The invention discloses a disk-type permanent magnetic
speed regulator. The disk-type permanent magnetic
speed regulator comprises a first shaft and a second shaft which are coaxially arranged in a split mode. The end of the first shaft is connected with sliding blocks and conductor disks through a speed regulation mechanism. The conductor disks are made of materials with good
conductivity. The end of the second shaft is connected with a permanent magnetic rotary disk through a load connecting disk. Permanent magnets are mounted on the permanent magnetic rotary disk and are arranged between the conductor disks. According to the disk-type permanent magnetic
speed regulator, the structure of a permanent magnetic rotor is simplified, and the disk-type permanent magnetic speed
regulator is only provided with one permanent magnetic rotary disk, so that the weight of the permanent magnetic rotor is greatly reduced on the basis of achieving air gap regulation, and the permanent magnetic rotor is more stable in the rotating process; consequently, mechanical friction and
mechanical abrasion are reduced, interference of vibration is avoided, loss of transmission components is reduced, vibration is isolated, and
noise is lowered; meanwhile, the disk-type permanent magnetic speed
regulator is easy to install and debug, free of precise centering, capable of allowing a certain axial movement, and capable of changing output rotating speed and achieving the purposes of speed regulation and
energy conservation through the design of two kinds of speed regulation mechanisms, and the size of air gaps can be controlled more accurately.
