Sub- iron core.
Further, when yoke portion ring is that multi-section circular arc combines, the number of segment of circular arc is no more than stator core teeth portion quantity
Twice.In practice, the number of segment of circular arc needs to increase and decrease according to the actual situation.
Further, single or multiple yoke portions ring can be set in the same side of the stator core.It is compound under regular situation
The single yoke portion ring (the referred to as compound stator core of monocyclic) that stator core the same side uses.It according to actual needs, can be fixed
Multiple yoke portions ring (the referred to as compound stator core of polycycle) is set on sub- iron core the same side.
Further, when ring setting in yoke portion is multiple, the number of rings of yoke portion ring is no more than yoke portion width in millimeters
Value.
Further, when ring setting in yoke portion is multiple, there can be air gap between yoke portion ring, be not necessarily intended to fit closely.
Further, when ring setting in yoke portion is multiple, there can be difference in height between yoke portion ring, width can also be different.
Further, the width of yoke portion ring is no more than the yoke portion width of stator core stamping sheet.In practice, the width of yoke portion ring
Degree needs to increase and decrease according to actual demand, can be of different sizes with the width in stator core stamping sheet yoke portion.
Further, the height of yoke portion ring is no more than the height of stator core.In practice, the height needs of yoke portion ring are pressed
Increase and decrease according to actual demand, it can be different from the height size of stator core stamping sheet.
Further, the outer contoured shape of yoke portion ring is circle or other shapes.The yoke portion of different composite stator core
The outer contoured shape of ring can be different, and the outer contoured shape of each yoke portion ring of the compound stator core of polycycle can not also
Together.
The utility model also provides a kind of motor, and the motor includes above-mentioned compound stator core.
The utility model increases yoke portion ring in the yoke portion of existing stator core, so that the yoke portion of compound stator core is higher than tooth
Portion.In motor operation course, this evenly distributes motor stator magnetic circuit, substantially reduces stator yoke magnetic density, reduces
Motor iron loss.Stator end leakage field can also be reduced simultaneously, so that motor magnetic circuit is utilized effectively.The reduction of motor magnetic density
Motor temperature rise can be also reduced, motor and compressor performance can be improved.In terms of motor process, stator yoke is higher than teeth portion, paint
Envelope curve is embedding on the stator teeth, in production and transportational process, can play a protective role to enameled wire, improve the safety of motor
Energy.
The utility model has the following beneficial effects:
1, the increase of yoke portion ring reduces stator core yoke portion magnetic density, reduces motor iron loss；
2, the increase of yoke portion magnetic density is so that the reduction of stator end magnetic leakage, is effectively utilized motor magnetic circuit；
3, motor temperature rise is reduced, motor and compressor performance can be improved；
