Fortiq BLS42: Feature Updates
Due to a number of requests, Vertiq is redesigning the Fortiq’s mounting feature to match the NEMA 17 standard. Please see the updated drawing below. This new drawing will be reflected in Vertiq’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 machine designers the confidence that 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.
Vertiq has also incorporated the Anticogging algorithm, one of its most prominent features, into the Fortiq. Cogging torque ripple causes motor vibration which in turn makes machines noisy and imprecise. By reducing cogging torque by 90% with Anticogging, Vertiq makes machines much smoother and quieter without compromising performance. Watch our AntiCogging algorithm in live action below!
For devices like 3D printers and CNC machines, motor vibration results in noisy operation and lower quality manufacturing. Anticogging addresses these issues. The Fortiqs also have a small motor/controller footprint and precise positioning capabilities, making them an elegant alternative to clunky stepper motors and a much cheaper solution compared to standard industrial servos.
