How do you combine your favourite motor with igus linear axes?

The precise igus linear axes offer numerous options for individual drive solutions. The electrical integration via motor is particularly intriguing. A toothed belt or a lead screw in combination with our tribologically optimised high-performance plastics mechanically transmit the drive forces. These are generated via muscle power and a hand wheel, or electrically with a motor. The latter will be discussed in more detail here. Although igus offers a wide range of motors, there are always very specific requirements for which there is no immediate solution. To support prototype construction and the production of small batches, we offer prefabricated motor flanges that match your motors.

How is a motor flange constructed?

Our motor flanges always consist of two parts: the base holder, which provides stability and correct alignment, and the motor plate, which ensures the correct screw-on dimensions.

Motor flange with lead screw axis as basic holder

Here, the basic holder consists of a flanged bell in which the coupling for the mechanical connection of lead screw and motor shaft disappears. For a customer-specific motor flange, the basic holder (the flange bell) remains the same here. Only the motor plate is adjusted.

Motor flange with toothed belt axis as basic holder

In principle, the motor flange of the toothed belt axis has the same design. Here, the basic holder grips right into the axis and bends the motor by 90° to the axis direction. In this way, we ensure that the motor shaft and the axis drive shaft are opposite each other. The basic holder is available in different lengths, so that even longer motors can be flange-mounted. The motor plate also provides the appropriate screw-on dimensions here and is adapted to the customer-specific motors.

Connecting a motor with linear axes: what technical data is important?

Ideally, the original data sheet of the motor is provided, including the exact name or part number of the desired motor. The data sheet should contain at least the following information:

Mounting hole circle diameter and mounting thread
Centring diameter and height
Distance over hubs
Length of the motor shaft
Diameter of the motor shaft

What does it cost?

As a rule, we manage to realise a price of £50 to £150 for one piece. In individual cases these prices may vary. For larger quantities >100 the price will not differ noticeably or not at all from the standard axis price.
