Description
Technical field
The present invention relates to magneto technical fields, and in particular to a kind of permanent magnet motor stator segment separator structure.
Background technique
The heavy duty equipments such as ball mill are commonly used already in China, the engineerings row such as building, mine, metallurgy
Industry also has more similar big machinery.Currently, most such mechanized equipments mainly use asynchronous motor, speed reducer and
Size starts the transmission mode of gear, these modes have the more disadvantages such as energy consumption is high, low efficiency, volume are big, maintenance complexity, existing
The performance level of weight equipment is transformed and promoted using magneto in more and more places.But existing magneto is used
In heavy-duty machinery driving, there are problems, such as need ultra-low speed big torsional moment output operation, need the air gap circle of driving motor
Week relatively will go out greatly many with power grade motor, and it is many unfavorable to bring to production, transport, installation, specific such as existing Permanent Magnet and Electric
Machine is mostly the base of monoblock type, is again inserted into rotor from end after inside installation stator, rotor itself has biggish magnetic force, pacifying
Just more difficult when dress, moreover rotor is mostly directly driven axis connection with it by this kind of heavy-duty machinery, so that the weight of rotor
Bigger, even up to tens tons, this makes rotor more difficult during installation or even does not fill, still slightly with existing structure and mode
There is misoperation to will result in the damage of rotor punching, stator punching or winding.Based on this, researching and developing one kind can be used for heavy-duty machinery
