# NEO Vortex Brushless Motor — REV-21-1652
|
|||
|
|
|
|||
|
|
## Overview
|
|||
|
|
|
|||
|
|
The **NEO Vortex** is Team 2890's standard drive motor for swerve modules. It's a high-power sensored brushless motor with integrated encoder memory and a dockable interface that connects directly to the SPARK Flex motor controller.

|
|||
|
|
- Integrated motor parameter and calibration memory (auto-configures with SPARK Flex)
|
|||
|
|
- Dual sensor direct-contact winding temperature sensing
|
|||
|
|
- No motor wires — reliable dock connectors for phases and sensor
|
|||
|
|
- Through-hex bore for quick-change shaft system

## Connection to Training
|
|||
|
|
|
|||
|
|
**For students:** The NEO Vortex is the power plant. Understanding:
|
|||
|
|
- **Kv rating** (565 Kv) — at 12V, spins at ~6784 RPM under no load
|
|||
|
|
- **Stall vs. free speed** — torque is highest at stall, speed is highest at no load
|
|||
|
|
- **Current draw** — 211A stall means the battery and wiring must handle high current surges
|
|||
|
|
- **Temperature sensing** — dual sensors protect the motor from overheating
|
|||
|
|
|
|||
|
|
This is a good bridge between physics (Pmec = τ × ω) and real hardware.

## Notes
|
|||
|
|
|
|||
|
|
Chris and team use these with SPARK Flex controllers in the MK4i swerve modules. The dockable design eliminates external motor wiring — phases and sensor data pass through the dock connection. This is a significant reliability improvement over bullet-wire connections.
