Core Hex Motor

Core Hex Motor Basics

The Core Hex Motor (REV-41-1300) is a motor that features a 90 degree orientation and a female output shaft for maximum flexibility and ease of use. Insert any of the REV standard 5mm Hex Shafts into or through the Core Hex Motor to create custom length motor output shafts. The Core Hex Motor has a built in magnetic quadrature encoder which is compatible with 5V or 3.3V logic level devices including the Control Hub (REV-31-1595) and Expansion Hub (REV-31-1153).


The Core Hex Motor uses a 2-pin JST-VH Connector for motor power and a 4-pin JST-PH for sensor feedback from the built-in encoder. For more information on using the cables and connectors included with the Core Hex Motor, see the REV Control System - Cable and Connectors documentation. The image below has the pinout for the motor power and the encoder.

How to Mount the Core Hex Motor

The Core Hex Motor has two faces for mounting on two sides of the motor. The combination of the Motion Pattern is clocked to different angles on each face giving twelve different motor angles. The images below exhibit a basic mounting structure for two of the twelve positions that are available.

The images show a very basic mounting system. It is always advised to properly support elements of your robot with more 2 or more plastic brackets
