" [Prior Art] The stator punching and winding form of a three-phase wire-start permanent magnet synchronous crane is basically the same as that of a two-phase induction motor, but the rotor structure is more complicated. At present, the rotor magnetic pole structure of the induction permanent magnet synchronous motor can be roughly divided into three types according to the magnetic circuit of the magnetic pole: radial type (as in the first figure) and tangential type (such as the second figure). Show) and hybrid (such as the three structures shown in the third figure, the rotor magnetic pole is made of high-performance rare earth non-ferrous boron (NdFeB), and the first sis Chu-return nm _. In terms of structure, when the motor performs the induction starting surface, it enters the circuit of the rotor core (ie, the rotor back iron) and ΐ 7; the _ rotor magnetic pole junction: the eight magnetic leakage is large, and for the rotating shaft The magnetic isolation ring must be used to consider the shortcomings of the =-type and tangential-type hybrid structures. Therefore, the application of the structure of the Wei-hei hybrid structure is more complicated than the previous enchantment and tangential type, but the structure is too complicated to be its disadvantage. And ifΓΐ 'The creator of this case is actively engaged in research and innovation, and finally has the innovation and can be used for the creation of the industry. [New content] The purpose of the broadcast ft is to provide a permanent magnet synchronous motor with induction start~ Rotor pole structure, these pole structures To make M323161 consist of a whole magnet, the working time of segment assembly can be reduced, and the magnetic flux distribution generated by the curved magnetic pole is more uniform and smooth. The magnetic synchronous motor mainly comprises a tweezers and a rotor magnetic pole structure 'the towel thereof, and the rotor magnetic pole structure has a plurality of magnetic poles and a rotor ferromagnetic pole integral magnet, and the squirrel-cage conductor is slotted on the rotor core. Means] In order to make the purpose, characteristics and efficacy of the creation, further understanding and (10) the same as the specific embodiment to be exemplified and illustrated with the following description. The preferred embodiment mainly comprises a stator and a rotor pole structure. The punching piece and the winding and group forming form of the stator are the same as the two-phase wire motor, and will not be described in detail; please refer to the fourth magnetic pole structure having a plurality of magnetic pole structures. Magnetic pole (1)) and rotor iron. (12) Magnetic pole (11) is a circular arc magnet made of a South rare earth permanent magnet material - NdFeB. Adjacent magnetic poles (1)) are alternately arranged in the radial direction of the inner core of the rotor core (10) in the order of N poles and S poles, so that the adjacent magnetic poles (11) are formed in a different pole shape, and the rotor core (10) is slotted. The device is a squirrel cage conductor (10), between the rotor pole (11) and the squirrel cage conductor (13), and a core of appropriate size is left as a magnetic bridge ((4). For the sake of simplicity, the permanent magnet in the rotor core is firstly used. The magnetic pole is removed, and the permanent magnet synchronous motor of the induction start becomes a three-phase induction wire machine with asymmetrical magnetic circuit of the rotor due to the position of the rotor magnetic pole (4). When the stator winding is connected to the three-phase symmetrical AC power supply with the frequency f At the time of the air gap, M323161 is produced, and if it is s, the AC current of the body frequency is sf. Because of the mismatch of the rotor magnetic circuit, L#Xq, the magnetic field generated by the rotor current It is possible to divide the rotating magnetic field with respect to the rotational speed of the rotor, the two squid wires 7 τ Sns^ n2r=~sns ^ the rotating magnetic field in the positive direction of the rotor with respect to the rotational speed of the stator (4) S, and the two-dimensional rotating magnetic field relative to the stator The speed is mr+nr=(l -2s)ns 〇

When the permanent magnet of the rotor iron seal is plugged with permanent magnets, the magnetic field generated by the permanent magnet pole of the rotor is the secret of nnn=G_s)ns. A current Ig having a frequency of (ls)f is induced in the stator winding to form a transmitting machine that is directly sub-connected with the three-phase power source, and generates a lateral dynamic torque Tg to the rotor. Therefore, the total average torque L during the starting of the permanent magnet synchronous motor is composed of three torque components of Ta, 1\> and Tg, that is, Tav = Ta + Tb + Tg. M323161 This creation uses high-performance rare earth permanent magnet material ~ NdFeB, which reduces the rotor loss and stator excitation current, while the efficiency f power factor is silently improved, and this creation does not control H and position. Sensing ^ can be directly connected to the three-phase power supply in any position of the rotor. The torque is generated by the current of the rat-type guide. The shape should be started. After the rotor reaches the synchronous speed, it becomes a permanent magnet synchronous motor. , because the running speed of this creation is synchronous speed, the motor (slip rate is about 3~5%) is high, so it is better to drive the load like fan or fruit, the overall system efficiency is better than the use of general three-phase induction The electric motor = the mover is further improved; it is worth mentioning that the design of the magnetic pole is formed by the arc of the long-term magnet, so that the distribution of the magnetic lines is more comprehensive, and the creation is made up of innovation. It can indeed meet the intended purpose 'and the original rhyme is tested and tested to verify its merit = good' and has superior industrial utilization and new reliance.
