Abstract
The utility model relates to a DC motor. Electric brushes and reversers used in the prior art have the defects of complicated structure and frequent failure. A stator of the utility model adopts an n-shaped silicon steel sheet iron core coil with an inward opening, the coil is wound on both ends of the stator, inner wheels of both ends of a motor shaft are provided with bar-shaped silicon steel sheets which are parallel to the shaft, two sets of circular silicon steel sheets corresponding to the magnetic poles of the stator are sheathed on the periphery of the bar-shaped silicon steel sheets, each contactor is composed of a cylindrical coaxial conductor and a circular pipe-shaped coaxial conductor, an inner contactor is arranged on the motor shaft, and an outer contactor is arranged on a cover of a motor casing. Because the contactors are used for replacing an electric brush and a reverser, the utility model has the advantages of simple structure and convenient maintenance.
Description
The utility model relates to a kind of DC motor.
Existing DC motor, because its armature uses brush and commutator, structure is complicated, and use, inconvenient maintenance are to be out of order easily by it, and useful life is short; Starting needs auxiliary equipment, troublesome poeration not only, and also cost is higher.
The utility model purpose has proposed a kind of with the novel direct-current motor of contactor for charged brush and commutator at the deficiencies in the prior art.
Task of the present utility model is to realize like this, the utility model is a kind of casing that comprises, stator, the DC motor of rotor, stator is to adopt " ∩ " shape silicon sheet core magnet exciting coil, its opening magnetic pole is inwardly facing to rotor, back and motor shaft secured in parallel are on casing, every group of coil is around in two ends, two connects the terminal box power supply, the bar shaped silicon steel sheet parallel with axle is housed on the wheel external tooth in motor shaft two, interior wheel is gone up the center insulation heart with holes is housed between every group of bar shaped silicon steel sheet, two groups of inside and outside toothed ring-shaped silicon steel sheets are stuck in the periphery of bar shaped silicon steel sheet from two headgears of motor shaft corresponding to the magnetic pole of stator, the width of every group of silicon steel sheet is identical with a magnetic pole of stator core, the aperture of every group rotor coil by the heart in the heart of insulating is on the external tooth of ring-shaped silicon steel sheet, between two groups of annular cores, each coil winding-direction in correspondence with each other is opposite, rotor coil the two poles of the earth are connected on respectively on the inner core and outer core of interior contactor, contactor is to be made of cylindrical and two coaxial conductors of tubular, interior contactor is to be contained on the axle of motor, change together with rotor, external tentaculum is contained on the casing cover of motor, and withstand with spring at the rear portion.Adorn the plate of a trough of belt on motor reel, have two ends that the slide block of spring is housed in the groove, adorn a slidingtype variable resistor on the plate, series connection is between interior contactor and working rotor coil, and the sliding end of its resistance slides with slide block.Interior wheel on the motor reel, its spoke is an impeller blade.
The utility model compared with prior art owing to taked with the contactor band for brush and commutator, institute is so that electric motor structure is simple, maintenance is simple to operate easily, thereby cost also the end in existing DC motor; And do not need any auxiliary equipment when starting; When utilizing rotating speed fast again, the centrifugal force of slide block is adjusted a variable resistor, thereby has controlled input power, so tangible power savings is arranged again; And the spoke of wheel is a vane type in the cast iron of motor, can incite the wind heat radiation again voluntarily.
