IQ Motion Control, a 2018 graduate of the HAX program, announced today the launch of their newest line of servo motors, the Fortiq BLS42. The ultra compact high performance servo motors offer performance benefits of high end industrial servos at a greatly reduced cost, and have wide ranging applications across 3D printing, CNC machining, robotics, and conveyor systems.

The new line of servos boasts impressive qualifications:

  • Rated to 4,000 RPM, with ±2 encoder tick accuracy, meaning a 90% reduction in cogging torque ripple with IQ’s calibration software.
  • Straight stack, straight magnet BLDC motor with an integrated motor controller and magnetic rotary encoder for position sensing.
  • 50% less volume and are 70% of the cost when compared to traditional industrial servo motors.
  • Four size options available for customers, each with a different torque rating dependent on stack length. 

The new line of motors are built to maximize torque and speed output, while minimizing motor vibration and footprint, and are currently available for pre-order on Crowd Supply.

The IQ Fortiq BLS42 is optimized for applications in 3D printing, robotics, CNC machining, and conveyor systems.

3D Printers

3D printers typically use stepper motors for actuation. Steppers have high torque output and are 10x cheaper than industrial servos, making them well-suited for most 3D printers. High through-put, however, is a key metric for 3D printers, and stepper motors are unable to spin quickly without a significant reduction in torque and a high risk of losing position. IQ’s Fortiq motors are smoother and more efficient compared to steppers, and they’ll never skip a step or get lost. The Fortiqs are also capable of endstop homing without limit switches and they’re silent. Print faster and more reliably with a Fortiq.


Robotic systems demand high performance in extremely small packages. So, whether you’re building an AGV or robotic arm, you can use the Fortiq to optimize power density, precision, and smoothness in your device. The Fortiq BLS42 motors are rated to 4,000 RPM, have ±2 encoder tick accuracy, experience a 90% reduction in cogging torque ripple with IQ’s calibration software, and have 50% less volume and are 70% less expensive compared to traditional industrial servo motors. There are also 4 size options available for users, each with a different torque rating dependent on stack length. 

CNC Machines

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

Conveyor Systems

Conveyor belts operate with industrial servo motors due to their need for smooth operation with large inertial loads. The Fortiq is ideal for belt mechanisms, as it has consistent torque characteristics from low to high speeds.
