By optimizing electromagnetic design, control algorithms and mechanical structure, it achieves high efficiency, energy saving and intelligent drive.
[0003] Currently, permanent magnet inverters generally use electromagnetic force and magnetic attraction for braking. If the power is interrupted, the electromagnetic braking will fail. If the braking effect fails, it will be inconvenient to use the integrated machine safely and greatly reduce its safety. To solve this problem, we propose a manual linkage permanent magnet inverter drive braking pin device. Utility Model Content

[0007] In a further embodiment, two second bearings are fixedly embedded in the inner wall of the second support frame, and a support shaft is fixedly connected to the inner rings of the two second bearings. An eccentric wheel frame is fixedly connected to the outer surface of the support shaft, and a traction steel wire rope is fixedly connected to the left side of the eccentric wheel frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This device, through its electromagnetic support, iron core, energized coil, armature, and magnetic disk, utilizes the principle of electromagnetic adsorption to move one end of the brake plate downwards. In conjunction with the connecting block, it moves the first clamping member downwards, contacting the surface of the circular friction wheel to achieve electromagnetic braking. Furthermore, through the traction steel cable, second bearing, support shaft, eccentric wheel frame, arc-shaped support plate, and second holding spring, the traction steel cable can be manually pulled, causing the eccentric wheel frame to rotate and contact the bottom surface of the circular friction wheel, thus clamping the wheel and achieving manual braking.

The bottom surface of the connecting block 19 is fixedly connected to the upper surface of the first clamping member 13. An electromagnetic bracket 7 is fixedly embedded in the upper surface of the first support frame 1. An iron core 71 is fixedly connected to the inner top wall of the electromagnetic bracket 7. An energized coil 72 is wound around the outer surface of the iron core 71. An armature 73 is fixedly connected to the bottom end of the iron core 71.

At the same time, the user can pull the traction steel wire rope 10 to pull the eccentric wheel frame 23, so that the eccentric wheel frame 23 pushes upward to hold the second clamping member 14 and contact the circular friction wheel 12 and clamp it, thus realizing the manual braking of the rotating shaft 11, completing the double braking of the rotating shaft 11.
