Description of the Invention: [Technical Field] The present invention relates to a micromotor, and more particularly to a micromotor that is easy to start. [Prior Art] A conventional motor generally includes a base, a rotor, and a certain subgroup. The base is provided with a shaft tube; the rotor is rotatably coupled to the shaft tube; the stator assembly is coupled to the base ' and the stator assembly is composed of a plurality of silicon steel sheets and coils; thereby, the stator assembly is energized After the magnetic field, it can be used to drive the rotor to rotate. However, in the actual use of the conventional motor, there is still a problem of difficulty in starting or starting to stop. Therefore, in order to solve the above problems, conventional motors which are conventionally known have a related structural design of 'easy to start'. In May, the signing of the brother 1 is shown in the Republic of China No. 1221〇48 “Using the stator local magnetic saturation effect to improve the motor that starts the dead point” patent case. The conventional motor has a stator 8 including a plurality of Shishi steel sheets stacked on each other. The steel sheet 81 has a plurality of radially extending extending portions 81 at the periphery thereof. Each of the extending portions 811 has a pole shoe 812 at the end. The pole shoe 812 forms an asymmetrical shape that can offset the magnetic flux with respect to its centerline two blocks: the stator 8 can generate an asymmetrical magnetic circuit for driving-rotating: to achieve the effect of no starting dead point. ^The waveform of the torque distribution, = 'on' knows that the stator 8 of the motor must form an asymmetric L relative to make each of the steel sheets & difficult, and increase the manufacturing cost; section, because the mosquitoes have 8 == 201117524 812, therefore, also results in a larger air gap between the materials (not shown). It is easy to affect the operating efficiency of the conventional motor. Moreover, today's motors are generally developed in the direction of miniaturization, etc., so that It is applied to various products of miniaturization; however, it is difficult to further reduce the overall axial height by the conventional motor with the stator 8 by the eight-phase height of several 81-phase steel plates and the overall structure is also quite complicated; It is also relatively limited to the feasibility of the conventional motor designed to be lighter, thinner and shorter. Also, as in the Republic of China No. 505337 "DC brushless motor easy to start construction" patent case, the system reveals the upper pole of the stator # and the lower pole A magnetic piece with an equiangular offset is provided. · For example, the patent case of the magnetic pole piece structure of the motor stator of the Republic of China No. 539346 discloses that the magnetic pole angle phase difference is formed between the first magnetic pole and the second magnetic pole of the patch group; in The Republic of China No. 55529 「 "The Stator Structure of Radial Winding" patent case reveals that the magnetic pole face of the stator pole piece is provided with a missing corner; for example, the "Motor Structure of Easy-Starting" patent case of the Republic of China No. 12879〇9 It is revealed that the magnetic pole faces of the stator group can form a strong magnetic region and a weak magnetic region. However, the above-mentioned conventional motors having the function of easily starting up are generally modified for the shape of each of the steel sheets (or pole pieces, magnetic poles, pole pieces, etc.) of the stator, so that the process is complicated and The manufacturing cost is relatively high, and the structure of each of the conventional motors is also quite complicated, and the stator also has a certain axial height, so that the conventional motors are not easily designed to be lighter, thinner and shorter. In order to improve the stator of the above various conventional motors, it is difficult to manufacture and the like. Another conventional motor has the same function as the easy-to-start function. Please refer to Figure 2 for the Republic of China No. 523219 "DC Brushless s] 201117524 Motor Easy Startup Structure" Patent Slaughter. - Base 91 and - Finance 92 = f Know the motor mainly includes), the ring The wall has several _% with - ring wall (not labeled), wherein the ring wall has another IC control (not drawn, the positioning hole _=;! = 911 has a positioning tie L,,, . ^ 疋a position member 913; the rotor 92 is slidably mounted on the base 91, and the rotor 92 has a permanent magnet ring 921 having a magnetic region. When the rotor 92 is rotated, the positioning member 913 is attached thereto. Magnetic field positioning in the strong magnetic region, the material n can not be improved: to achieve easy start function " can achieve the same work is to use the positioning member and 5 Xuan motor system directly to the base 91 tons 911; therefore ' The other conventional motor does not touch the stator formed by stacking a plurality of Shishi steel sheets, thereby simplifying the process. The ring wall of the base 91 of the other conventional motor must additionally form the positioning. The hole 912, in addition to causing the recording 91 to be difficult to manufacture, etc., the positioning member must be further along the axial direction of the rotor 92. Stretching a predetermined length such as two squares can be aligned with the coil group 911 disposed on the circumference of the base 91 L, resulting in an axial high yield of the base 91 incorporating the positioning member 913, and the subtraction is enhanced. The motor material is lighter and shorter, so it is necessary to improve it. ~ [Explanation] The object of the present invention is to improve the above disadvantages to provide a micromotor having an easy-to-start function, which can effectively reduce the micromotor The axial height is 201117524 degrees.

Thereby, the effect of maintaining the rotational balance of the rotor can be achieved as well. - an axial air gap is formed between the permanent magnet of the sub-group and the coil assembly. Thereby, the effect of reducing the structure and reducing the overall volume can be achieved. The coil set is a coil that is wired to the surface of the circuit board. Thereby, the effect of effectively reducing the axial height of the circuit board and simplifying the structural complexity of the circuit board can be achieved. The circuit board can be directly omitted, and the coil group and the detecting component are directly disposed on the substrate, and the auxiliary starting component is further provided with a bonding surface and a magnetic surface, and the splicing (four) is the same as the substrate The magnetic surface: facing the permanent magnet.
