The NeveRest 3.7 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 6 mm D and the gearbox housing is 37 mm 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):
FIRST Legality:
Usage:
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 3.7:1 reduction, then the NeverRest 3.7 output shaft provides 25.9 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:
