The Kraken X60 is an enclosed outrunner motor, just like other brushless motors of a similar size. The internal design of the Kraken X60 has a number of features to make it more robust and reliable. These features include:

## Larger Bearings

The bearings used inside the Kraken X60 were sized to better handle higher radial loads typically seen in FRC. In addition, all the bearings used in the Kraken X60 are rated ABEC-5 and spec'd to handle the heat that the Kraken X60 can produce. &#x20;

## Integrated Output Shaft

The output shaft of the Kraken X60 is integrated into the motor, and cannot be replaced.

There are also multiple methods of rotationally and axially constraining the shaft to the rotor. This creates redundancy with the idea that if one fails, there's another method to keep the motor running.&#x20;

## Less Drag

The internals of the Kraken X60 was designed to reduce the potential for mechanical misalignment of the shaft bearings. This design yields a motor with less mechanical drag, which improves the no-load performance of the motor and allows the motor to be more efficient overall. &#x20;

## Cooling

The Kraken X60 was designed to keep heat away from the back of the motor where sensitive electronics are mounted.&#x20;
