Description

Technical Field

[0001] The utility model relates to the technical field of brushless motors, and particularly relates to an industrial integrated brushless motor. Background Art

[0002] A brushless DC motor consists of a motor main body and a driver, and is a typical mechatronic product. The brushless DC motor operates in a self-controlled manner, so it does not have an additional starting winding on the rotor like a synchronous motor under variable-frequency speed regulation during heavy-load starting, nor does it generate oscillations and loss of steps when the load changes suddenly.

[0003] For a Chinese patent with the application publication number CN215498504U, an industrial integrated brushless motor, when in use, first, when using the device, the motor is taken out and placed at a designated position, then the clamping block is engaged and fixed with the motor for the heat dissipation fins, and then the first positioning rod is used to thread-fix the heat dissipation fins. When using the device, the heat dissipation fins are provided to facilitate heat dissipation of the device. Then, the fixing bolt is used to disassemble the sliding sleeve, and the sliding sleeve and the pulley are used to adjust the height of the sliding rod to a designated position, and then the fixing bolt is used to fix the sliding sleeve. When using the device, the sliding sleeve is provided to facilitate adjustment of the height of the device. Finally, the motor is used.

[0004] To solve the problem of inconvenient heat dissipation of the device in the above technical solution, the prior art is to use heat dissipation fins to dissipate heat from the device, but there will still be a situation where the outside of the connector lacks protection, which may lead to the problem that the connector is damaged by external impact when the brushless motor is not in use. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an industrial integrated brushless motor to solve the problems put forward in the above background art.

[0006] To solve the above technical problems, the technical solution adopted by the utility model is:

[0012] A further improvement of the technical solution of the present utility model lies in that: a bearing is sleeved in the middle of the stator core, the bearing is sleeved outside the crankshaft, and the bearing is sleeved outside the crankshaft to fix the position of the crankshaft.

[0013] A further improvement of the technical solution of the present utility model lies in that: the connection mechanism includes a circuit board, the circuit board is fixedly connected to the copper coil, the upper surface of the circuit board is fixedly connected to the lower surface of the bearing, the circuit board is fixedly connected to the bottom of the permanent magnet, and the circuit board is sleeved outside the crankshaft.

[0015] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model compared with the prior art is:

[0016] The present utility model provides an industrial integrated brushless motor. When the brushless motor is not in use, the protection plate is pushed into the inside of the connecting plate, so that the protection plate is attached to the plastic suction cup, thereby fixing the position of the protection plate. The protection plate is located directly above the circuit board, can cover the entire circuit board, can protect the connector, and at the same time reduce the entry of dust into the connector, thereby avoiding damage to the connector due to external impact, and playing a protective role for the brushless motor.

The left side of the bottom plate 18 is fixedly connected with an anti-slip pad 19;

[0025] Specifically, when the brushless motor is not in use, the protective plate 14 is pushed into the inside of the connecting plate 11, so that the protective plate 14 is attached to the plastic suction cup 17, thereby fixing the position of the protective plate 14. The protective plate 14 is located directly above the circuit board 31 and can cover the entire circuit board 31, so as to protect the connector 33 and prevent the connector 33 from being damaged by external impact. When pushing the protective plate 14, the L-shaped support rod 15 supports the protective plate 14. While pushing, the plastic rotating beads 16 rotate inside the second chute 13 and the L-shaped support rod 15, which can improve the smoothness of the movement of the protective plate 14. At the same time, the end of the L-shaped support rod 15 can limit the movement range of the protective plate 14, thereby preventing the protective plate 14 from falling out of the inside of the connecting plate 11.

In order to insulate the stator core 24 from the copper coil 25, its surface will be provided with a resin coating. The bearing 26 is used to fix the bearing of the crankshaft 23 and improve the tightness of the connection of the components inside the motor body mechanism 2.

Subsequently, connect the external circuit to the connector 33, so that the external circuit is connected to the circuit on the circuit board 31. If a device that needs to rotate needs to be installed outside the brushless motor, install the device that needs to rotate at the threaded end of the crankshaft 23, and the device can be driven to rotate when the brushless motor is running.
