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):
- NEW for 2020! JST-VH-2 connectors Option: this option plugs directly into the FIRST Tech Challenge REV Controller
- Anderson Powerpole 15A connectors Option
- According to the FIRST Tech Challenge Game Manual Part 1, Rule RE10, this is legal for the 2020-2021 FTC Game.
- According to the FIRST Robotics Challenge Game Manual, Rule R27, this is legal for the 2020-2021 FRC Game as it uses the NeveRest am-3104 motor.
- PicoBox LEO (am-3614). This gearbox is used for creating chain drives for mechanisms like arms.
- PicoBox GEO (am-3616). This gearbox combines two orbital NeveRest motors into a single output shaft allowing for combined power at a low ratio.
- PicoBox MEO (am-3615). This gearbox accepts one NeveRest motor and allows for gear changing through PicoBox gearing.
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.

"Met our needs to power a ball launcher for FTC"
"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."
