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 2018 FTC Game.
  • According to the FIRST Robotics Challenge Game Manual, Rule R33, this is legal for the 2018 FRC Game as it uses the NeveRest am-3104 motor.

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:
Theoretical Performance Specifications:
  • Gearbox Reduction: 19.2:1
  • Voltage: 12 Volt DC
  • No Load Free Speed, at gearbox output shaft: 340 RPM
  • Force Needed to Back-Drive: 6.4 oz-in
  • Gearbox Output Power: 14 W
  • Stall Torque: 175 oz-in
  • Stall Current: 11.5 A
  • Output counts per revolution of Output Shaft (cpr): 537.6
  • Output pulse per revolution of encoder shaft (ppr): 134.4

    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!
