Arnold Magnetic Technologies Non Grain Oriented (NGOES) Electrical Steel is optimized by thickness and finish to meet your most demanding needs for high speed, high efficiency motors and high efficiency transformer applications. When optimally applied, NGOES offers reduced eddy currents which translate into energy savings.<\/p>\n\n\n\n

SMALLER, LIGHTER, MORE EFFICIENT MOTORS AND GENERATORS<\/h2>\n\n\n\n

Arnold\u2019s Non Grain Oriented Electrial Steel (NGOES) is manufactured in thicknesses of 0.004\u2033, 0.005\u2033 and 0.007\u2033 (0.102mm, 0.127 mm and 0.178 mm) under the trade names Arnon\u2122 4, Arnon\u2122 5 and Arnon\u2122 7. Typical NGOES electrical steel laminations use 0.0118\u2033 to 0.0185\u2033 (0.30 mm to 0.47 mm) thicknesses.<\/p>\n\n\n\n

Arnon\u2122 silicon steel is frequently used as laminations in high speed, high efficiency motors and generators. Whereas common laminations use 0.014\u2033 to 0.032\u2033 (0.356 mm to 0.813 mm) thicknesses, Arnon 5 and Arnon 7 are thinner at 0.004\u2033, 0.005\u2033 and 0.007\u2033 (0.102mm, 0.127 mm and 0.178 mm) respectively. The laminations are located in either the rotor or the stator depending on whether the laminated structure is used in a rotating or stationary design. The laminations are generally made from NGOES since they are circular and the magnetic properties are equal in all directions.<\/p>\n\n\n\n

By using thinner laminations, your high speed motor and\/or generator can achieve a higher level of performance through improved efficiency.<\/p>\n\n\n\n

Arnon electrical steel has shown to be particularly advantageous for higher frequency motors and generators above 400 Hz. In these designs, the thinner material offsets the less efficient effects of increased eddy currents and subsequent heat buildup. Using thin laminations of Arnon produces a more efficient unit and frees up design constraints by allowing for fully enclosing the motor without external cooling, for example. Arnon laminations have proven to be the industry leader at switching frequencies above 1K Hz.<\/p>\n\n\n\n

Arnon has the ability to lower core loss by as much as 50% compared to other NGOES materials. Some motors using Arnon have been tested to exceed 98% efficiency.<\/p>\n\n\n\n

These materials are produced using our proprietary process that begins by rolling a heavier gauge 3% silicon steel Grain Oriented Electrical Steel (GOES) to the required thickness and then \u201cunorienting\u201d it. This unique process creates a thin gauge steel with superior properties for use in Industrial, Aerospace, Defense, Semiconductor, and Medical applications.<\/p>\n\n\n\n

WHY ARNON?<\/h3>\n\n\n\n

Thin gauge Arnon provides efficiency improvements at higher frequencies above 400 Hz with exponential efficiency gains as the frequency increases.<\/p>\n\n\n\n
