The concentrated winding is achieved by the nine coiling elements, the starting torque of the motor is improved, a cooling groove is arranged on the outer circumferential surface of the rotor, and a gap is reserved between the stator and the rotor, so that the motor can be cooled simultaneously by the cooling groove and the gap between the stator and the rotor, the stator and the rotor can be efficiently cooled, and the service life of the motor is prolonged; and six pieces of arc-shaped permanent magnetic steel are circularly distributed, and a magnetic field generated by the arc-shaped permanent magnetic steel is in normal distribution, so that the work efficiency of the motor is improved.
Description
Technical field
The invention belongs to technical field of motors, be specifically related to a kind of compression motor for air conditioning for automobiles.
Background technology
What existing air conditioning for automobiles compression motor adopted is a plurality of winding slots, generally more than 50 grooves.When use had the punching of so many winding slots, coil mainly was welded with the single stator slot that passes, complex process, and potential safety hazard is large.And use so many winding slots to cause electric motor starting relatively poor, the magnetic circuit skewness causes electric efficiency low, and temperature rise is very high to the high temperature resistant requirement of motor material.Because the motor feels hot that amount high temperature raises for this kind structure, can cause to the permanent magnet of motor nonvolatil injury, in the life-span of having reduced motor, has very large potential safety hazard.
Summary of the invention
For the relatively poor problem of electric motor starting in the above-mentioned technology, the invention provides a kind of air conditioning for automobiles compression motor, it concentrates winding, has improved the detent torque of motor, the efficient of lifting motor.
Realize that technical scheme of the present invention is as follows:
The air conditioning for automobiles compression motor, comprise electric machine casing, and be arranged at stator, rotor in the electric machine casing, described stator inner peripheral surface is provided with 9 winding bodies that protrude to stator heart direction, winding body is provided with outstanding limiting section away from an end of stator inner peripheral surface, above-mentioned 9 winding bodies are arranged in the stator uniformly, form the winding slot that width reduces gradually between the adjacent winding body.
At the stator inner peripheral surface 9 winding bodies only are set, winding just can be concentrated like this, has improved the detent torque of motor.
Described stator outer peripheral face axis direction offers cooling bath.When the motor compressor internal work, utilize the liquid of compressor inside to lower the temperature to motor by cooling bath like this, the temperature of motor is reduced, create the suitable operational environment of temperature to motor, prolong the useful life of motor.
Described stator outer peripheral face axis direction offers for the stopper slot that it is limited in the electric machine casing.Be fixedly installed the installation projection at electric machine casing, so when mounted, stopper slot aimed at the installation projection insert, stator is limited in the electric machine casing.
Described rotor comprises rotor block, and the permanent-magnet steel that is fixedly installed on 6 arcs on the rotor block, and described 6 blocks of arc permanent-magnet steels are arranged rounded.Adopt the permanent-magnet steel of 6 arcs, the magnetic field of generation is normal distribution, improves the efficient of motor.
Described permanent-magnet steel is rubidium iron boron magnet steel.
Adopt above-mentioned scheme, adopted 9 winding bodies to concentrate the mode of winding, improved the detent torque of motor; Offer cooling bath at the rotor outer peripheral face, and has the slit between stator and the rotor, can cool off motor by the slit between cooling bath and stator and the rotor simultaneously like this, thereby high efficiency rotor, stator be cooled, also just prolong the useful life of motor; And adopt the permanent-magnet steel arrangement of 6 arcs rounded, and make the magnetic field of its generation be normal distribution, improved the operating efficiency of motor.
Description of drawings
Fig. 1 is structural representation of the present invention;
In the accompanying drawing, 1 is stator, and 2 is rotor, and 3 is winding body, and 4 is limiting section, and 5 is winding slot, and 6 is cooling bath, and 7 is stopper slot, and 8 is rotor block, and 9 is permanent-magnet steel.
Embodiment
The present invention is further described below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, the air conditioning for automobiles compression motor, comprise the electric machine casing (not shown), and be arranged at stator 1, rotor 2 in the electric machine casing, the stator inner peripheral surface is provided with 9 winding bodies 3 that protrude to stator heart direction, winding body is provided with outstanding limiting section 4 away from an end of stator inner peripheral surface, and limiting section carries out spacing to coiling, prevent from winding the line loosening and come off from winding body; Above-mentioned 9 winding bodies are arranged in the stator uniformly, form the winding slot 5 that width reduces gradually, winding slot shape such as taper in the present embodiment between the adjacent winding body; Offer 3 cooling baths 6 at stator outer peripheral face axis direction.On the outer peripheral face respectively at stator, the quantity of cooling bath can also arrange as required certainly uniformly for 3 cooling baths;
For the ease of stator is limited in the electric machine casing, just offer for the stopper slot 7 that it is limited in the electric machine casing at stator outer peripheral face axis direction, installation projection (not shown) in this stopper slot and the electric machine casing cooperates, projection namely is installed is inserted in the stopper slot, carry out spacing to stator.
Wherein, rotor comprises rotor block 8, and 9, the 6 blocks of arc permanent-magnet steels of permanent-magnet steel that are fixedly installed on 6 arcs on the rotor block arrange roundedly, and the magnetic field of generation is normal state like this, can improve the efficient of motor.In implementation, permanent-magnet steel is rubidium iron boron magnet steel.Selecting 6 blocks of arc permanent-magnet steels is the preferred embodiments of the present invention, can certainly adopt more or less arc permanent-magnet steel to arrange rounded.
