Title: ELECTROMAGNET HAVING MULTI-CORE STRUCTURE
Abstract:
The present invention relates to an apparatus for preventing blockage of a slurry pump formed such that a concentration of solid particles does not exceed a threshold value so as to prevent the occurrence of blockage in a slurry pump, and an electromagnet for generating a magnetic field by winding a coil around a core comprising: a support for supporting the electromagnet; a plurality of winding cores formed by winding coils around cores, and comprising at least three winding cores having magnetic poles when a voltage is applied to the coils through an electrode terminal for supplying the power to the electromagnet; a pair of magnetic flux hubs formed to be supported by the support and to symmetrically face each other, mechanically coupling the plurality of winding cores, and concentrating the magnetic field to be generated from the plurality of winding cores; and a pair of magnetic pole cores having polarity caused by the magnetic field concentrated by the pair of magnetic flux hubs, and supported so as to symmetrically face each other in a state in which the cores are coupled to the magnetic flux hubs, and thus the electromagnet reduces an electrical and magnetic resistance, and has high efficiency on the basis of a Halbach array so as to reduce power consumption.
