# NEO Vortex

## NEO Vortex Overview

The [NEO Vortex Brushless Motor (REV-21-1652)](https://www.revrobotics.com/rev-21-1652/) is a high-power, high-performance, and high-resolution sensored brushless motor from REV Robotics. It features a dockable controller interface that can be mounted directly to the [SPARK Flex Motor Controller (REV-11-2159)](https://www.revrobotics.com/rev-11-2159/) or a [NEO Vortex Solo Adapter (REV-11-2828)](https://www.revrobotics.com/rev-11-2828/) allowing control from any brushless motor controller, like the SPARK MAX. Its through-bore rotor is the heart of its unique interchangeable shaft system, facilitating easy integration with various robot mechanisms.
