Description
Technical field:
The utility model belongs to technical field of motors, refers in particular to a kind of hinge type stator core.
Background technology:
Existing motor stator core is that punching is formed by stacking.Punching is an integrated ring type structure.By winding the line on the interior stator core that dielectric is being installed around machine.In around the line mouth of machine pass on stator core groove could around, therefore, the width of groove is greater than the width of line mouth, namely notch will be done wide.And the wide meeting of motor stator notch causes the rotor of magneto to produce great cogging torque when rotating, this not only can cause on client's experience larger impact, as feel, tying point is arranged, torque pulsation is large etc., and has restricted the application of motor at the high accuracy control field.Simultaneously, around the reciprocating motion of process center line mouth the time skeleton can appear beating, the line mouth is easily disconnected, has increased expense, long processing time is incured loss through delay and is produced.In order to solve this phenomenon, people have developed the motor stator core of piecemeal split mounting type.the motor stator core of piecemeal split mounting type is because major part is used flying fork type coil winding machine coiling, its notch is spliced to form by adjacent two stator tooth pieces, do not exist the line mouth to pass the stator rabbet problem, the narrow as far as possible even closed slot that the width of rebate of stator can be done, eliminated above-mentioned problem, but exist: respective outer side edges is not tight yet, easy leakage field, between piece and piece, the splicing magnetic circuit disconnects, iron loss can increase, assembling process is complicated, the welding sequence trouble, and need special-purpose frock to carry out assembly unit, during assembly unit, easily dislocation between piece and piece, the up and down is inconsistent, the end of a thread is more, production efficiency is low, the high defective of motor power consume.
Summary of the invention:
The purpose of this utility model is to provide a kind of wiring technique of saving, and simplifies welding procedure, and notch is narrow, the hinge type stator core that reliability is high.
The utility model is achieved in that
A kind of hinge type stator core, the block that is formed by some punchings stack, described punching includes the annular punching of several fans, connect by intercell connector between adjacent fan annular punching, the annular punching stack of several fans forms iron core unit, intercell connector by stack between iron core unit connects, the head and the tail two ends of the block formation stator core that is connected.
The head and the tail two ends of above-mentioned block are by being welded to connect or the chimeric connection that presses.
Above-mentioned fan annular punching is the I shape punching, and the outer arc section is greater than the arc length of inner arc section, and the outer arc section of iron core unit is formed with the stator slot notch greater than the inner arc section between the inner arc section between adjacent iron core unit.
Above-mentioned stator slot notch is open slot or closed slot.
Follow closely riveting by riveted joint between above-mentioned punching and form block.
Be built up block with the protruding overlapping of groove fit from cramp on groove on the front of above-mentioned punching and reverse side.
Be provided with from top to bottom breach on inner arc section on above-mentioned block on four adjacent iron core unit, adjacent breach coordinates and forms three Hall installation positions in twos.
The advantage that the utility model is given prominence to compared to existing technology is:
1, be connected by intercell connector between iron core unit of the present utility model and iron core unit, notch is very large when coiling, coiling is convenient, and each coil of phase uses single line around getting final product, the end of a thread is few, has saved wiring technique, winds after line as long as the initial and tail sections of block is divided to weld, simplify welding procedure, improved reliability;
2, the utility model assembly unit is simple, and block is crooked, and head and the tail two ends welding is got final product, and production efficiency is high, and energy consumption of electrical machinery is few;
3, dislocation can not appear between iron core unit of the present utility model and iron core unit, and unanimous between the higher and lower levels, connect together between iron core unit and iron core unit, iron loss is few.
4, be formed with the stator slot notch between the inner arc section between the iron core unit that the utility model is adjacent, notch can be designed to very little even closed slot, not limited by wire winding, and cogging torque is little, and torque pulsation is little, good hand touch.
Description of drawings:
Fig. 1 is the schematic diagram of block of the present utility model;
Fig. 2 is block partial schematic diagram of the present utility model;
Fig. 3 is that bending of the present utility model forms the schematic diagram of stator core when does not weld at the head and the tail two ends afterwards.
Embodiment:
The below is further described the utility model with specific embodiment, referring to Fig. 1-3:
a kind of hinge type stator core, the block 10 that is formed by some punchings stack, described punching includes the annular punching 20 of several fans, connect by intercell connector 30 between adjacent fan annular punching 20, intercell connector 30 is one-body molded between the annular punching 20 of fan, annular punching 20 stacks of several fans form iron core unit 40, intercell connector 30 by stack between iron core unit 40 connects, between iron core unit 40 and iron core unit 40 inconsistent phenomenon can not appear, unanimous between the higher and lower levels, the head and the tail two ends 101 of block 10, 102 are welded to connect or the mode such as the chimeric connection that presses forms stator core.
