Abstract
The utility model relates to a disc-like permanent magnet synchronous motor which belongs to the improvement of a motor. A disc-like stator and a disc rotor are arranged in pairs, and the disc-like permanent magnet synchronous motor is formed. A plurality of slots which are cut on the stator core are circumferentially and uniformly distributed. The lines of the stator windings arranged in the slots are released in a single layer concentric way. The disc rotor is fixed on a motor shaft, comprises a red copper starting wheel into which permanent magnets are symmetrically embedded according to the polarities. The disc-like permanent magnet synchronous motor has the advantages of short axial dimension, low cost, high efficiency, simple structure, stable operation, and easy use, being particularly suitable for a sealed pump integrated with a pump.
Description
The utility model relates to a kind of disc type permasyn motor, belongs to the improvement of motor, is particularly suitable for making the sealing electric pump of electromechanical, also can be used on the little recorder of axial space, the photocopier.
In the past in petrochemical system, in order to prevent the generation of problem such as run, drip, leak, and adopt canned pump or separate pump, although satisfied production requirement, but also come with some shortcomings,, must rotor and divided stator be severed with stainless steel sleeve as canned pump, strengthened air gap, thereby when the stator rotating magnetic field is skimmed over housing,, loss is increased owing to produce eddy current therein, obviously reduce power factor, the energy index of asynchronous motor, cause the efficient of canned pump lower; And for example separate pump is made up of asynchronous motor, magnetic coupler, process pump and stainless steel cage, thereby visible structure complexity, volume are greatly, occupation of land is many, cost is high, and efficient is very low simultaneously, and operation is stable inadequately, for these reasons, it being applied is limited to.
The purpose of this utility model be to provide a kind of simple in structure, axial dimension is short, cost is low, efficient is high, stable, the desk permanent-magnet motor of saving special steel material and permanent magnetic material.
The purpose of this utility model realizes by the following technical solutions, be to form by a relative device of disc type stator with disc rotor, the groove of opening in the stator core on the described disc type stator is uniformly distributed along the circumference, and the stator winding in the groove rolls off the production line by the individual layer concentric type, is loaded in the shell; Described disc rotor and motor shaft are solidly installed, and are made up of starter cup and yoke that copper plate is made, and being uniformly distributed along the circumference on the starter cup is inlaid with several permanent magnets, and it is by polarity the two poles of the earth symmetric arrangement.
Described permanent magnets is 20, and every effective area is 11.5cm
2, its main magnetic flux φ is 78 * 10
-4Wb.
The notch of described stator seals with magnetic material.
The utility model compared with prior art, because the structural measure that has adopted disc type stator and rotor that dress is formed, and through model machine actual measurement proof have simple in structure, volume is little, axial dimension is short, cost is low, efficient is high, its rotating speed is not subjected to that change in voltage influences, advantage such as stable, implement to be beneficial to and to apply easily.
Fig. 1 is the plan structure schematic diagram that the utility model and pump are made one.
Fig. 2 is the main TV structure schematic diagram that the utility model and pump are made one.
Fig. 3 is the utility model main flux path schematic diagram.
Embodiment of the present utility model is described in conjunction with the accompanying drawings, be that what to make one with 3KW and pump 9 is example, the groove of opening in the stator core 1 in the disc type stator casing is uniformly distributed along the circumference, stator winding 2 in the groove rolls off the production line by the individual layer concentric type, 35 of every grooves, line directly is 1.2mm, is provided with insulating pad 8 between iron core 1 and the stator winding 2, and its notch seals with magnetic material 3; Disc rotor is relative with the disc type stator to be installed, the shell of stator casing and pump 9 matches, rotor disk is made up of red copper or aluminium starter cup of making 4 and the yoke 6 that is loaded under it, rotor disk and motor shaft are solidly installed and are coaxial with pump 9, being uniformly distributed along the circumference on the described starter cup 4 is inlaid with 20 permanent magnets 5 by polarity the two poles of the earth symmetric arrangement, and its effective area of every is 11.5cm
2, main magnetic flux φ is 78 * 10
-4Wb.
After stator winding 2 energized, on stator, produce rotating magnetic field, under the effect of stator rotating magnetic field, this moment mouse cage in suitable asynchronous electric starter cup 4 in induced potential and electric current, thereby the generation torque drives rotor and rotates along stator rotating magnetic field direction, when rotating speed near with leg speed the time, the permanent magnetic field that relies on rotor and the interaction of stator rotating magnetic field are with the rotor operation of pulling in, and the synchronous speed n and the supply frequency f of its motor have following relational expression:
n＝ (60f)/(P)
In the formula: the P-number of pole-pairs
When P one timing, n and f are proportional relation thereby as seen.
