As shown in Figure 1, magnetize outward in technical process, usual elder generation inserts magnet steel 20 ' in advance rotor 10 ', to form loop of magnetizing, the external diameter design of rotor 10 ' is less than the internal diameter of magnet steel 20 ', namely the magnetic gap designed, ensures that rotor 10 ' can not touch magnet steel 20 ' during High Rotation Speed in magnet steel 20 ', also facilitates rotor 10 ' to the assembling of magnet steel 20 '.But the process of magnetizing is an instantaneous pressure discharge process, before magnetizing, be in free state, in skewed at magnet steel 20 ' internal rotor 10 '; The moment of magnetizing, rotor 10 ', by specific magnetic pull F, clashes into the edge of magnet steel 20 ' instantaneously from external diameter direction, thus easily causes magnet steel 20 ' cracked.
Utility model content
For overcoming the defect existing for prior art, now provide a kind of magnetic steel of motor to magnetize protective device, magnetize in technical process to solve outside existing motor, rotor easily crashes the problem of magnet steel.
For achieving the above object, a kind of magnetic steel of motor magnetizes protective device, comprising: the limiting plate being erected on the port of motor stator; Be arranged on described limiting plate, for the spacing hole that armature spindle runs through.
The magnetize further improvement of protective device of the utility model magnetic steel of motor is, described limiting plate comprises: be depressed in the limiting plate body in described stator; Be overlapped in the lapping plate of described port; Be arranged at the inwall of described stator, be connected to the connecting plate of described lapping plate and described limiting plate body; Described spacing hole is arranged on described limiting plate body.
The magnetize further improvement of protective device of the utility model magnetic steel of motor is, described limiting plate body is plectane, and the diameter of described plectane equals the internal diameter of described stator.
The magnetize further improvement of protective device of the utility model magnetic steel of motor is; the described limiting plate body side's of comprising plate and be arranged at two meniscuss of described side's plate both sides; wherein, the length of described side's plate and two meniscal action sums equal the internal diameter of described stator.
The beneficial effects of the utility model are, before in rotor insertion magnet steel, preparation is magnetized, limiting plate is erected on the port of motor stator, armature spindle is through spacing hole, make armature spindle no longer in skewed, stopped rotor and clashed into the risk of magnet steel in the process that magnetizes, and then solved outside existing motor and magnetize in technical process, rotor easily crashes the problem of magnet steel.
