IQ Fortiq BLS42 modules are full servo motors built to maximize torque and speed output while minimizing motor vibration and footprint. Our unique hardware design and advanced calibration techniques have allowed us to create the most compact and power-dense industrial servo motors on the market.

These modules can be used in a wide variety of applications—from 3D printers to conveyor belts to robotic joints—and are ideally suited to replace both stepper motors and traditional servo motors. They are intended for industrial machinery companies, research institutions, and individual makers alike. A Fortiq BLS42 motor offers the performance benefits of a high-end industrial servo at a price that is comparable to what you’d pay for a quality stepper motor and a controller. And it does so while occupying significantly less space.

Comparable Torque & Speed in a Smaller, Less Expensive Package

Fortiq BLS42 modules are around 55% more compact and 65% less expensive than traditional servos with similar torque and speed ratings. Many companies use industrial servos with optical encoders for position sensing, but optical encoders are bulky and expensive, so we replaced the optical encoder with a magnetic encoder to make the design more compact and less expensive.

Precision You Can Rely On

Our calibration algorithms make these motors extremely smooth and precise. Our encoder linearization algorithm, in particular, reduces typical magnetic errors by an order of magnitude. The Fortiq BLS42 modules have ±2 encoder tick accuracy. In addition, Fortiq BLS42 modules are able to maximize torque and decrease cogging torque ripple by 90% due to their straight stack, straight magnet motors and anticogging algorithm.

As Versatile as it is Practical

We are offering four different Fortiq BLS42 models, each with its own torque rating. Whether you’re trying to bring advanced, reliable motion control to a device that previously used steppers or trying to reduce costs by replacing an expensive industrial servo, the Fortiq BLS42 line will deliver exceptional results. Possible applications include:

3D Printers

3D printers typically use stepper motors for actuation. Steppers have high-torque output and are often a tenth of the price of industrial servos, which makes them well-suited for most 3D printers. High throughput is a key metric for 3D printers, however, and stepper motors are unable to spin quickly without a significant reduction in torque and a high risk of position loss. Our Fortiq motors—which are also capable of endstop homing without limit switches—are smoother and more efficient than steppers.

Fortiqs will never skip a step or get lost:

Stepper motors are quite loud. Our motors are silent:

CNC Machines

Mills, lathes, and routers typically use both servo and stepper motors. High-end machinery that requires precision, speed, and torque use expensive servos. IQ offers a more compact and cost effective alternative to traditional industrial servos. You can replace both expensive servos and cheap steppers with Fortiq module.

Conveyor Systems

Because they need to operate smoothly under large inertial loads, conveyor belts rely on industrial servo motors. Fortiq modules are ideal for belt mechanisms, as they provide consistent torque characteristics at low speeds and at high speeds.

Robotics

Robotic systems demand high performance in extremely small packages. Whether you’re building an Automated Guided Vehicle (AGV) or a robotic arm, you can use Fortiq motors to optimize for power density, precision, and smoothness.

Maker Projects

The diversity of the IQ Fortiq BLS42 line makes it perfect for projects and prototypes. With four different sizes and four different torque levels to choose from, these motors are suitable for a wide range of applications. We can’t wait to see what you build!
