IQ Fortiq Modules are now compatible with NEMA mounting standards!

by Jon B

Due to a number of requests, IQ is redesigning the Fortiq’s mounting holes to match the NEMA 17 standard. Please see the updated drawing below. This new drawing will be reflected in IQ’s datasheets in the next week.

NEMA is a US-based association that sets manufacturing standards based on a consensus from manufacturers. Industrial standards are in place to give mechanical designers confidence they’ll be able to use off-the-shelf parts without the need for significant customization.

NEMA 17 motors have a 31 mm hole pattern, while the Fortiq BLS42s previously had a 25.4 mm hole pattern, which is the standard for BLDC servomotors in certain parts of the world. In order to achieve our goal of replacing both stepper and servo motors with the Fortiqs, we decided it was best to change to the more common NEMA standards.

We greatly appreciate feedback from our backers that helps us make this product a better drop-in replacement for NEMA 17 stepper motors. If you were planning around the previous hole pattern and this change will be a problem for you, please reach out to us as soon as possible. We will work with you to deliver a product that works for your application.
