Motors and Drives Basics

Selecting the right motor and drive combination can save energy and improve performance.The venerable electric motor that was the muscle of the industrial revolution is becoming the smart muscle of the computer-controlled plant and commercial facility of the future. The advent of powerful, reliable electronic drives is keeping motors in the forefront of this technological evolution.Electric motors have a tremendous impact on overall energy use. Between 30 to 40 percent of all fossil fuels burned are used to generate electricity, and two-thirds of that electricity is converted by motors into m

ELECTRIC MOTOR CONTROLS Part 1

Once the proper motor is selected, understanding the many various control devices available andtheir uses and limitations becomes an important part related to reliable operation and protection of the motor and the personnel using the motor.Motor Control TopicsThere are four major motor control topics or categories to consider. Each of these has several subcategories and sometimes the subcategories overlap to some extent. Certain pieces of motor control equipment can accomplish multiple functions from each of the topics or categories.The four categories include:1) Starting the Motor Disconnect

What is Industrial Ethernet?

Industrial Ethernet OverviewThe Ethernet network is a local-area network (LAN) protocol developed by Xerox Corporation in cooperation with DEC and Intel in 1976. Ethernet uses a bus or star topology, and supports data transfer rates of 10 Mbps (standard) or 100 Mbps (using the newer 100Base-T version).The Ethernet specification served as the basis for the IEEE 802.3 standard, which specifies the physical and lower software layers. Ethernet uses the CSMA/CD access method to handle simultaneous demands. It is one of the most widely implemented LAN standards.OSI Reference ModelDeveloped by Inter
