Why is RMS current important in stepper motor applications?
Most precision stepper motor applications — especially those in automation and motion control — use a control method referred to as microstepping, which creates a sinusoidal (or nearly sinusoidal) current waveform, rather than the square wave of current produced with typical full-step control. The current rating of a stepper motor depends on the amount of […]
AutomationDirect adds new servo systems for motion control applications
AutomationDirect has added LS Electric servo systems that provide extremely accurate motion control and include the most requested features — setup wizards, auto-tuning, built-in indexer, and more — in an extremely cost-effective package. The L7S family of brushless servo systems is fully digital and capable of covering a broad range of motion control applications. There […]
How do manufacturers address cogging in linear motors?
Iron core linear motors are known for their high continuous and peak force capabilities, good thermal management, and excellent force-to-size ratio. But they’re also known to produce cogging forces, which lead to force ripple, or variation in output force. But how much of a problem is cogging for iron core linear motors, and what are […]
ABB introduces the third generation of Baldor-Reliance RPM AC motors
Baldor-Reliance Generation 3 RPM AC motors deliver 1 to 1,750 hp, with customizable speed ranges in nearly any enclosure type. The motors are designed to handle the most demanding applications in industries such as chemical, oil and gas; plastics; HVAC; energy; forest products; metals and industrial automation. RPM AC motors are optimized for adjustable frequency […]
ATEX and IECEx classifications and markings explained
When electrical equipment is used in a potentially hazardous location — one that contains flammable gases, vapors, liquids, dust, or fibers — it’s important that the potential for fire or explosion be minimized. One way to do this is to use equipment that has been certified as suitable for that environment and not likely to […]
What are harmonics and how do they affect motion control systems?
Harmonics are voltages or currents caused by non-linear loads on a power supply. Harmonic frequencies occur at integer multiples of a fundamental frequency and are superimposed on the fundamental voltage or current waveform, creating a distorted waveform. Harmonics are classified first by their order, or the integer multiple of the fundamental frequency. For example, for […]
