Motors

The FRC motor lineup and why CIM-class mounting lets you swap motors without redesigning a thing.

What a Motor Does

Motors turn battery power into rotation.

  • They drive intakes, climbers, drivetrains — everything that moves.
  • FRC lineup: CIM, MiniCIM, Falcon 500, Kraken x60, NEO, NEO Vortex, Redux Cu60.
  • We run WCP, so Kraken x60 and NEO show up a lot.

The CIM-Class Standard

Most modern motors share one mounting footprint — the CIM class.

  • 2.5 in outer diameter (some 60 mm / 2.362 in).
  • #10-32 mounting holes on a 2 in bolt circle, 1 in from center.
  • Anywhere from 2 to 11 holes depending on the motor.

Key idea

Same mounting = swap motors without redesigning the bracket.

Design for the class, not the part number.

Recap

MOTORS

  • Motors turn battery power into rotation
  • CIM-class share a 2.5 in OD + 2 in bolt circle
  • #10-32 holes, 1 in from center
  • Design to the class so motors swap freely
