Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, and in particular to a novel motor. Background Technology

[0002] Motors play a vital role in exercise equipment, especially in home and commercial treadmills and walking machines. Through electronic commutation technology, motors achieve efficient operation, providing continuous and even driving force to the treadmill belt. Whether the user is walking slowly, jogging, or sprinting at high speed, the motor can quickly respond to speed changes, ensuring smooth belt operation and preventing belt jamming or sudden changes in speed, thus improving the exercise experience and safety.

[0003] However, the exhaust port of the existing motor is located on the outer circle of the casing, which increases the processing cost of the casing and makes the exhaust and blowing form a straight line, increasing the noise of the air duct. At the same time, since the fan blades on the front cover are set inside the casing, the fan blades and the inner wall of the casing form a wedge-shaped band, which causes the wedge-shaped band to slip due to motor heat dissipation. Utility Model Content

[0004] In order to solve the technical problems of high processing cost of housing, increased airflow noise due to the straight line formation of exhaust and blowing, and wedge belt slippage caused by motor heat dissipation in the existing technology, this utility model provides a new type of motor.

[0005] The novel motor provided by this utility model adopts the following technical solution:

[0006] A novel motor includes a stator and a rotor rotatably disposed outside the stator. The stator includes a stator core, and a rotating shaft is fixedly disposed at the center of the stator core. The rotor includes a housing rotatably disposed outside the stator core. A front cover and a rear cover are respectively disposed at both ends of the housing. Multiple fan blades are evenly distributed on the surface of the front cover away from the housing. The fan blades are located outside the housing. Multiple through-holes are evenly distributed on the surface of the front cover. Multiple through-holes are evenly distributed on the surface of the rear cover.

[0007] Furthermore, insulating paper is provided on the stator core, and coils are wound around the outside of the insulating paper in the stator core.

[0008] Furthermore, a front end plate and a rear end plate are respectively provided at both ends of the stator core, and a Hall plate is provided outside the rear end plate. Bearings are provided outside both the front end plate and the Hall plate, and the bearings are sleeved on the outside of the rotating shaft.

[0009] Furthermore, the insulating paper is located between the front end plate and the rear end plate.

[0010] Furthermore, multiple magnets are evenly distributed between the stator core and the housing, and the magnets are fixedly connected to the housing.

[0011] Furthermore, the end of the housing near the front panel is fixedly connected to the front cover, and the end of the housing near the rear panel is fixedly connected to the rear cover.

[0012] Furthermore, the front end cover and the rear end cover are respectively fitted onto the bearings on both sides of the stator core, thereby realizing the rotational connection between the rotor and the stator.

[0013] Furthermore, the rear end cover and the front end cover are fixedly connected by screws.

[0014] In summary, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model eliminates the need for an external air duct corresponding to the fan blades on the outer side of the casing, creating a closed structure on the outer wall of the casing. This not only saves on casing manufacturing costs but also improves the integrity of the magnetic circuit and enhances motor performance. During operation, the rear cover acts as a fan, directing airflow into the motor for cooling, while the front cover acts as an exhaust fan, expelling air from the motor. This structure solves the problem of air duct noise caused by side air ducts on the motor casing.

[0016] 2. By placing the fan blades outside the housing, this utility model solves the problem of wedge belt slippage caused by motor heat dissipation, improves heat dissipation efficiency, solves the problem of driver overheating caused by motor heat dissipation, and reduces the air duct noise generated by the motor due to motor heat dissipation.

[0023] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0024] Example: Figures 1-5 The image shows a new type of motor.

[0025] Reference Figures 1-3 As shown, this utility model discloses a novel motor, including a stator and a rotor rotatably disposed outside the stator. Specifically, the stator includes a stator core 11, a rotating shaft 4 fixedly disposed at the center of the stator core 11, a front end plate 5 and a rear end plate 6 respectively disposed at both ends of the stator core 11, a Hall plate 8 for detecting the rotor angle disposed outside the rear end plate 6, and bearings 7 disposed outside both the front end plate 5 and the Hall plate 8. The bearings 7 are sleeved outside the rotating shaft 4. In use, the rotating shaft 4 and the stator core 11 are in a fixed state and do not rotate. Furthermore, insulating paper 12 is disposed on the stator core 11, the insulating paper 12 being located between the front end plate 5 and the rear end plate 6, providing insulation. A coil is wound around the outside of the insulating paper 12 in the stator core 11.

[0026] The rotor includes a housing 1 rotatably mounted outside the stator core 11. Multiple magnets 10 are evenly distributed between the stator core 11 and the housing 1, and the magnets 10 are fixedly connected to the housing 1. Further, a front cover 2 is fixedly connected to the end of the housing 1 near the front end plate 5, and a rear cover 3 is fixedly connected to the end of the housing 1 near the rear end plate 6. The front cover 2 and the rear cover 3 are respectively fitted onto bearings 7 on both sides of the stator core 11, thereby achieving a rotatable connection between the rotor and the stator. Moreover, the front cover 2 and the rear cover 3 cover both ends of the stator core 11. Specifically, the rear cover 3 and the front cover 2 are fixedly connected by screws 9. Further, the screws 9 fix the rear cover 3, the housing 1, and the front cover 2 into a single unit. In use, the coils in the stator core 11 generate magnetic force, driving the magnets 10 to rotate. The magnets 10 drive the housing 1, the front cover 2, and the rear cover 3 to rotate synchronously.

[0027] Specifically, refer to Figure 4 As shown, multiple fan blades 21 are evenly distributed on the surface of the front cover 2 away from the housing 1. The fan blades 21 are located outside the housing 1, and multiple through-holes 22 are evenly distributed on the surface of the front cover 2. This structural design eliminates the need for air ducts on the outside of the housing 1 corresponding to the fan blades 21, forming a closed structure on the outer wall of the housing 1. This not only saves on processing costs, but also improves the integrity of the magnetic circuit and enhances the performance of the motor.

[0028] Specifically, refer to Figure 5 As shown, multiple through-holes 31 are evenly distributed on the surface of the rear cover 3.

[0029] After the motor is started, the rear cover 3 acts as a fan to blow air into the motor to dissipate heat, while the front cover 2 acts as an exhaust fan to expel air from the motor. This structure solves the problem of airflow noise caused by the air duct set on the side of the housing 1.

[0030] This utility model solves the problem of wedge belt slippage caused by motor heat dissipation by setting the fan blade 21 on the outside of the housing 1, thereby improving heat dissipation efficiency. It also solves the problem of driver overheating caused by motor heat dissipation and reduces the air duct noise generated by the motor due to motor heat dissipation.

The various components mentioned in this utility model are common technologies in the existing field. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
