[0027] See also Figure 1-4 As shown, the utility model is a suspended permanent magnet synchronous motor, comprising a motor body 1 and a fixed seat 2, a connecting shaft 3 is rotatably mounted on the fixed seat 2, a polygonal sleeve 4 is fixedly arranged at the bottom of the connecting shaft 3, and also comprises a suspension seat 5 located between the motor body 1 and the fixed seat 2, a rotating polygonal rod 6 is rotatably arranged on the suspension seat 5, a buffer spring 18 is arranged between the polygonal sleeve 4 and the polygonal rod 6, a rectangular hole 10 is opened at the connecting end of the motor body 1, a rectangular block 11 is inserted into the rectangular hole 10, a positioning block 12 is fixed to the upper end of the rectangular block 11, and a locking block 13 is fixed to the upper end of the positioning block 12.

[0028] Among them, the polygonal rod 6 is plug-connected with the polygonal sleeve 4, a telescopic sleeve 7 is fixed to the bottom of the fixed seat 2, a telescopic rod 8 is provided in the telescopic sleeve 7, a positioning ring 9 is fixed to the lower end of the telescopic rod 8, and the bottom of the telescopic rod 8 is fixedly installed with the suspension seat 5. In this embodiment, the polygonal sleeve 4 and the polygonal rod 6 neither affect the transmission of power nor provide an axial buffer space, thereby better protecting the motor body 1.

[0029] Among them, the output end of the motor body 1 drives the connecting shaft 3 to rotate through the polygonal sleeve 4 and the polygonal rod 6, and a movable space for the polygonal rod 6 is vacated inside the telescopic sleeve 7, and a minimum limit piece is provided between the telescopic rod 8 and the telescopic sleeve 7. In this embodiment, the limit piece between the telescopic sleeve 7 and the telescopic rod 8 is used to vacate the upward movable space of the motor body 1, thereby forming a buffered energy absorption space in the movable space.

[0030] There are multiple telescopic sleeves 7 and telescopic rods 8, which are evenly distributed between the fixed seat 2 and the suspension seat 5. In this embodiment, multiple telescopic sleeves 7 and telescopic rods 8 ensure structural reliability during buffering.

[0031] Among them, the rectangular block 11, the positioning block 12, and the locking block 13 are fixed to the motor body 1 by nuts, and a through hole for inserting the positioning block 12 and the locking block 13 is opened on the suspension seat 5. In this embodiment, the rectangular block 11, the positioning block 12, and the locking block 13 are all rectangular structures, which ensures precise docking with the through hole in the suspension seat 5, and can also reliably cooperate with the locking seat 14.

[0032] Among them, a locking seat 14 is slidably provided on the suspension seat 5, a plurality of locking plates 15 are fixed on the locking seat 14, a pull ring 16 is also fixed on one side of the locking seat 14, and a locking spring 17 is also provided between the suspension seat 5 and the locking seat 14. In this embodiment, the plurality of locking plates 15 are connected through the locking seat 14, so that the motor body 1 can be fixed on the suspension seat 5 from multiple positions to ensure the connection reliability.

[0033] Among them, the locking seat 14 is inserted between the positioning block 12 and the locking block 13 through the locking spring 17. In this embodiment, a single locking spring 17 can be used to limit the position of multiple positioning blocks 12 and locking blocks 13 on the suspension seat 5, thereby conveniently fixing the motor body 1 on the suspension seat 5.

[0034] It can be understood that, firstly, the buffer between the fixed seat 2 and the suspension seat 5 can absorb energy when the motor body 1 is hit, thereby avoiding or reducing damage to the motor, while not affecting the normal operation of the motor; secondly, the provided clip structure can improve the convenience of suspension and disassembly of the motor body 1, while ensuring the reliability of the connection.

[0035] A specific application of this embodiment is: the polygonal rod 6 rotates on the suspension seat 5, and an axial plug-in connector is provided between the bottom and the output end of the motor body 1, the connector is a non-circular structure, and can be the same structure as the polygonal sleeve 4 and the polygonal rod 6;

[0036] Assembly of the suspended motor: the telescopic sleeve 7 is fixed to the fixed seat 2 by a nut, the buffer spring 18 is placed inside the polygonal sleeve 4, the telescopic rod 8 slides inside the telescopic sleeve 7, and the telescopic sleeve 7 is fixed to the suspension seat 5 by a nut. At this time, the buffer parts between the fixed seat 2 and the suspension seat 5 are assembled, and the connecting shaft 3 is connected to the power input shaft of the equipment by a coupling, etc. The fixed seat 2 is fixed to the equipment in a suspended state by bolts, and the output end of the motor body 1 is facing the suspension seat 5. The locking seat 14 is pulled by the pull ring 16 to disengage the locking plate 15 from the side of the hole in the suspension seat 5, and the motor body 1 is pushed upward. At this time, the locking block 13 passes through the suspension seat 5, and the positioning block 12 is located in the suspension seat 5. After loosening the pull ring 16, the locking plate 15 is driven by the locking spring 17 to be stuck between the positioning block 12 and the locking block 13. During the docking process, the connecting parts between the output end of the motor body 1 and the polygonal rod 6 are docked, and the motor body 1 is installed.

[0037] When working, the motor body 1 outputs power and drives the connecting shaft 3 to rotate through the connecting piece, the polygonal rod 6, and the telescopic sleeve 7, and the connecting shaft 3 drives the device;

[0038] When the motor body 1 needs to be repaired, the locking plate 15 is disengaged from between the positioning block 12 and the locking block 13 after pulling the pull ring 16, and the motor body 1 can be taken out by turning it downward.
