Product Overview:
The NeveRest 40 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 diameter.

This is the same as part 'am-2964' as per the manual, these have the addition of power pole connectors pre-attached!

FTC Legal:
According to the FIRST Tech Challenge Game Manual Part 1, Rule RE09 this is legal for the 2016-2017 FTC Game.

Encoder cables are not included with this motor.  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 40:1 reduction, then the NeverRest 40 output shaft provides 280 ppr.
