Description
Technical field
The utility model relates to a kind of fragment iron cores of salient pole formula single-phase asynchronous electromotor stator, belong to motor manufacturing technology
Field.
Background technique
The stator core of salient pole formula monopole asynchronous motor, to guarantee that its yoke portion magnetic density is uniform, it is desirable that yoke portion sectional area
It is along the circumferential direction impartial, therefore cambered surface is generally on the inside of yoke portion, the cambered surface and teeth portion medial surface form pointed shape coiling slot cross-section,
Wire winding is difficult thereon, and coiling the number of turns is less, and coiling copper factor is low, and the power density of motor is smaller, and Wen Shenggao, efficiency are low；
Again because accommodating enough coil turns, and reduce the width of teeth portion, causes teeth portion magnetic density excessively high, it is easily supersaturated, make
Motor efficiency is low.
Utility model content
The utility model technical problem of being solved is to provide that inserting between a kind of fragment iron core is close, and yoke portion and teeth portion are hung down
Directly, coil winding the number of turns is more, and coiling copper factor is high, and the power density of motor is big, the high salient pole formula monopole asynchronous motor of efficiency
The fragment iron core of stator.
The utility model adopts the following technical solution:
Fragment iron core described in the utility model is in I-shaped, including yoke portion, pole shoe and is fixedly connected on yoke portion and pole
Teeth portion between boots；The soffit plane in the yoke portion is vertical with teeth portion.
Groove is arranged in yoke portion described in the utility model one end in the width direction, and in yoke portion, the other end is arranged convex in the width direction
Rib, the groove and fin are semicircle；The centerline of the groove of fragment iron core and fin is on the same circumference.
The utility model good effect is as follows: by the identical the utility model fragment iron core of 8 structures along the circumferential direction phase
Columnar stator core is constituted after grafting, the groove of two adjacent phase stator cores is closely inserted with fin, 8 fragment iron
The center of the groove of core and fin on the same circumference, has a self-locking function, and set is attached to after the drive end bearing bracket of motor and drive end bearing bracket mistake
It is full of cooperation, eliminates the gap between piece and piece, magnetic conduction property is reliable；Yoke portion bottom surface is plane, vertical with teeth portion, makes winding
The number of turns of coil winding is more, and coiling copper factor is high, and the power density of motor is big, and the efficiency of motor is greatly improved.
Detailed description of the invention
It is attached that FIG. 1 is a schematic structural view of the utility model；
Attached drawing 2 is that the utility model 8 insertings are columnar stator core construction schematic diagram.
Specific embodiment
As shown in attached drawing 1-2, the utility model fragment iron core is in I-shaped comprising yoke portion 11, pole shoe 12 and solid
Dingan County is the teeth portion 13 of rectangle mounted in the cross section between yoke portion 11 and pole shoe 12, and the cross section of the teeth portion is rectangle, pole shoe
12 bottom surfaces are arc；In yoke portion, 11 sectional area guarantees the premise of reasonable teeth portion width by the compensation of electric motor end cap wall thickness and simultaneously
Under, the bottom surface 16 in the yoke portion 11 is arranged to plane, keeps bottom surface 16 vertical with teeth portion 13；Keep the number of turns of winding coil 2 more,
Copper factor is high, and the power density of motor is big, and the efficiency of motor is greatly improved；In described 11 one end of yoke portion along 11 width of yoke portion
Semicircular groove 14 is arranged in direction, and in yoke portion, semicircular fin 15 is arranged along 11 width direction of yoke portion in 11 other end；By 8
Fragment iron core mutually inserts as stator core, the closely inserting of the groove 14 and fin 15 of two adjacent fragment iron cores；Stator core
Each fragment iron core 1 groove 14 and fin 15 center line distribution on the same circumference, have self-locking function, set be attached to motor
Drive end bearing bracket after with drive end bearing bracket be interference fitted, eliminate the gap between piece and piece, magnetic conduction property is reliable.
The utility model good appearance, design are reasonable.
Finally, it is stated that the above is only the preferred embodiment of the utility model only, not to limit this reality
With novel, any modification, equivalent replacement or improvement made within the spirit and principle of the present invention etc. should all include
It is within the protection scope of the utility model.
