"Product Overview:
The NeveRest is a gearbox and motor combination with an attached encoder designed with FIRST Tech Challenge teams in mind, by including geometry that matches existing bolt patterns. The shaft is 6mm in diameter and the gearbox housing is 37mm in diameter. The power cable which feeds into the black encoder housing for the motor has two powerpole connectors already crimped to the end of the cable making the gearmotor or motor by itself, ready to use.

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 comes 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.

Met our needs to power a ball launcher for FTC February 6, 2017
Reviewer: Andrew Lieberman from South San Francisco, CA United States  
The motors that came in our basic FTC robotics kit were not fast enough to power a ball launcher, so after doing some research, we tried these, and they did the trick with plenty of speed to spare.

They are a little bigger than the other motors we had, so the mounts we already had didn't fit them perfectly, but they worked ok. For next season, I will buy the correct mounts.

Don't forget to buy your Hall Effect Encoder Cable with 4-pin Connector (am-2992) to go with each motor.
