V5 Smart Motor (11w) Update

VEX has confirmed that there is a manufacturing error in a small run of V5 Smart Motors (11W). This only applies to a small production run of the Rev 10 version of motors (more details below).

  • Under normal circumstances, all Rev 10 motors will perform correctly and not fail.
  • Affected Rev 10 motors will only fail when used in Voltage Mode and commanded to run higher than 11V and then commanded with a reverse in direction.
  • Affected Rev 10 motors will not fail if you avoid Voltage Mode.
  • See this VEX Library Article on how to protect Rev 10 motors with code.

VEX’s Corrective Action

  • VEX will replace failed and functional Rev 10 motors at no cost to you.
  • VEX will pay for shipping both ways.

  1. For working motors
    1. Run the program at to see if your motor is Rev 10.
  2. For failed motors
    1. Failed motors will not have a red light on the smart port when connected to a powered V5 Robot Brain.
    2. Locate the date code on your motor (see image to the right).
    3. If the first four digits of the date code is “2143” or higher it is possible that this motor is a rev 10 and can be returned.
