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

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
Motor Generator Set (MG set)
Motor Generator Set are a combination of an electrical generator and an engine mounted together to form a single piece of equipment. Motor generator set is also referred to as a genset, or more commonly, a generator.Motor generator sets are used throughout industry to provide electrical power on demand. Typical applications include emergency power backup applications for the medical industry, remote sites, or any industrial or commercial application requiring an independent or remote power source. Motor generator sets are available in most standard power delivery configurations. Power plant i
Calibrating HART Transmitters
Abstract In order to take advantage of the digital capabilities of HART transmitters, especially for reporting process data values, it is essential that they be calibrated correctly. This paper outlinesthe differences between calibrating a conventional and a HART transmitter, and gives recommendations for calibration practices.Introduction This paper assumes that you want to make use of the digital process values that are available from a HART transmitter. However, before examining calibration requirements, we must first establish a basic understanding in two areas: calibration concepts, and
HART: The Tutorial
HART® stands for:HIGHWAY ADDRESSABLE REMOTE TRANSDUCERHART® is an open protocol that was originally developed in the late 1980's by Fisher Rosemount to communicate with their range of Smart field devices. Over the years it has become a de facto standard for communicating with SMART devices in the Process industry. Over 100 manufacturers utilise the HART® protocol in over 560 different products, from simple temperature transmitters to gas detectors.The HART® protocol is a powerful communication technology used to realise the full potential of digital field devices whilst preserving the traditi
