Product Overview

The CIM motor is a tried and true FIRST Robotics Competition workhorse motor. This brushed DC motor is 2.5 inches in diameter and kicks out 337 watts of power.

Pinion Options:
The CIM motor shaft is 0.313 in. (8mm) in diameter and 1.25 inches long. It features a 2mm wide machine key slot allowing installation of any number of custom or off the shelf pinions such as those included with all of our CIM based gearboxes. Other options include a pre-attached 16 tooth pinion making the CIM ready to mate to a CIM Sport planetary gearbox or a pre-attached 15 tooth pinion preparing the CIM for an EVO Gearbox. Use either of these two options if you are planning on using either the CIM Sport or an EVO gearbox and don't want to install the press fit pinion yourself. All of our other CIM based gearboxes use a slip fit pinion & machine key and are easy for the end user to install.

    An Excellent Motor

    This motor is a very good choice for any team and any skill level. The motor is powerful enough that two of them can move the entire robot quite quickly. As stated in the title, this is an excellent motor.

    "Reliable, and Perfect for FRC"

    "This motor may not be ideal for cooling, but it has more than enough heat capacity to last a whole match under decent load. Very reliable motors. We have gotten a couple pinions stuck on shafts, but that's our fault. Now, we have gotten the same power out of a 550 size motor, but that required some pretty crazy cooling, and had poor reliability. These are hands-down renowned motors."
