Definitions
- the utility model relates to a motor structure, and more particularly to a motor magnet fixing structure.
- the basic structure of the motor generally includes a casing, a rotor, and a magnet (stator).
- the basic structure of the motor is assembled by basically positioning one end of a magnet by using two positioning elements preset inside the housing, so that the two magnets are positioned at the relative positions of the inner wall of the outer casing, and at least one separation is provided between the other ends of the two magnets. The component is then completely fixed in the housing and then placed in the rotor.
- the magnet Since the magnet is placed on the inner wall of the outer casing, it can be called a built-in magnet, and the motor with the built-in magnet is faced with a large obstacle when assembling the rotor, because the magnet acts magnetically with the rotor, so that the rotor is It is easy to get off the axis and get stuck on the outer casing during the process of inserting the outer casing, so it is necessary to go through many failures in the assembly process to achieve the assembly of the axial alignment.
- An object of the present invention is to provide a motor magnet fixing structure for improving the above-described built-in magnet to hinder the assembly of the rotor, and to make the assembly more convenient and reliable.
- the casing is provided with two magnet fixing portions at opposite positions;
- magnets for supplying magnetic force to the rotor are respectively disposed in the two magnet fixing portions.
- the magnet fixing portion is a hole that penetrates the thickness of the outer casing.
- the magnet fixing portion is a groove structure disposed on an outer surface of the outer casing.
- the magnet is tightly fitted and fixed to the opposite periphery of the magnet fixing portion.
- the magnet and the at least two peripheral portions of the magnet fixing portion have a sloped structure for tightly fitting and fixing the two.
- At least two peripheral portions of the magnet are correspondingly coupled to the planar structure around the magnet fixing portion, and have an outer circular arc structure for tightly fitting and fixing between the two.
- one is used to provide an external restraining force to the two magnets, thereby preventing the magnet from coming off the bundle of the magnet fixing portion, and sheathing the outside of the outer casing.
- the magnet since the magnet is disposed on the outer wall of the outer casing, it can be It is called an external magnet, and the motor constructed by an external magnet can completely solve the problem of assembling the rotor as described in the prior art.
- Figure 1 is a perspective view of the first embodiment of the present invention.
- Figure 2 is an exploded perspective view of the first embodiment of the present invention.
- Figure 3 is a combined cross-sectional view of the first embodiment of the present invention.
- Figure 4 is an external view of a second embodiment of the present invention.
- Figure 5 is an exploded perspective view of a second embodiment of the present invention. detailed description
- the motor of the present invention mainly comprises a casing 10, a rotor 11 and two magnets 12, 13, and a bundle 14.
- the outer casing 10 is provided with a pair of magnet fixing portions 20 at opposite positions for the purpose of accommodating the two magnets 12, 13.
- the magnet fixing portion 20 may be a hole penetrating into the inner portion of the outer casing 10 as shown in the drawing, or may be a groove structure disposed on the outer surface of the outer casing 10, and if it is a groove structure, the outer casing is provided with the groove.
- the remaining wall thickness allows the magnetic force of the magnets 12, 13 to be transmitted to the rotor 11 through the wall thickness.
- the motor configuration shown in Figs. 1, 2, and 3 further includes a brush holder 15 and a tail cap 16 which are disposed at the rear end of the outer casing 10.
- the motor of the present invention is assembled by first arranging the rotor 11 in the casing 10, and then arranging the two magnets 12 and 13 on the magnet fixing portion 20, respectively, and then sheathing the bundle 14 to the outside of the casing 10.
- the two magnets 12, 13 are constrained from disengagement from the outer casing 10.
- the magnets 12, 13 are disposed on the outer wall of the outer casing 10, they can be referred to as external magnets, and the motor of the external magnet structure can completely avoid the problem of assembling the rotor as described in the prior art.
- the rotor 11 is first disposed in the outer casing 10, and then the two magnets 12, 13 are assembled.
- the rotor 11 is assembled, since there is no magnetic force of the two magnets, the card stuck on the outer casing is not generated in the prior art.
- the problem is that when the two magnets 12 and 13 are provided in the magnet fixing portion 20, they are magnetically attracted to the rotor 11 and are adsorbed and positioned, and the magnetic structure of the motor is assembled.
- the motor of this embodiment mainly includes a casing 30, a rotor 31, and two magnets 32, 33 and a bundle 34.
- the outer casing 30 is provided with a pair of magnet fixing portions 40 at opposite positions for the purpose of fixing the two magnets 32, 33.
- the magnet fixing portion 40 may be a hole penetrating into the inside of the outer casing 30 as shown in the drawing, or may be a groove structure disposed on the outer surface of the outer casing 30. In the case of the groove structure, the remaining thickness of the outer casing 30 after the groove is provided allows the magnetic force of the magnets 32, 33 to be transmitted to the rotor 31 through the wall thickness.
- the magnets 12 and 13 of the motor 10 are provided in the magnet fixing portion 20, the magnets 12 and 13 are also attached to the magnet fixing portion 20 except for the magnetic force of the rotor 11 and the magnets 12 and 13 being adsorbed and fixed. A circumferential relationship is generated.
- the magnets 12, 13 and at least two peripheral portions of the magnet fixing portion 20 have correspondingly configured beveled structures 21, 131 for magnets 12, 13 and magnet fixing portions. A tight fitting relationship is formed around the periphery of 20, and the magnets 12, 13 are fixed.
- at least two peripheral portions of the magnets 12, 13 may also have an outer circular arc structure, and corresponding to the planar structure around the magnet fixing portion 20, the fixing effect of the tight joint can also be achieved.
- the tight positioning relationship between the magnets 12, 13 and the periphery of the magnet fixing portion 20 can also be achieved in any other possible form.
- the application of the bundle 14 is as the case may be, and in principle the bundle 14 may be of various types and is not limited to those depicted in the drawings.
- the bundle 14 can provide a magnet 12, 13 - a restraining external force which, when the motor is running, does not disengage from the outer casing due to magnetic repulsion.
- the application of the beam shape-matching material as shown in the figure can achieve the function of blocking the release of magnetic force to the space outside the casing to ensure the relative magnetic force between the rotor and the magnet.
- outer casing 10 of the present invention may be made of metal or plastic.
