Description

Technical Field

[0001] The utility model relates to the technical field of conical motors, in particular to a small conical motor. Background Art

[0002] A conical rotor brake motor is a three-phase asynchronous motor with a built-in brake and a conical stator and rotor. Both the stator cavity and rotor are conical in shape. Because the brake of a conical motor has a certain size, it results in a large conical motor. This application reduces the size of the brake by directly attaching it to the rotor, thus reducing the size of the conical motor and thus reducing its production cost. Utility Model Content

[0003] The purpose of the present utility model is to provide a small conical motor to solve the problem in the background art that the conical motor has a large size due to the brake part of the conical motor having a certain size.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a small conical motor, comprising: a front cover and a rear cover, the head of the front cover is embedded with a baffle cover, the interior of the baffle cover is connected through a rotor, the middle of the rotor is installed with a stator, the tail end of the rotor is installed on a ring, the ring is installed on the rear cover, and a brake assembly is installed between the stator and the rear cover.

[0005] Preferably, the brake assembly includes an elastic member and a brake plate, and the tail end of the elastic member is connected to the brake plate.

[0006] Preferably, the head of the elastic member is mounted on the stator via a fastener.

[0007] Preferably, the brake plate is in an inclined structure and is attached to the inner wall of the rear cover.

[0008] Preferably, a shaft circlip is installed inside the rear cover, and a rotor passes through the shaft circlip.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: the small conical motor directly installs the elastic part and the brake plate on the stator. When the conical motor is energized, the rotor drives the stator to retract the brake plate and separate from the inner wall of the rear cover and rotate. When the power is cut off, the rotor drives the stator to restore the original brake plate and contact the rear cover under the drive of the spring, so that the brake plate and the rear cover are braked. This solution reduces the size of the conical motor and reduces the production cost of the conical motor. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 This is a schematic diagram of the main internal cross-sectional structure of the utility model.

[0011] In the figure: 1. front cover; 2. baffle cover; 3. rotor; 4. stator; 5. ferrule; 6. rear cover; 7. circlip for shaft; 8. elastic part; 9. brake plate. DETAILED DESCRIPTION

[0012] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0013] See also Figure 1 The utility model provides a technical solution: a small conical motor, comprising: a front cover 1 and a rear cover 6, a baffle 2 is embedded in the head of the front cover 1, a rotor 3 is connected to the inside of the baffle 2, a stator 4 is installed in the middle of the rotor 3, the tail end of the rotor 3 is installed on a ring 5, the ring 5 is installed on the rear cover 6, and a brake assembly is installed between the stator 4 and the rear cover 6.

[0014] The brake assembly includes an elastic member 8 and a brake plate 9 . The tail end of the elastic member 8 is connected to the brake plate 9 . The brake assembly can brake the stator 4 .

[0015] The head of the elastic member 8 is mounted on the stator 4 through a fastener. When the elastic member 8 is mounted on the stator 4, the elastic member 8 can be driven to move simultaneously when the stator 4 is secured.

[0016] The brake plate 9 is in an inclined structure and fits on the inner wall of the rear cover 6, so that the inner side wall of the brake plate 9 is completely in contact with the inner wall of the rear cover 6, thereby making the brake plate 9 contact and brake the rear cover 6, which can brake the rotation of the stator 4.

[0017] A shaft circlip 7 is installed inside the rear cover 6 , and the rotor 3 passes through the shaft circlip 7 . The shaft circlip 7 can prevent the rotor 3 and the bearing in the ring 5 from axial movement.

[0018] In summary: Figure 1 As shown, when using the small conical motor, first power is supplied to the conical motor, and the motor drives the rotor 3 to extend and retract. When the rotor 3 extends and retracts, the rotor 3 drives the stator 4 to move, thereby separating the brake plate 9 from the rear cover 6. When the power is cut off, the rotor 3 returns to its original position, and the rotor 3 drives the stator 4 to return to its original position, so that the brake plate 9 fits against the inner wall of the rear cover 6 again, thereby achieving braking of the stator 4 until the stator 4 stops. This is the characteristic of the small conical motor.

[0019] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
