Successful Development of New Ultra Energy Efficient Magnetic Ribbon SENNTIX III

NEC TOKIN Corporation (President: Masakazu Okabe; Head office: Sendai, Japan) has developed a new energy efficient magnetic ribbon named "SENNTIX III*" jointly with Professor. Akihiro Makino of the Institute for Materials Research, Tohoku University, based on Prof. Makino's research. This revolutionary new material has the potential to greatly improve the power consumption of motors used in electric cars, and mid-sized and larger transformers used in electric power grids. Samples will be supplied starting this fiscal year.

This newly developed magnetic ribbon SENNTIX III enables to minimize the loss generated in the magnetic core (iron loss), which is a cause of loss in devices with high energy consumption, such as motors and transformers. SENNTIX III has been composed with Ubiquitous elements only and its iron proportion exceeds 90%. This makes it an Earth-friendly material that can be supplied stably at low prices.

SENNTIX III is the nanocrystalline micro-structured material (see Photo 1) with extremely low loss characteristic in the range of the saturation magnetic flux density over 1.8T (Tesla) discovered by Prof.  Akihiro Makino. NEC TOKIN has conducted joint research with Prof. Makino to commercialize this revolutionary new material.

Over the past few years, there has been rapid growth in development of alternative forms of energy to fossil fuels. While use of solar and wind power has advanced, electric power grids have started being converted into smart grids, and electric vehicles (EVs) equipped with high-capacity batteries have also reached the level where their widespread adoption is possible. Although these technological innovations are effective at reducing emissions of greenhouse gases, which are believed to be a cause of global warming, a major breakthrough is still needed strongly in the effective utilization of energy, or in other words, reducing the energy loss of devices that use electricity.

The global electric-power consumption is currently 19,771 TWh (results from 2007), of which 672 TWh (3.4% of the total power consumption) is wasted as heat energy caused by iron loss** when motors and transformers consume power. Minimizing this loss will make that amount of power consumption unnecessary, which would significantly reduce carbon emissions.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
