Toroidal amorphous and nanocrystalline MSTATOR cores

mstatorOJSC MSTATOR has been developing and producing alloys with an amorphous and nanocrystalline structure for 30 years. A detailed information on material characteristics produced by MSTATOR is represented in the section "Characteristics of amorphous and nanocrystalline AMAG alloys".

At this moment the company has a full range of modern equipment and technologies allow to produce a fairly wide range of products. In particular, we can include here ribbons on the base of amorphous and nanocrystalline alloys (AMAG series) with a width of 1 to 30 mm and a thickness of 15 to 30 μm, toroidal cores, as well as stock-produced electromagnetic components. All the goods produced by the company have the required certificates and correspond all modern European and North Amercian standards.

Toroidal amorphous and nanocrystalline cores

mstator
When designing inductors using cores based on amorphous and nanocrystalline alloys one can mention following advantages: :
  • Reduced weight
  • Reduced copper loss due to turns number decreasing
  • Extended temperature range from -60 to 125°С
  • Increased stability of properties and durability
  • High accuracy for measuring devices
  • Increased efficiency of the finished device

In addition, the magnetic cores produced by Mstator have a high initial magnetic permeability, high values of induction (up to 1.5 T), smaller dimensions in comparison with products on the base of traditionally used materials.

Amorphous cores with high permeability

Toroidal MSF coresare made of thin (25 microns) amorphous ribbon (AMAG-170) on a base of cobalt with a flat hysteresis loop and are characterized by high magnetic permeability and low losses. Such cores have a typical magnetic permeability of 120,000 or more. Inductors of common-mode filters based on MSF series cores require a smaller number of turns of winding, that ensures a small parasitic capacitance. In addition, cores are characterized by smaller dimensions and higher insertion attenuation in a wide range of frequencies in comparance with products based on ferrites and permalloys.

The design involves an installation of a tape wound core into a ragged protective container made of polyamide-reinforced glass and its fixation with silicone sealant. The container has rounded edges and is designed for direct application of the winding with a thick wire. The container provides a reliable mechanical protection of amorphous material and preservation of its properties. All materials comply with UL94V-1/0.

Application: common-mode filter chokes, transformers in data transmission systems, high-precision current transformers including for electronic electricity meters, sensors for RCD (Protective Disconnect Device)..

Nanocrystalline MSFN cores with high permeability for common mode chokes

New series of toroidal MSFN-T, MSFN-TH cores are being produced from thin (20 ÷ 25 µ) nanocrystal ribbons Fe( AMAG-200C)and are characterised by high values of saturation flux density (1,2 T) and magnetic permeability (up to 80 000) in a wide frequency band, low losses, and a higher working temperatures (up to 120°C), perfect thermal stability. Series MSFN-TH is the result of last investigations. These items have higher permeability values. Also MSFN cores are manufactured in two designs – in a plastic container (MSFN-TH) and with a coating in a form of epoxy powder paint (MSFNP-TH). These cores have typical permeability values 90 000 and more. Common-mode filter chokes on the base of MSFN cores require a smaller number of turns of the windings, which provides a small parasitic capacitance, have smaller dimensions and provide a higher insertion loss in a wide frequency range in comparison with traditional products based on ferrites and permalloys.

Application: common-mode filter chokes, transformers in data transmission systems, high-precision current transformers including for electronic electricity eters, sensors for RCD (Protective Disconnect Device), telecommunications.

Amorphous cores for high frequency transformers

MST cores are made of amorphous alloy AMAG-186 (A,B,C) with permeability values of 3300, 2200, 1400 respectively. The induction value is 0.9 ... 1.0 Т. More over, distinctive characteristics are linear flat hysteresis loop with relatively low magnetic permeability . Typical permeability slightly depends on working amplitude of induction and frequency. The material has a negative dependence of loss on temperature. It is recommended to apply in: current transformers with DC bias, high-frequency current transformers, AC/DC power transformers and DC/DC converters, etc.

Magnetic cores with a distributed gap

Toroidal MSC cores are made of thin (25 µm) amorphous ribbon on the base of ferrum (AMAG-202). A distributed gap obtained due to the special regime of a thermomagnetic treatment helps to reduce losses, to provide low cost and small chokes sizes with respect to the same products with an air gap. High values of saturation magnetic induction, low losses and a higher level DC bias up to 35 E,( when sustaining a high permeability) set apart the MSC cores from products made from traditional materials used for output chokes, PFC chokes, smoothing chokes, flyback transformers and so on.

3) The limiting value of the magnetomotive force, defined as the product of the DC bias current and the number of turns of the winding, in which the inductance coefficient A L is at least 60% of the initial value.

Cores with non-magnetic gap

MSC-NG cores are made of thin (25 microns) Fe-based amorphous ribbon. A unique combination of high saturation induction (1.5 T) and low losses makes them indispensable for all applications associated with the storage of energy. High saturation induction, low loss and very high DC bias while maintaining high permeability distinguish MSC-G series magnetic cores from products made of traditional materials used for the output chokes, power factor correction chokes, smoothing chokes, flyback transformers, and so on.

Design:Ribbon wound magnetic core impregnated with a special compound and having fixed non-magnetic gap with a textolite filling is placed into a hard protective container of glass-polyamide and mechanically fixed with silicone sealant. The container provides reliable mechanical protection and preservation of amorphous material's properties. All materials comply with UL94V-1 / 0.

1)Outer diameter - inner diameter - height.
2) At F=100 KHz, Urms=1 V; T= 25°C.
3)The limiting value of the magnetomotive force, defined as the product of the DC bias current and the number of turns of the winding, in which the inductance coefficient A L is at least 60% of the initial value.

Noise suppression bead cores for single-turn chokes

MSB cores are being produced of thin amorphous Co-doped ribbon. They have a rectangular hysteresis loop and a significantly higher magnetic permeability compared with magnetic cores based on Fe-Ni permalloy alloys. Structurally, the products are optimized for using with a single-turn winding. This winding usually appears to be the output of a component (transistor, diode).This class of products provides a higher effective interference suppression , essentially eliminating the cause of their occurrence, significantly reduces losses compared to classic RC dampers and ferrite cores for a similar purpose. The distinctive characteristics include: squareness ratio up to 0.85, high permeability, cylindrical shape, miniature dimensions. Such products can be worn directly on the component leads.

Fields of application: suppression of short spikes and HF oscillations on the fronts due to a changing in the nature of the of active components switching, the elimination of the cause (source) of interference. Products are used in switching power supplies, motor control circuits, switching semiconductor devices, etc..
