The REV NEO Brushless Motor (REV-21-1650) is the first brushless motor designed to meet the unique demands of the FRC community. Offering an incredible power to weight ratio along with it's compact size it's designed to be a drop-in replacement for CIM-style motors as well as an easy install with mounting options.
Drop-in replacement for CIM-style motors
Shielded out-runner construction
Front and rear ball bearings
High-temperature neodymium magnets
High-flex silicone motor wires
Integrated motor sensor
3-phase hall sensors
Motor temperature sensor
Empirical means based on observations or experience. Theoretical means based on theories and hypotheses. The two terms are often used in scientific practice to refer to data, methods, or probabilities. When we refer to empirical data, we refer to values that were produced via testing. When our documentation refers to theoretical values, those are values that are based on what the product can do, in theory, but have not directly been produced.

1 - 10-32 x 3/8in long Socket Head Screw
Press Fit Pinion
Arbor Press
Do not attempt to run the NEO while a screw is still attached to the back of the motor. Not removing the screw will damage the motor and/or shaft.
NEO V1.0 (REV-21-1650)
A high-quality 1.5mm Allen Key (i.e. WERA Tools, Bondhus)
Loctite 242
Arbor Press
1) Take a 10-32 x 3/8in long socket head screw and screw it into the back of the motor finger tight.
DO NOT USE AN ALLEN WRENCH The screw is intended to support the end of the NEO's shaft while pressing on the pinion. Tightening the support screw with an Allen wrench may damage the motor and/or shaft.
2) Using a flat arbor press plate, balance the motor with that screw down on the arbor press
3) Proceed with pressing the pinion as usual. When complete, ensure that you remove the 10-32 socket head screw from the back of the NEO.
1) Locate the first of three screws holding the back can to the front plate of the motor.
2) Using a high-quality 1.5mm Allen Key, remove the bolt and set aside. Repeat this for the other two bolts around the back can. Make sure the Allen Key is fully seated in the bolt head during removal.
3) Remove the back can. Set it and the three bolts aside for reassembly after pressing on the pinion.
4) Place the NEO upright in the arbor press. Make sure to hold the bottom of the motor flat against the press plate, supporting the bottom of the shaft.
5) Press on pinion. After pinion is pressed on reattach the back can. We recommend using Loctite 242 to complete the reassembly.
The REV NEO Brushless Motor V1.1 (REV-21-1650) is the initial update on the first brushless motor designed to meet the unique demands of the FIRST Robotics Competition community. NEO V1.1 offers an incredible power density due to its compact size and reduced weight, and it's designed to be a drop-in replacement for CIM-style motors, as well as an easy install with many mounting options. The built-in hall-effect encoder guarantees low-speed torque performance while enabling smart control without additional hardware. NEO V1.1 has been optimized to work with the SPARK MAX Motor Controller (REV-21-2158) to deliver incredible performance and feedback.
Drop-in replacement for CIM-style motors
Shielded out-runner construction
Front and rear ball bearings
High-temperature neodymium magnets
High-flex silicone motor wires
Integrated motor sensor
3-phase hall sensors
Motor temperature sensor
A tapped #10-32 hole on the end of the shaft, allowing teams to retain pinions on the shaft without using external retaining rings
A tapped #10-32 hole on the back housing of the motor, making it no longer necessary to remove the motor housing to press pinions
Additional holes on the front face of the motor for added mounting flexibility
