Motor Glossary#
- Core Hex Motor#
The Core Hex Motor, sold by REV, is different from the standard RS-555 series motors that are generally used by FTC teams. It features a 90 degree orientation and does not contain an output shaft. Thus, teams will have to cut 5 mm hex shaft to length as needed. The Core Hex motor has a slow gear ratio (72:1), and is not as powerful as the RS-555 series motor.
Warning
We advise teams to go against the Basic Bot Guide provided by FIRST, as Core Hex Motors should NOT be used to power drivetrains.
