NeveRest Orbital Gearmotor (Gear Ratio: 50.9 to 1) with JST-VH-2 Connector

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 a 6 mm D and the gearbox housing is 37 mm diameter.

FIRST Legality:

• 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.

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 40:1 reduction, then the NeverRest 40 output shaft provides 280 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.

This is the cable designed for the encoder that is pre-attached to the NeveRest Series of motors and gearmotors. It has a connector on the opposite end to directly interface with the REV Expansion Hub or the REV Control Hub.

2019 Update:

The 'a' version of this cable as the encoder channels swapped so that the encoder counts in the same direction as the output shaft spins. This simplifies the usage of the encoder with the various programming languages for FTC!

Specifications

• Length: 20 in.

Used to change motor to axle motion 90 degrees. This can be used in between the U-channel.

485 Servo Pack  is one of the best choices for rugged robotic applications. This servo’s great performance and durability are a combination of karbonite gears, high-performance circuitry, and a ball bearing-supported output shaft. Karbonite gearing is nearly four times stronger than nylon gears and provides virtually wear-free performance. Standard rotational range is 90 degrees, but it can be operated to 180 degrees with controllers capable of generating a pulse range from 600 usec to 2400 usec. Produces nearly 84 oz-in of torque power.

This power switch is legal for use in FTC competition.

This switch makes for a simple and satisfying power switch for a robot. It features easy to use XT30 connectors.

We've specially designed the mounting bracket to be compatible with most building systems..
