Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a disc motor with a braking function. Background Art

[0002] The disc motor is a special type of motor whose stator and rotor are both designed in the shape of a disc. Compared with traditional motors, the disc motor has higher power density, higher efficiency and smaller size. This design makes the disc motor have a wide range of application prospects in applications that require high power output, such as electric vehicles, aircraft and other fields that require high-performance drive systems.

[0003] The disc-type single-phase brake split-phase high-power motor is developed on the basis of domestic three-phase disc-type motors with reference to international standards. Because the traditional column-type single-phase motors are mostly started and operated by mechanical centrifugal switches, they have the disadvantages of short service life and high failure rate, and cannot be installed on single-phase disc motors with brakes. Therefore, through scientific research and cooperation, a single-phase split-phase brake-type high-power single-phase motor has been developed. Its working principle is the same as that of traditional single-phase asynchronous motors. This disc-type and brake motor is easy to use. It only needs to provide a power supply in the range of 190 volts to 230 volts, and it can start quickly, brake accurately, have low power consumption, high power factor, high efficiency and energy saving, low noise, etc. It is waterproof, oil-proof and various harsh environments, and can be used as a submersible type and underwater operations.

[0004] The traditional column single-phase motor is started and operated by capacitors and mechanical centrifugal switches. If the mechanical centrifugal switch is installed on the rotor of the disc motor, the expected goal cannot be achieved. However, the mechanical centrifugal switch on the single-phase motor has a high failure rate, a short service life, is easily damaged and is not explosion-proof. Therefore, on the basis of the three-phase brake motor, a single-phase disc brake motor is obtained. This motor is energy-efficient, low-noise, waterproof, explosion-proof, and oil-proof. It can also be made into a submersible disc motor. It can also be used in electric zipper hoists, that is, electric hoists.

[0005] During the use of the existing disc motor, it is not convenient to perform rapid braking after the disc motor is powered off, which increases the potential danger and the occurrence of accidents and reduces the safety of the disc motor. Utility Model Content

[0006] The purpose of the utility model is to provide a disc motor with a braking function, which has the advantage of automatic braking and solves the problem that the existing disc motor is not convenient to brake quickly after the disc motor is powered off during use, which increases the occurrence of potential dangers and accidents and reduces the safety of the disc motor.

[0007] To achieve the above object, the utility model provides the following technical solution: a disc motor with a braking function, comprising a housing, a base mounted on one side of the housing, a stator mounted on one side of the base, a coil package on the surface of the stator, a rotor mounted on one side of the stator, a rotor assembly mounted on the inner wall of the rotor, a rotating shaft mounted inside the rotor assembly,

[0008] A spring sleeved on the surface of the rotor assembly is provided on the right side of the base, and a brake pad is installed on the inner wall of the shell.

[0009] As a preferred disc motor with a braking function of the utility model, one end of the rotating shaft extends to the outside of the base, a plurality of bearings are installed between the rotating shaft and the base, and a bearing cover for sealing the rotating shaft is provided on the base.

[0010] As a preferred embodiment of the disc motor with braking function of the utility model, the brake pad is circular and is located on the right side of the rotor.

[0011] As a preferred embodiment of the disc motor with braking function of the utility model, a key is provided on the surface of the rotating shaft.

[0012] As a preferred embodiment of the disc motor with braking function of the utility model, the inner diameter of the spring is larger than the diameter of the left end of the rotor assembly.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model can perform rapid braking after power failure by arranging springs on the opposite side of the base and the rotor. After power failure, the magnetic field of the stator disappears and the rotor is no longer under force. At this time, the spring stretches to drive the rotor assembly to move, and the rotor assembly drives the rotor to move toward the brake pad. The brake pad and the rotor frictionally brake it to prevent the shaft from continuing to rotate. Rapid braking can quickly stop the rotation of the disc motor, reducing potential dangers and accidents. Especially in certain emergency situations, such as emergency shutdown or emergency braking, rapid braking can help prevent equipment damage, casualties or other accidents.

[0017] See also Figure 1A disc motor with a braking function comprises a shell 1, a base 9 is mounted on one side of the shell 1, a stator 8 is mounted on one side of the base 9, a coil 12 is mounted on the surface of the stator 8, a rotor 7 is mounted on one side of the stator 8, a rotor assembly 3 is mounted on the inner wall of the rotor 7, and a rotating shaft 11 is mounted inside the rotor assembly 3.

[0018] Furthermore, a spring 2 sleeved on the surface of the rotor assembly 3 is provided on the right side of the base 9, and a brake pad 4 is installed on the inner wall of the housing 1.

[0019] Furthermore, one end of the rotating shaft 11 extends to the outside of the base 9 , a plurality of bearings 6 are installed between the rotating shaft 11 and the base 9 , and a bearing cover 10 for sealing the rotating shaft 11 is provided on the base 9 .

[0020] Furthermore, the brake pad 4 is circular and is located on the right side of the rotor 7 .

[0021] Furthermore, a key 5 is provided on the surface of the rotating shaft 11 .

[0022] Furthermore, the inner diameter of the spring 2 is larger than the diameter of the left end of the rotor assembly 3 .

[0023] By arranging the spring 2 on the opposite side of the base 9 and the rotor 7, rapid braking can be performed after power failure. After power failure, the magnetic field of the stator 8 disappears, and the rotor 7 is no longer under force. At this time, the spring 2 stretches to drive the rotor assembly 3 to move, and the rotor assembly 3 drives the rotor 7 to move toward the brake pad 4. The brake pad 4 and the rotor 7 rub against each other to brake it quickly to prevent the shaft 11 from continuing to rotate. Rapid braking can quickly stop the rotation of the disc motor, reducing potential dangers and accidents. Especially in certain emergency situations, such as emergency shutdown or emergency braking, rapid braking can help prevent equipment damage, casualties or other accidents.

[0024] When the motor is energized, the rotor 7 approaches the stator 8 due to the interaction of the magnetic fields. In the motor, the magnetic field is generated by the current passing through the coil 12, and a magnetic field gap is formed between the rotor 7 and the stator 8. The magnetic field generated by the excitation current on the stator 8 is fixed, and the rotor will also generate a magnetic field after being energized. According to the law of action of the Lorentz force, when the two magnetic fields interact with each other, a force will be caused, so a force will be generated to make the rotor 7 approach the stator 8 to squeeze the spring 2, thereby releasing the brake pad 4 on the rotor 7.

[0025] After the coil 12 is wound around the stator 8 and energized, a magnetic field can be generated. This magnetic field interacts with the permanent magnet or other magnetic materials on the rotor 7, so that the rotor 7 is acted upon by a force, thereby generating a rotational motion, driving the shaft 11 to rotate at high speed.

[0026] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
