Power, CAN, and USB-C connections are on the motor. See Wiring for the connector locations.

Using Cyclone on your robot

Cyclone combines a brushless motor, motor controller, and 14-bit absolute encoder in one housing. Connect its red and black power wires to a breaker- or fuse-protected output on the robot’s power distribution hub. Plug its supplied CAN connectors into the robot’s CAN bus loop. CAN H is yellow and CAN L is green. Your robot program sends commands and reads measurements over CAN.

SWYFT Link runs on SystemCore and provides configuration, device identification, live measurements, and firmware updates. USB-C connects your laptop directly to a Cyclone for setup, updates, or motor testing before CAN is connected. Running the motor requires 12 V battery power; standalone USB-C testing does not require SystemCore or Driver Station. If a robot signal is also present over CAN, Driver Station permission still applies.

  • Duty, velocity, and position control through the Java API
  • Adjustable limits for current inside the motor (stator) and current drawn from the battery (supply)
  • Temperature protection and reported fault states
  • Shaft angle measurement and a count of complete turns since power-up
  • Two status lights and five user-controlled lights

Getting started

  1. Mount and wire the motor. Follow Mounting and Wiring.
  2. Open SWYFT Link on SystemCore. Identify each Cyclone and assign a unique device number.
  3. Set current limits for the mechanism, then follow First power-up.
  4. Add the Java library to your robot project and send commands from your periodic control code.
