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.
FTC Legality:
According to the FIRST Tech Challenge Game Manual Part 1, Rule RE04 this is legal for the 2016-2017 FTC Game.
Encoder Cable options:
Encoder cables are not included with this motor, and are sold separately. We have two options:
- am-2992 is a 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 a cable which has the white 4-pin connector for the encoder on one end and 4 separate black connectors.
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.
