Description of the invention (1) The present invention is mainly for the permanent magnetic pole of the motor rotor with magnetically isolated slots. The structure of the magnet is to increase the magnetic field of the main pole under the effect of reducing the armature reaction and demagnetization effect, thereby increasing the output torque of the motor, so that the operation of the motor is more consistent with the high speed and the efficiency of the heavy load. According to the original patent, it is a permanent magnet motor composed of a stator and a rotor. The rotor uses an embedded permanent magnet to form the main magnetic pole. Among them, the main magnetic pole is provided with a plurality of magnetic isolation slots to improve the main magnetic pole reluctance. Effectively reduce the demagnetization effect of the armature reaction. This reduction of the demagnetization effect also reduces the influence of the armature reaction on the magnetic field of the main magnetic pole. The angular deviation of the neutral axis of the magnetic pole caused by the heavy load of the motor is reduced at the same time, and the motor The output torque and operating efficiency of heavy load operation to provide a permanent magnet motor with high speed and heavy load. The original patent has an embodiment in which the built-in permanent magnet constitutes the main pole. There is a permanent magnet with only a single side position. The structure [see the twenty-fourth figure of the original patent patent] and the synthetic excitation method of the angle formed by the permanent magnets on both sides [see the third picture of the original patent patent] The magnetic pole can obtain a stronger main pole magnetic field with only a single side permanent magnet. This can be input from Figure 22 and Figure 35 of the original patent drawings. Output torque ratio

The permanent magnet motor of the present invention is provided with a coil The slot (1A) 俾 line 圏 is composed of a three-phase winding stator (1) and a rotor (5), wherein the rotor (5) is a main magnetic pole (51) formed by an embedded permanent magnet, and the main magnetic pole (5 1) is provided There are multiple magnetically isolated slots (3), which can effectively reduce the demagnetization effect of the armature response and increase the output torque. In the present invention, the main pole magnetic field is raised under the aforementioned requirements to further increase the output torque. The rotor structure shown in the second figure has four main poles, and each main pole is formed by permanent magnets on both sides ( 21) (22) are arranged at an angle, and a third side permanent magnet (23) is arranged at the angle, so that the main magnetic pole is a three-side permanent magnet (2 1) (22) (23).

Description of the invention (4) There is an intermediate slot (4) in the neighbourhood printed by the employee consumer cooperative of the Central Directorate of the Ministry of Economic Affairs. The spacing and shape of the grooves are such that the magnetic flux path is not caused by the permanent magnet close to the middle empty groove portion, and the exciting magnetic fluxes of the three-side permanent magnets (2 1) (22) (23) are synthesized. Each main magnetic pole is also provided with a plurality of magnetically isolated slots (3). The magnetically isolated slots should also not cause the cogging effect of the rotor silicon steel sheet and the stator silicon cymbal sheet, and can reduce the rotational inertia of each main magnetic pole. When the motor rotor is rotating at high speed, the centrifugal force generated by each main magnetic silicon steel sheet is reduced. The third graph, the fourth graph, the fifth graph, and the sixth graph show the distribution and size of the magnetic flux distribution and the air-gap magnetic flux density in the radial direction of the motor of the present invention when the motor is not energized and energized. The magnetic flux of the time is interrupted by the magnetically isolated slot (3) and concentrated on the main magnetic pole (51). The interrupted magnetic flux is a path between the permanent magnet (23) and the motor core and shaft (6). Effectively reduce the influence of the energized excitation magnetic field of the stator wire on the main magnetic field, reduce the demagnetization effect of the armature reaction, and reduce the distortion caused by the main magnetic field. The seventh figure shows the output torque comparison table of the example of the present invention. The main magnetic poles are composed of the same three lateral permanent magnets and compared with whether or not a magnetically isolated slot is provided under the same operating conditions. The example of the present invention has significantly higher output torque. In addition, compared with the original example, it can be seen that the output torque of the example of the present invention is significantly improved. It is obvious that the present invention example is more in line with the operating efficiency of high speed and heavy load than the original example. As described above, under the original elements such as having a magnetically isolated slot to reduce the demagnetization effect of the armature reaction and to reduce the distortion caused by the main magnetic pole magnetic field, the embodiment of the present invention does improve the main magnetic pole magnetic field. The operating efficiency has been improved compared with the original case and is more in line with the operating efficiency of the motor.
