New description: [New technical field] This is a modified structure of permanent magnet motor rotor, especially for setting at least a group of W-shaped magnetic poles in the laminated rotor core, which can effectively improve the motor operation. : Rate and mechanical strength, while having a self-starting rotor structure. [Prior Art] I Conventional permanent magnet synchronous motor and electric wrist synchronous electric motor _ operating principle is roughly the same 'different in the rotor of the permanent magnet synchronous motor, is a permanent magnet (permanent magnet) provided by the hybrid storage winding group _ The magnetic effect, the structure of the permanent magnet motor is relatively solved, which reduces the production cost of the manufacturer, and also solves the problem of the excitation current consumption, and the operating efficiency of the motor is further improved. The θ permanent magnet synchronous motor and the electric excitation synchronous motor have the same characteristics, that is, there is no starting torque between the rotor and the stator, and it cannot be self-starting; compared with the asynchronous motor, the rotor surface has a squirrel cage winding Self-starting __, but can not avoid the loss of core loss and excitation loss, so the advent of the permanent-magnet synchronous motor with asynchronous start--in the permanent magnet lang step __子表·杨 asynchronous electric f The squirrel-cage winding, combined with the characteristics of the two, makes the motor have a self-starting function and retains the better mechanical characteristics and operating efficiency of the permanent magnet synchronous motor. However, due to the need for the electronic axis circuit to hide, the county High, it is not easy to promote. 5 M319579 [New content] In view of this, the main purpose of this creation is to provide a permanent magnet type horse-connected rotor = text 5, '° structure' to simplify the rotor structure of the asynchronous start permanent magnet synchronous motor, so that the installation and manufacture It is simple and easy, and at the same time, it has better service characteristics and running performance. In order to achieve the above purpose, the rotor structure of the present invention consists of a rotor core assembled on a rotating shaft, wherein the rotor core has rotor end rings at both ends, at least one starter • the guide rod passes the rotor end ring to the rotor iron The core is fixed; at least a group of w-type hydromagnets are arranged in the rotor core. The adjacent rings of the w-type permanent magnets of different polarities are arranged in the rotor core, and another _ bridge is arranged between the adjacent w-type sub-groups. (4) The type of permanent magnets consists of a pinch-wise and a cut-off contact surface, a parallel-polar-type w-type hybrid structure, permanent magnets and permanent magnets _ leave (10): these permanent magnets are transparent to the rotor iron Between the cores; to achieve a simplified rotor structure, reduce production costs, while the rotor volume is small, to improve the practical application of the motor design range.

First, please refer to Fig. 1 and in conjunction with Fig. 2, the motor rotor structure cake of the present invention is disclosed. The rotor structure is mainly composed of a rotor core (1〇) disposed on a shaft (20); The rotor core (10) is formed by stacking Shishi steel sheets. ^ 6 M319579 The iron core (10) has a rotor end ring (U) at both ends, and at least one starting bar (12) passes through the rotor end ring (11). The rotor core is fixed; at least one set of W-type permanent magnets (13) is disposed in the rotor core (10), and the w-type permanent magnet groups (13) of different polarities are disposed adjacent to the rotor core (10). A Prq magnetic bridge (15) is further disposed between adjacent w-type permanent magnet groups (13), and the W-type permanent magnet group (13) is composed of radial and tangentially arranged permanent magnets (131) connected in parallel to the same polarity. The W-type hybrid architecture has an air gap (14) between the permanent magnet (i3i) and the permanent magnet (131). The permanent magnets (131) are fixed to the rotor core (1〇) through bolts (16). between. After the creation of the above structure is carried out, since the permanent magnet of the rotor is made of w-hybrid, the parallel-pole makes the rotor more heterogeneous, so that the rotor torque can be increased by 40% compared with the conventional one. The motor power density and the strange power of the motor are improved by the gain system; the excitation field of the starting coil of the scale is 'the rotor has the function of self-starting, the structure of the rotor is large, the production cost is reduced, and the rotor volume is reduced. Small 'increased range of motor design applications. Overall, this creation improves the utilization rate of permanent magnets and improves the overall operating efficiency of the motor. At the same time, it reduces the risk of _ _ cost, which has been selected as the default purpose, and has already met the needs of the industry. However, the present invention has been disclosed in the preferred embodiments described above, but it is not intended to limit the creation of the present invention.
