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!

FRC/FTC Legality:
  • According to the FIRST Tech Challenge Game Manual Part 1, Rule RE09, this is legal for the 2019-2020 FTC Game (SKYSTONE).
  • According to the FIRST Robotics Challenge Game Manual, Rule R34, this is legal for the 2019 FRC Game (Destination: Deep Space) as it uses the NeveRest am-3104 motor.

Encoder Cable Options:
The NeveRest Classic 40 does not currently come with our am-2992 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 an optional encoder cable which has the white 4-pin connector on one end and 4 separate black connectors on the other end.

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

Working with the Encoders:
Performance Specs:
Force Needed to Break Gearbox: 1478 oz-in
Time to Failure at Stall: 2 minutes, 54 seconds
Motor Case Temperature at Failure: 190 degrees F

More Information:
Cougar Robotics 4251 has done some great research on this motor. See their notes on our motor.

    All Things Considered - A Good Product

    We purchased the NeveRest am-2964a motors to replace our TETRIX motors. After about 2 weeks of testing/driving, one of the pinion gears broke free from the motor axle. As we had purchase 2 extra motors, we chose to replace both of the motors on the robot to allow for even wear and tear. Within 10 minutes, one of the new motors suffered the same failure. As we were less than 48 hours to a scrimmage meet, we elected to use J.B. Weld to secure the pinion gears to the axles to move forward. Up to this point, we have had no other pinion gear failures, so it is possible we just had 2 random/fluke failures. Beyond that, these motors are great! The encoders are predictable in their behavior and are securely affixed to the motors. All-in-all, a good product.

    Great motors, watch the attached gearboxes

    We used NeveRest motors in FTC's Cascade Effect game on both our drivetrain and lift. For the lift they were fantastic. We used them as servos, frequently making them hold position to hold the lift at a given height. Their ability to hold position in a stall condition for extended times was critical to our application. We used them for the same reason on the drivetrain. If we stalled during auto we were still going to have good motors for Teleop. The NeveRest motors could run all of Auto at stall and still be ready for teleop. The only thing to watch with them is the gearbox. The motor is so good that now the attached (built-in) gearbox is the weakest link in the chain. We have had gearboxes fail and not noticed it immediately. The other motors on our drivetrain would pick up the slack and the robot would drive OK but not great. It became critical to write some test programs to detect the gearbox failures in the drivetrain motors so that we could swap them out between matches.

    "Update on Motor Performance"

    "I am updating my last comments with more info gained with more experience. We have broken a second gearbox. Likely our robot is near the maximum torque allowed on the gear box and impacts to the drive train are damaging the gears. What is really needed with these motors is a flexible coupler to soak up impacts and not transmit the shock to the gear box. We achieved about 2-3 hours out of each gearbox. When replacing one of the motors we had an encoder fail on the new installed motor. It was delivering 2x the pulses specified. Swapping it out fixed the issue. Still we like these a lot better than the Tetrix motors and the gearbox failures are likely an issue with our current design.... living on the edge just like a race car engine! Last comment... we installed Anderson Power Poles near the motors on the DC power wires so the motors can be swapped out quickly."

    We Like These Motors

    These motors are nice for FTC in applications where you might experience prolonged stall. The encoder is built into the tail of the motor, so the body of the motor is longer than Tetrix motor, but that gives more usable shaft because the USDigital encoder is not mounted on the shaft. Turns the opposite direction as a Tetrix motor and has different number of encoder ticks/rev, but that can be managed.

    "Great Motor But Be Aware of some Issues"

    "Seemed really solid but they have some issues: Longer overall length due to encoder on back. Encoder plugs are not keyed and have issues inserting both into the Motor Controller box. They are really difficult to insert both... they are not to spec for the encoder box! Harder to change out in a hurry as you have to remove all the wiring from motor to the controller (important during competitions). Matrix has disconnects at the motor. Broke a tooth in the gearbox 2/3 through our second competition. Not burning up during a stall is great! Textrix has undersize power resistor that burns up in about 10 seconds during stall conditions."

But these are better than all the others both in quality and price."

    "Really cool, but what's with the mounting?"

    "It's really nice to see alternatives to the Tetrix DC motors in FTC and I love the price, robustness, and built-in encoder on these. The ability to mount them in standard Tetrix motor mounts is of course quite nice. But we're using the bolt circle for a face-mount configuration in our drivetrain, and I can't help but ask this: Why on earth are the mounting holes M3? Every other Tetrix component uses #6-32 screws. Everything is made for them, and teams have them in plenty. Teams who want to take advantage of the awesome face-mounting capability now need to not only buy and keep track of another size of screw (That is very similar to #6-32 and could easily cause mix-ups), they also need to buy and keep track of a 2.5mm allen key (Again, easy to mix up with a 7/64 allen key) to install them. Again, the motors are great, but I'd love to see future versions with #6-32 mounting holes."

The gearbox looks super solid and the 2 minute plus life at axle stall under power should be far superior to the Tetrix motor as well. The one complaint I have at this point is the encoder cable connection... granted they give us fair warning that cable is not included but from the pic I thought it might be compatible with the encoder cable for the pitsco encoder. IT IS NOT so buy the cables! The fact that it has integrated encoder at this price point FAR outweighs the negative! $30/35 for what should be a superior performing motor versus $110 for the Tetrix setup... How could I complain!
