NEO Vortex & SPARK Flex

NEO Vortex and SPARK Flex


Unleash Versatility in Every Rotation with the Next Generation of Motors and Controllers

NEO Vortex, 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 or a standalone adapter 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.

Highlighted Features:
  • High resolution encoder
  • Integrated motor parameter and calibration memory
  • Through-hex bore with taper for numerous quick-change shafts
  • No motor wires - reliable and robust docking connections for motor phases and sensor
  • Dual sensor, direct contact winding temperature sensing
  • 560KV (RPM per volt)
  • 640 Watts (375 @ 40A)

SPARK Flex, a new smart motor controller from REV Robotics. Its dockable form factor allows for the direct mounting onto a NEO Vortex, simplifying wiring while maintaining flexibility. Improving upon the foundation of the SPARK MAX, new features include 3-phase current sensing, reverse polarity protection, and an expanded data port with additional interfaces. When docked to an adapter, the SPARK Flex can control any existing NEO or compatible brushless/brushed DC motor.

Highlighted Features:
  • Docking interface for motor phases and sensors 
  • USB type C configuration and control
  • PWM and CAN communication
  • Fully integrated power and control wires
  • Enhanced data port with more power, latching connector, and additional serial interfaces
  • Advanced motor control modes
    • Velocity
    • Position
    • Current
    • New modes with future firmware updates
  • 3 phase current shunt measurement
  • Reverse polarity protection
  • Software
    • Configure and update through REV Hardware Client
    • Updates and new features are free forever, without subscriptions or licenses
