How To Mount A Motor Onto An igus® Linear Actuator

Igus® manufactures a wide range of linear actuatorsscrew driven, belt driven, or electric, and built in combination with our tribologically optimized high-performance plastics. The driving force can be generated through the use of human muscle power via a handwheel, or electrically via a connection with a motor. In this post, we’ll be taking a closer look at the latter option and discussing both igus® produced motors, as well as others. Igus® currently offers a diverse range of electric motors, but there are still certain requirements that we cannot meet on demand. So, in order to support prototyping and small series production, we offer prefabricated motor flanges that will adapt to your motors.

How is a motor flange constructed?

Our motor flanges are always built in two parts—the basic bracket, which ensures stability and correct alignment, and the motor plate, which ensures the appropriate screw-on dimensions.

Motor flange with a screw-driven actuator as a basic frame

In this type of design, the basic frame consists of a flange bell where the coupling that connects the lead screw and motor shaft is hidden. For a customer-specific motor flange, the basic frame (the flange bell) remains the same and only the motor plate is adjusted.

Motor flange with belt-driven actuator as basic frame

The motor flange of a belt-driven actuator is essentially the same—the basic holder grips directly onto the actuator and bends the motor 90° in the direction of the actuator, ensuring that the motor shaft and the final drive shaft face each other. The basic holder is available in different lengths so that longer motors can also be flanged on. The motor-plate also ensures the appropriate screw-on dimensions and is adaptable for customer-specific motors.

What technical data is required?

If possible, provide the original data sheet of the engine and the exact designation or article number of the new engine that you are considering. The data sheet should include:

  • Fastening bolt circle diameter and fastening thread
  • Centering diameter and height
  • Flange dimension
  • Length of the motor shaft
  • Diameter of the motor shaft

Now what?

At igus®, we will work with you and your application’s needs to find the best part possible, at the best possible cost. With a motorized linear actuator, you open up the door to a whole new realm of industrial possibilities and improvements that can benefit your customers.
