AC PM Servo Drive Amplifiers: Different Servo Motor Phase and Commutation Alignments
The issues with commutation alignment between servo motors and servo drives, especially when the motor and drive are from different manufacturers, can be quite challenging. Understanding typical design challenges can help you tackle motor phase-sequencing issues. We will start by identifying or confirming the servo motor’s leads. Then we will move to identifying the...
SPINEA Plays a Central Role in Transforming the World’s Cities
Global human population is rising at a rate of about 1.1% a year and urban centers, which receive the bulk of that growth, are reaching the limits of what today’s technologies and organizational structures can deal with. Seventy percent of climate-changing emissions come from cities, and traffic congestion is reaching intolerable levels. Public...
Managing PM AC Servo Motor Overloads: Thermal Time Constant
When intermittent power demands are high for an extended time, classic RMS calculations and speed-torque performance curves may not be enough for proper servo motor and drive selection. Considering thermal time constants is essential to prevent undersizing and overload. This paper explains how to incorporate thermal time constants to reduce the risk of under-sizing...
The Resonance: Mechanical Resonance in Precision Engineering – SPINEA
Resonance has several definitions. From a physical perspective it is a simultaneous oscillation caused by waves tuned to the same period impinging on a body or the ability of a body to oscillate to the same frequency as the source. Another definition again states that resonance is the tendency of a system to oscillate at a greater amplitude, at some frequencies more...
Kollmorgen helps packaging automation solutions provider meet the need for on-demand “right-sized” packaging
In recent years, e-commerce and global logistics have grown tremendously—with demand often outpacing capacity. Labor shortages, supply chain disruptions, increased competition and cries for sustainability further increase the pressure. Large retailers that ship a wide variety of products have found themselves at a crossroads: Find ways to innovate fulfillment and...
