If your ultimate goal is to bring product to market faster, make sure you have a basic understanding of motor control strategies. Motor drive upgrades are an easy way to boost plant performance, provided you select the appropriate drive technology. This industrial motor control overview, authored by a Lenze application engineer, explains how advanced variable frequency drives with sensorless vector technology offer "virtually limitless design possibilities." In addition, the article addresses the related topics of NEMA-rated asset protection and integrated communication protocol.

Our ARKTIC SSC unit bearing motors are primarily used in commercial refrigeration evaporator fan applications, but can be used in many applications demanding high efficiency and dependability with output ratings between 2-38 watts.

Across the European Union, general-purpose AC motors installed from June must meet a minimum efficiency of IE2, the equivalent to the previous CEMEP EFF1 standard. According to this piece from EngineeringTalk, "most OEMs currently use lower-efficiency EFF3- or EFF2-grade AC motors." Here is some straight talk about transitioning to minimum electric-motor efficiency levels.

Though considered a workhorse of industry, the AC induction motor is not perfect. Slip-induced speed error, for instance, can hurt the quality and accuracy of motor/drive applications, especially when motors of different sizes are connected mechanically. This Plant Services tutorial explores strategies to control motor slip, including adjustable-speed AC drives, vector, and direct torque control.

When the temperature falls to -100 F, the last thing a technician needs to worry about is motor maintenance. While scientists working at Concordia Station in Antarctica are used to extreme cold, they are grateful for the highly reliable motors driving the station's quarter-ton telescope. Thanks goes to the motors' ironless core, graphite or precious metal brushes, and special bearing grease — all described in this interesting story.

Intended for DC motors rated to 2 hp, this compact speed control stores custom settings and provides programmable power-on initial settings. Another feature: digital closed-loop feedback. Speed feedback capacity is 50,000 pulses per minute (833 Hz). Any Engineering unit of measure can be displayed.

ARC Systems' high-performance brushless DC motors are ideal for servo drives in motion control applications. ARC's designs feature high torque to inertia ratios. They have the experience and the engineering expertise to meet virtually any motion control application. Learn more about ARC Systems, Inc.

Kollmorgen introduces its Platinum U Series of high-performance pancake servo motors. The Platinum U Series motor provides excellent acceleration/deceleration, zero cogging at all speeds, is up to 40% lighter than conventional pancake motors, and much more. Distributed by Electromate.

Permanent magnet, synchronous torque motors can be found in a wide range of machinery, from packaging and converting equipment to injection molding and machine tool operations. Providing high torque density in a small footprint, torque motors also offer direct load control, low maintenance, and exceptional energy efficiency. This article from Siemens argues their case.

The tooling changeover times needed to switch from one product SKU to another forced one supplier of packaging automation to take action. As this case history describes, machine adjustments previously made by air motors and hand cranks are now accomplished with servo motors. Specifically, stock servo actuators modified with an absolute encoder and DeviceNet chip. Now, changeovers take minutes instead of hours.

Meeting new efficiency requirements involves more than selecting a motor that is labeled "energy efficient." As this report clearly explains, that's just "part of the puzzle." The report debunks some common motor efficiency misconceptions and lays out an efficiency strategy that incorporates all elements of the drivetrain.

Detailed examples from leading manufacturers highlight the paths leading to ever higher motor efficiencies. These include the availability of better materials, advanced magnet technologies, and new methods for assembly. If you thought motor technology was standing still, think again. Companies featured include Oriental Motors, Delta Tau, Yaskawa America, and Baldor Electric.

At SEC Electric Machinery Company, a slip ring motor manufacturer and supplier based in China, we primarily produce slip ring wound rotor three phase asynchronous electric motors, or simply slip ring asynchronous motors, which can be used for driving or towing rolling mills, fans started with heavy loads, etc.

Plant maintenance personnel have it good these days. Thanks to the Internet and other tools, the job of keeping motors and drives running efficiently has become more interesting, more personal, and even easier. This commentator explores online options, reviews some popular hands-on programs, and looks at how the two training techniques— online and hands-on — impact each other.

Simple physics amazes 90% of the general public. Display your "genius" with this quick-and-easy demo. Only three parts are needed: a battery, magnet, and piece of copper wire. If you employ terms like "homopolar" and "axis-of-rotation" to explain the phenomenon, your geeky legacy will be sealed.

Are Fixed-speed Motor Drives Obsolete?

If your ultimate goal is to bring product to market faster, cheaper, and more efficiently, why would you specify a fixed-speed motor drive?
