When we think of stiffness, we often think of mechanical stiffness — the ability of a part or system to resist deflection. But in servo-driven motion systems, stiffness can also refer to how the system is tuned — that is, how the gains in the servo controller are set and, correspondingly, how the motor responds […]
Servo Motors
What is a motor choke and why is it used?
A choke is a passive device that adds inductance to a circuit. Inductance is a property of a coil of wire that resists any change to the current flowing through it. (Straight wires also possess a small amount of inductance.) In other words, if current through the coil increases, the magnetic field of the coil […]
What is a motion profile?
Servo applications require defined, controlled movements, often to move a part to a specified position at a precise velocity or along a predetermined path. A motion profile provides the physical motion information and graphically depicts how the motor should behave during the movement (often in terms of position, velocity, and acceleration) and is used by […]
Integrated motors ensure reliability in high-acceleration food & beverage machines
Applied Motion Products offers StepSERVO Closed Loop Integrated Motors for closed-loop servo control of position, velocity and torque resulting in higher acceleration rates and faster machine cycles in food & beverage applications. Combining a high-torque step motor with an on-board drive, encoder, controller and closed-loop servo software into a single package, the integrated motors save […]
What is hunting in the context of motion control and how is it addressed?
When a linear or rotary axis must follow a predefined move profile to reach or maintain a precise position, speed, or torque, a closed-loop servo system is often the best choice. Feedback from an encoder — mounted on the motor or directly on the axis — provides information regarding the system’s actual state (position, speed, […]
Kollmorgen showing motion innovations at PACK EXPO 2019
Kollmorgen will exhibit its industry-leading motion control technology (including exciting new products) at Pack Expo in Las Vegas on September 23 to 25.

Getting servo motor and drive phase and commutation alignments right
Addressing issues related to commutation alignment between AC PM servo motors and servo drive amplifiers — especially when motor and drive are from different manufacturers — can be quite challenging. Here we outline how to make that easier. By Hurley Gill • Senior applications and systems engineer | Kollmorgen In this article, we’ll start by confirming […]
