Kollmorgen has launched its AKMA servo motor built specifically for durability, cleanability, and versatility. The motor employs a hardened anodized aluminum surface to offer machine designers a cost-effective hygienic option to stainless steel in medium to heavy washdown applications. The lightweight design of the AKMA motor makes it easy to install and maintain, and its […]
When is it time to switch to a servomotor?
The unpredictable global economy has derailed formally reliable supply chains, causing extra stress on both established products and systems currently in development. Prior to 2018, many engineers selected motors and motion control options based on what they used in the previous machine design. Today, engineers have the burden of factoring in product availability and price […]

Delta Line has been in motion control for more than 40 years and has first-hand experience garnered from its popular brushless slotted motor line. Flexible, configurable, and price-practical, these servo […]
Where brushless servo motors have the edge
While there are many motor types to choose from, brushless servo motors have some advantages that make them the motor of choice in many applications. Bob Merrill Product Manager Servo motors ABB There are many motor types out there for engineers to choose from, and which is the best selection depends on each individual application. […]
Brushless ac servo motors are IP67 sealed, feature Mil-Spec rating
Kollmorgen’s new EKM series of enhanced, high-performance, brushless ac servo motors are Mil-Spec 810E rated and IP67 sealed for duty in harsh environmental conditions. They are supplied standard with a stainless-steel shaft and chemical agent-resistant paint for reliable duty in harsh environmental conditions. The EKM brushless servo motors feature high power and torque density and […]
What are biquad and other filter types for servo tuning?
One way to improve servo system performance is to increase the gains in the control loop, allowing the system to respond faster to commands and to settle more quickly, with less oscillation. But increasing the servo gains means that any resonances in the system — typically due to mechanical compliance — are further amplified, which can […]
What is external device monitoring and how does it relate to machine safety?
According to the Machinery Directive 2006/42/EC, technical protective measures should be used to reduce risks that cannot be avoided through safe design measures. These technical protective measures include safety devices such as door locks, covers, light curtains, and other equipment that monitors the machine movements. When the safety device controls and external device, such as […]
What machine safety functions address speed, and when are they used?
The Machinery Directive 2006/42/EC states that when a machine manufacturer is unable to eliminate the risks of potential hazardous situations (for example, mechanical hazards such as crushing or cutting) through safe design methods, the next step is to reduce the risks through technical protective measures. These technical measures include protective devices, such as door locks […]
STXI Motion expands integrated closed-loop servo-stepper motor line
The stepIM NEMA 17 EtherCAT model from STXI Motion is the newest addition to the company’s family of integrated closed-loop servo stepper motors. The IP65-rated stepIM NEMA 17 delivers an efficient and economical solution for applications requiring the performance of a servo at the price of a stepper. “The new stepIM NEMA 17 closed-loop stepper […]
Which types of DC motors can be used as servo motors? (And a refresher on DC motor technologies)
Servo motors are used in applications where precise control of position, speed, or torque is required. But many different types of motors can be considered servo motors — the defining feature of a servo motor is that it incorporates or reads feedback in a closed-loop system. In fact, although many servo applications use synchronous AC motors, […]
