Kollmorgen PMX Series Stepper Motors

The Kollmorgen PMX Series Stepper Motors are hybrid stepper motors, providing a competitively priced and comprehensive solution for simple open-loop motion control. They have two windings that use a DC current and have been designed with versatility, easy-of-use and cost effectiveness in mind. They provide high torque and come in a wide range of sizes, constructions, windings and options.

What does a PMX Series Stepper Motor do?

With six NEMA frame sizes including 08, 11, 14, 17, 23 and 34 each stepper motor in the PMX series provides several stack-length options and deliver holding torque from 2.8 Ncm to 11.4 Nm. The newest of the frame sizes, 08, 11 and 14, allow high quality miniaturised motion solutions with the same high standard and precision of the larger frame sizes.

They offer a number of standard options including bipolar and unipolar windings, integral connectors, shaft flats, keyways, rear shafts and IP65 sealings.  They also have the ability to move in very small, very precise increments making them perfect for high precision application requirements.

PMX Series Stepper Motor Applications

PMX Series Stepper Motors are suitable for applications requiring:

  • Positioning – as all steppers move in precise repeatable steps they are beneficial for in applications requiring precise positioning.  These include 3D printers, cutting machines, camera platforms and X,Y Plotters.
  • Speed Control – with precise increments of movement the PMX stepper motors offer excellent control of rotational speed for process automation and robotics.
  • Low Speed Torque – PMX stepper motors have maximum torque at low speeds and so they are an excellent option for applications that require low speed with high precision.

The PMX motor range is supported with a wide range of compatible stepper drives and single or multi-axis motion controls, from simple step and direction models to high performance EtherCAT and CANopen networked variants.
