Abstract
The present invention provides a direct current permanent magnetic synchronous motor. The silicon steel sheet of the stator core is formed by overlapping rectangles which are respectively cut with a circular arc at the same side of two ends of the rectangle. The stator core (2) is obtained by installing two straight-line iron cores which are overlapped by two silicon steel punched pieces with the mode that the surfaces with arc are parallel relatively. Two straight flanges of two windings (5) installed on the stator iron are respectively straight flanges which is provided at the middle part of two straight-line iron cores. A rotor (3) is respectively installed at the positions which are between two straight-lien iron cores and between the magnetic poles at two ends, and two rotors are installed totally. Compared with prior art at aspect of material, the motor of the invention is not provided with crushed aggregates at the U-shaped opening in material blanking. The dimension of the winding is reduced, and the length of the varnished wire at the state of same winding number is shortened thereby saving the material. At aspects of installing and wire connecting, the effect when one piece is installed is homologous to the effect when two pieces are installed, and the wire connecting is the same. Additionally, two integrated motors are better than two separated electric motors in visual effect.

Summary of the invention
At above-mentioned deficiency, problem to be solved by this invention is how a plurality of axles to be integrated in the motor, thereby a kind of acquisition cost and convenient DC permanent magnetism synchronous machine of installing saved is provided.
DC permanent magnetism synchronous machine provided by the invention, stator core is arranged, two straight flanges being used for installing winding and the circular arc wall in opposite directions of magnetic poles are arranged on the stator core, there are two windings to be installed in respectively on two straight flanges of stator core and constitute stator, have p-m rotor to be installed in the space that circular arc wall constitutes in the stator core;
Wherein
The shape of forming the silicon steel punching of stator core is that the two ends on same long limit on a rectangle respectively cut out a circular arc, and has the startup breach on the circular arc at one end;
Stator core is that two fonts are arranged, and obtains with the parallel in opposite directions installation of the one side that circular arc is arranged with the folded mutually straight line iron core of forming of said silicon steel punching by two;
Two straight flanges that two windings are installed on the stator core are the straight flanges that are in two straight line iron core stage casings respectively;
Constituting the circular arc wall in opposite directions that rotor space is installed on the stator core is the circular arc wall that is in two the same end of straight line iron core inboards respectively;
Respectively there is a space that rotor is installed at two ends between two straight line iron cores;
In two end spaceses between two straight line iron cores a rotor is installed respectively, two rotors are installed altogether.
DC permanent magnetism synchronous machine provided by the invention, with two parallel placements of straight line iron core, respectively there is a pair of face in opposite directions at their two ends, after two windings of DC permanent magnetism synchronous machine are installed in these two straight line iron core stage casings respectively, this two couple face in opposite directions is exactly two pairs of magnetic poles, thereby can drive two rotors.Compared with prior art, the present invention is from material, the straight line iron core is equivalent to the stretching of U-iron core, then the particle of U-shaped opening part has not just existed when blanking, because two windings are enclosed within respectively on two straight line iron cores, the length of winding enlarges then reduced, and the length of enamelled wire is dwindled under the situation of the same number of turn, and generally the DC permanent magnetism synchronous machine of this two disjunctors will be economized than two materials that DC permanent magnetism synchronous machine consumed of Dan Li under same power condition.In installation and wiring, just be equivalent to install two as long as install one, wiring is too.Good from two motors of visual effect one also two motors in addition than discrete.
DC permanent magnetism synchronous machine provided by the invention, said stator is respectively installed resulting two the half of stators of winding with two straight line iron cores and is obtained by center symmetry installation, make with convenient, promptly can unify to make half of stator core, winding and instrument, be convenient to install.
DC permanent magnetism synchronous machine provided by the invention connects with the insulation positioner between said two straight line iron cores, to determine distance between the two so that be installed to motor self housing or use in the housing of device of motor.
