Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a motor with high transmission efficiency. Background Art

[0002] The existing split motor stators are generally assembled together through concentric tooling and the equipment drive spindle. At the beginning of this assembly, the stator and the drive spindle are concentric. Because the motor or equipment will constantly experience impact, vibration and variable load when working, in this case, the screws locking the stator will loosen. As the number of vibrations continues to increase, the stator will be eccentric under the action of the magnetic field of the rotor. The consequence of stator eccentricity will lead to uneven magnetic field distribution, further leading to unstable motor current, excessive motor heating, and even coil burnout, motor jamming and other phenomena. Among them, a motor with application number "CN201510654604.2" has a motor rotor It is locked on the equipment or sewing machine drive spindle. The concentricity and positioning of the motor stator shape are achieved by matching the shape of the motor stator itself with the shape assembled on the corresponding equipment, and then the motor stator is fastened by anti-loosening screws. In this way, the motor stator and the equipment drive spindle and the motor rotor always maintain a concentric state, so that the motor can run stably and reliably. However, there is still room for improvement in the use of the motor: the micro-current motor will generate friction during actual use when working, and the heat generated by the friction will accumulate inside the motor. Since the heat dissipation structure of the motor relies only on its own casing, the heat dissipation effect is poor, and overheating of the motor will cause low transmission efficiency. Utility Model Content

[0003] The purpose of the utility model is to provide a motor with high transmission efficiency to solve the problem that the micro-current motor proposed in the above background technology will generate friction during actual use when working, and the heat generated by the friction will accumulate inside the motor. Since the heat dissipation structure of the motor only relies on its own shell, the heat dissipation effect is poor, and overheating of the motor will cause low transmission efficiency.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a motor with high transmission efficiency, comprising an outer shell, a heat dissipation component and an end cover;

[0005] Wherein: a stator core is fixedly mounted on the inner wall of the outer shell, a rotor winding is inserted in the middle of the stator core, and a rotating shaft is arranged in the middle of the rotor winding;

[0006] The heat dissipation assembly comprises a rotating disk fixedly mounted at the rear of the rotating shaft, a plurality of fan blades are welded around the surface of the rotating disk, and heat dissipation holes are opened between the fan blades on the surface of the rotating disk;

[0007] An end cover is fixedly mounted on the front end of the outer shell, and one end of the rotating shaft passes through the middle of the end cover.

[0008] As a preferred solution of the utility model: a mounting ring is fixedly installed on the inner side of the end cover, a bearing is embedded in the interior of the mounting ring, and the rotating shaft is rotatably installed in the middle of the bearing.

[0009] As a preferred solution of the utility model: mounting holes are correspondingly opened around the surface of the end cover and at the edge of the outer shell, and the internal threads of the mounting holes are connected with fixing screws.

[0010] As a preferred solution of the utility model: the stator core is composed of a plurality of stator punchings made of silicon steel.

[0011] As a preferred solution of the utility model: the surfaces of the outer shell and the end cover are correspondingly provided with flow-conducting holes.

[0012] As a preferred solution of the utility model: a junction box is installed on the outer wall of the outer shell.

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

[0014] (1) A rotating disk is installed at the tail of the rotating shaft. When the rotating shaft rotates, the rotating disk is driven to rotate. The rotation of the rotating disk drives the fan blades on the surface to rotate. The rotation of the fan blades transports the external airflow to the inside of the outer shell. The airflow passes through the stator core and the rotor winding and takes away the heat, reducing the heat generated by friction during the use of the motor, so as to cool the inside of the motor, thereby preventing the motor from running under overheating and ensuring the motor's continuous high transmission efficiency;

[0015] (2) Mounting holes are provided on the surface of the end cover and the edges of the outer shell. After the mounting holes on the surface of the end cover correspond to the mounting holes on the edges of the outer shell, fixing screws are threaded into the mounting holes to fix the end cover to the outer shell.

The rotation of the rotating disk 501 drives the fan blades 502 on the surface to rotate. The rotation of the fan blades 502 transports the external airflow to the inside of the outer shell 100. The airflow passes through the stator core 200 and the rotor winding 300 to take away the heat, reducing the heat generated by friction during the use of the motor, so as to cool down the inside of the motor, thereby avoiding the motor from running in an overheated state and ensuring the motor's continuous high transmission efficiency.
