State is adjusted, and the ability for further increasing washing machine rotor operation stationarity is limited.It is usually used in motor and wheel movement of the foetus at present
Balance adjustment method is usually offline adjustment mode, cannot carry out active accommodation according to the non-equilibrium state of load in real time.And lead to
Increase mode of the movement mechanism from main modulation mass block position in rotor is crossed, due to increasing mechanical structure, in operational process
In there may be additional noises, and due to the moist changeable use environment of washing machine, service life is difficult to ensure.For
The problems in the relevant technologies, currently no effective solution has been proposed.
Summary of the invention
The object of the present invention is to provide one kind to realize the laundry on-line automatic tune of machine rotor by the way that electromagnetic drive mass block is mobile
Whole dynamic balance method, to overcome currently available technology above shortcomings.The purpose of the present invention is pass through following technical side
Case is realized: installing ring-shaped guide rail in laundry machine rotor, uniformly installation can independently adjust the electricity of current switching around guide rail
Magnet, the permanent magnet mass block that installation can be slided along guide rail in guide rail is amesiality in the quality for detecting laundry machine rotor
When, by gradually adjusting the on-off of different electromagnet in rotor, keep the permanent magnetism mass block in guide rail mobile to assigned direction, adjustment
The Mass Distribution situation of rotor, to realize the online real-time adjustment of rotor dynamic balancing state.
Preferably, the dynamic equilibrium state of rotor is detected, the position for needing to carry out dynamic balancing compensation is calculated and active force is big
It is small；The on off operating mode for gradually adjusting each electromagnet moves the magnetic mass block in track to assigned direction.By in track
The change of magnetic mass block position, adjusts the Mass Distribution of rotor, so as to adjust the dynamic equilibrium state of rotor, when reducing its rotation
Vibration and noise.
Preferably, multiple electromagnet can individually control each electromagnet along cyclic annular sliding rail even circumferential distribution
In current switching, gradually mass block to be driven to move.
Preferably, magnetic mass block is permanent magnet, is placed in orbit as needed one or more.
Preferably, settable identical size or various sizes of multiple groups track adjust more according to the program being pre-designed
The position of mass block makes a combination thereof generate different centrifugal force in a track.
