The operation principle of the application's internal rotor cooling type high-power eddy speed regulating device is as follows:
One, the soft connection of internal rotor and external rotor mainly relies on the eddy current on permanent-magnet and copper dish to realize
The rotation of the first permanent magnet 52 and the second permanent magnet 72, because drive conducting metal dish 91 rotates by magnetic force reason thereupon, drive internal rotor rotating disk 9 rotates by conducting metal dish 91, thus drives inner rotor shaft 3 to realize rotating, and namely achieves internal rotor and is connected with the soft of external rotor.
Two, the limit square in start-up course starts mainly the first latch member effect
When being in static or relative static conditions, suction makes external rotor moving coil 5 tend to internal rotor rotating disk 9, and the condition of work separated needed for and the minimal air gap selected, minimal air gap can regulate; When external rotor moving coil 5 rotates, centrifugal latch arms 59a arranges from its active position, and the limit square that can realize transmission device starts.
