SI9400122A - Electrical measurement system with eccentric multi sides coil in magnetic field - Google Patents

Abstract

Thanks to the proper polarity and location of the magnets, this bipolar electric measuring system - with a moving coil (5) mounted eccentrically in relation to the rotating axis (7) - has two contrary-oriented magnetic fields (B) in its air slots (6), which results in forces acting/imparting on several sides of the moving coil (5); according to the laws of physics the forces (F) in the magnetic field (B) act in the same direction and the electric moment they cause is stronger. The measuring system can therefore be more robust, and its production cheaper.

Description

1. OPIS IZUMA1. DESCRIPTION OF THE INVENTION

Izum je analogni električni merilni sistem z vrtljivo tuljavico (5), skozi katero teče enosmerni tok (I) in je nameščena ekscentrično glede na os vrtenja (7). Magnetno polje (3), ki je v zračnih režah (6) nasprotno orientirano, povzroča po fizikalnem zakonu delovanje sil (F) na več stranic vrtljive tuljavice (5) v isto smer. Vrtljiva tuljavica (5) ima dve, oziroma tri stranice v magnetnem polju (B) zračne reže (6).The invention is an analog electrical measuring system with a rotating coil (5) through which a direct current (I) flows and is positioned eccentrically with respect to the axis of rotation (7). The magnetic field (3), which is in the opposite direction in the air slots (6), causes the force of law (F) to act on several sides of the rotating coil (5) in the same direction. The rotating coil (5) has two or three sides in the magnetic field (B) of the air gap (6).

Rešitve enopolnih merilnih sistemov z ekscentrično nameščeno vrtljivo tuljavico glede na os vrtenja, ki imajo eno stranico vrtljive tuljavice v magnetnem polju zračne reže, so znane.The solutions of single-pole measuring systems with an eccentrically mounted rotating coil relative to the axis of rotation having one side of the rotating coil in the magnetic field of the air gap are known.

Znane pa niso rešitve dvopolnih električnih merilnih sistemov z ekscentrično nameščeno vrtljivo tuljavico (5) glede na os vrtenja (7), ki ima zaradi ustrezne polaritete in ustrezne namestitve magnetov, povzročena nasprotno orientirana magnetna polja (B) v < 1 zračnih režah (6). Ta.usmeritev povzroča večjo efektivno dolžino vrtljive tuljavice (5) v magnetnem polju (B), na katero delujejo po fizikalnem zakonu: Vodnik v magnetnem polju... , sile (F) na več stranic vrtljive tuljavice (5) v isto smer in je povzročen močnejši električni vrtilni moment. Merilni sistem je zato robustnejši in proizvodnja je cenejša. Grajen je lahko iz feritnih mehkomagnetnih materialov in feritnih magnetov.However, there are no known solutions for two-pole electrical measuring systems with an eccentrically mounted rotating coil (5) with respect to the axis of rotation (7), which, due to the proper polarity and proper placement of the magnets, results in counter-oriented magnetic fields (B) in <1 air slots (6) . This direction causes the greater effective length of the rotating coil (5) in the magnetic field (B) to which they operate according to the physical law: A conductor in the magnetic field ..., forces (F) on several sides of the rotating coil (5) in the same direction, and a stronger electrical torque is caused. The measuring system is therefore more robust and production is cheaper. It can be made of ferrite soft magnetic materials and ferrite magnets.

Ustrezno usmeritev magnetnega polja (B) se doseže s tem:The proper orientation of the magnetic field (B) is achieved by:

- da sta dva trajna magneta (1),(2) v obliki kolobarja na sl.l in sl. 2- that there are two permanent magnets (1), (2) in the form of a ring in FIG. 2

- ali dva trajna magneta (3),(4) v obliki kvadra na sl.3,- or two permanent magnets (3), (4) in the form of a square in Figure 3,

- kakor tudi štirje magneti (8),(9),(10),(11) v obliki kvadra na sl .4,- as well as four magnets (8), (9), (10), (11) in the form of a square in Fig. 4,

- oziroma dva trajna magneta (12),(13) v obliki radialno ukrivljene ploščice na sl.5,- or two permanent magnets (12), (13) in the form of a radially curved plate in FIG. 5,

- kakor tudi štirje trajni magneti (14),(15),(16),(17) v obliki radialno ukrivljene ploščice na sl.6, pozicionirani tako, da tvorijo nasprotno (3N-NS) ali (NS-SN) orientirana magnetna polja (B) v zračnih režah (6).- as well as four permanent magnets (14), (15), (16), (17) in the form of a radially curved plate in Fig. 6, positioned to form an opposite (3N-NS) or (NS-SN) oriented magnetic fields (B) in the air slots (6).
