Description of the Invention: [Technical Field] The present invention relates to a structural improvement of a motor, particularly a motor in which an air gap between a stator and a rotor is adjustable. [Prior Art] Ο 〇 In the design of motors for a long time, the air gap (the magnetic energy induction gap between the rotor group and the stator group) has always been one of the important key parameters of the motor. The size of the air gap can dominate and change the motor. The performance of the output, such as · the torque level and the speed of the high and low. The design of the old motor is shown in Figure 3A or Figure 3B. The third A drawing is provided with the component of the rotating shaft A1 as the rotor A, the outer periphery of the rotor A is sleeved with a certain sub-B 'the rotor A and the stator 8 have an air gap d; the third b is provided with a rotating shaft A1 The component grain A', stator A, outer_set-rotor B, and 2A and rotor B have a gas_. Regardless of whether the rotor is on the periphery or the motor at the periphery, the stator and the rotor are parallel to each other. The distance between the two sensing surfaces (that is, the air gap d) is required to be fixed at the time of design.

The structure mainly includes a rotor and a stator. The present invention is not limited to a rotor and a stator. The tree having the shaft in the figure can be regarded as a ring-shaped element, which can also be regarded as a rotor or a stator. And this real _ is a definition? The element with the age u is the rotor 201039538 Ο Ο 1 'The ring element is the stator 2. Both sides of the rotor 1 and the stator 2 are designed to cooperate with each other to form a tapered surface. In general, the rotor! The outer tapered surface 12 is matched with the inner tapered surface 21 of the die 2, but the air gap d is left between the outer tapered surface 12 and the inner one. The size of the air gap d affects the output of the motor. Therefore, for the benefit of the rounding effect, the aperture d between the outer surface of the rotor outer surface 12 and the peak surface 21 of the stator 2 can be adjusted by moving the rotor 1 ' along the axis by adjusting the structure (not shown). As shown in Fig. AA, the rotor has been moved axially to the left in the direction of the dice 2; the first B is shown that the rotor 1 has been moved relative to the stator 2 in the direction of the rightward direction. State. The air gap d of the first-A diagram is lower than the air gap dA of the first-B diagram. The motor of the first-A diagram can produce small torsion and high-turning performance. The motor of the first-B diagram can generate high torque and low speed. Sexuality's look at the performance required by the user to adjust the air gap size. Further, the H-picture, the second A-picture and the second B-picture are respectively an exploded view and an operation diagram of the motor-independent embodiment of the present invention. In the present embodiment, the same component is used as the rotor ^, and the annular element is used as the rotor element. The difference between the rotor element 1' and the stator is the σ cone surface of the stator. The angle is smaller than the other embodiments, which is mainly intended to adjust the axial distance required for the expansion and contraction of the air gap by changing the tapered surface, and the stator and the rotor of the first and second A are tested.
