Abstract
The invention relates to a stator iron core of motor which has several couples of rectangle holes on the parts that tightly close to the container wall while the arrangement of rectangle holes is the same with the direction of magnetic circuit of stator and said rectangle holes extend along the axis of stator iron core. The inventive stator iron core with rectangle holes can solve the worse heat emission of present stator of motor while it can improve the heat emission effect and improve the operation efficiency of motor.
Description
Technical field
The present invention relates to the motor of compressor, particularly relate to the stator core of compressor electric motor.
Background technology
Motor is the power source of compressor, and it converts electric energy to mechanical energy, drives compressor piston work, realizes the compression to refrigerant vapour.Therefore, the effect of motor in compressor is very important, and motor properties also is directly connected to the performance and the product quality of whole compressor.
Generally speaking, the motor of compressor is by stator cylindraceous and place the cylindrical rotor of stator to form.Stator is made of iron core and the enamelled wire winding that silicon steel sheet is laminated into, and uniform axial notch on its inner cylinder face embeds winding in the axial notch.Rotor is made of iron core and the conductor that is arranged in intimate.The stator of energized forms alternating magnetic field, produces faradic rotor conductor and produces torque and make rotor rotation under the effect of variation magnetic field, and rotor is directly installed in the rotating shaft of compressor, drives the piston motion of rotating shaft and then drive compressor by it.
The motor internal that runs up constantly produces heat, and motor temperature is raise.Motor temperature is higher, and its operational efficiency can reduce.Therefore, the electric machine structure that helps dispelling the heat can improve the operational efficiency of motor.
But prior motor is installed in the closed container of compressor, and motor stator is close to chamber wall, can't dispel the heat in the position of being close to chamber wall at motor stator core.That is to say that in the prior art, there is the bad problem of motor radiating that makes in the stator core construction of motor.
Summary of the invention
The present invention is directed to the bad problem of heat radiation that existing motor stator exists, improve the stator structure of motor, slot is opened at the position that is close to chamber wall at motor stator core, to make things convenient for the heat radiation of motor.
The stator core of motor involved in the present invention is opened slot in its many places, position that are close to chamber wall, and every place has a pair of slot, and the arrangement of slot is consistent with the stator magnetic circuit direction, and the hole depth of slot extends axially along stator core.The stator core that has slot has been promoted radiation effect of motor, has improved the operational efficiency of motor.
