2 minutes, 54 seconds
Motor Case Temperature at Failure: 190 degrees F

    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!
