Stepper motors divide a full rotation of the rotor into a number of equally sized “steps,” offering the ability to quickly position a load and hold it at any one of these steps. Also known as step motors or stepping motors, these brushless DC motors offer quick, precise positioning and exceptional holding torque. Stepping technology allows for the use of an open-loop controller – simplifying machine design and lowering total cost compared to a servo motor system.
Our high-performance, brushless, maintenance-free stepper motors provide precise, extremely cost-effective motion control. These 2-phase motors inherently move in exact 1.8° increments (200 steps per revolution), with no need for expensive, complicated feedback devices. When using a microstepping drive, each 1.8° step can be broken into even smaller increments to achieve nearly servo-like positioning performance.
Kollmorgen offers a wide range of standard sizes, constructions, windings and options including custom leads, shafts and connectors. And our advanced hybrid stepper motor technology is unequalled – incorporating large bearings, high-voltage insulation, large rotor diameters, tight air gap tolerances, and high-energy magnets and windings that other manufacturers don’t offer.
Our NEW stepper motor optimizer tool, Stepper Optimizer provides multiple ways for you to discover what Kollmorgen step motor works best in your application. Browse our step motor catalog and discover which motor frame size will fit your application, and then modify the available voltage and current to match your stepper drive configuration. You can also use our Application Sizing section to find the best solution that fits your application requirements. Determine a solution by identifying your required torque and speed or through identifying your basic motion profile. The tool takes into account not only your available voltage and current, but considers your duty cycle, on time, ideal current reduction and current reduction delay.
For an even smaller, faster and more energy-efficient machine, choose an enhanced stepper model featuring SIGMAX® technology. Our patented design focuses magnetic flux more efficiently to provide 25 percent more torque across the entire speed range. With SIGMAX technology, you can get the torque you need with a smaller drive and lower power consumption – so your machine is smaller, faster and more affordable to build and operate.
