Product Overview:
The NeveRest 60 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 6mm dia and the gearbox housing is 37mm 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 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.
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 60:1 reduction, then the NeverRest 60 output shaft provides 420 ppr.

Working with the Encoders:

Reviewer: Charles Rightmyer from San Diego, CA United States  
I have found that your products are generally quite satisfactory.  I have found, however, that some of the sensors, the color sensor for instance, does not work as expected with the ftc example code.  With help from your support staff, I have been able to sort that out, but with the huge number of ftc users, in my opinion, it would be worth the effort to sort that out before next season.
