Description

A kind of durable electric machine structure
Technical field
The utility model is related to a kind of durable electric machine structures.
Background technology
Currently, existing electric machine is mainly to judge motor by the way that whether detection motor working current is more than preset value It is no to be hampered, in this way, it needs to preset relatively threshold value in control circuit board, when the setting of the comparison threshold value of setting is excessive, can lead Cause be hampered protection reacted slowly, when setting comparison threshold value setting it is too small when, it may appear that normal resistance is mistaken for the resistance that is hampered The case where occur, setting is inconvenient, is not easy to the protection that is hampered well.
Utility model content
The utility model overcomes the deficiency of above-mentioned technology, provides a kind of durable electric machine structure, and the practicality is good.
To achieve the above object, the utility model uses following technical proposal:
A kind of durable electric machine structure includes pedestal 11, upper cover body 12, the electromagnetic coil 2 being arranged on the pedestal 11 And it is rotatably installed in the rotor assembly 3 driven by the electromagnetic coil 2 between the pedestal 11 and upper cover body 12, the rotor Component 3 includes the armature spindle 31 being rotatably installed between the pedestal 11 and upper cover body 12, and the upside of the armature spindle 31 is set There are the first magnet rotor 32 rotated synchronously with armature spindle 31 and downside to be rotatablely equipped with second driven by the electromagnetic coil 2 Magnet rotor 33, second magnet rotor, 33 upside are equipped with the magnetic hysteresis alloy circle positioned at first magnet rotor, 32 outside 34, power output shaft of the armature spindle 31 as motor.
A kind of durable electric machine structure as described above, the electromagnetic coil 2 include for driving the rotor assembly 3 to rotate forward Positive switch coil 21 and for drive the rotor assembly 3 invert reversion coil 22, the positive switch coil 21 and reversion coil 22 be setting up and down.
A kind of durable electric machine structure as described above, 31 lower end of the armature spindle are stretched out outside the pedestal 11 and are equipped with defeated Go out gear 4.
Compared with prior art, the utility model has the beneficial effects that:
1, structure is simple and easy to implement for this case, and when work, second magnet rotor is driven by the electromagnetic coil and rotated, The magnetic hysteresis alloy circle is rotated synchronously with second magnet rotor, between first magnet rotor and the magnetic hysteresis alloy circle It is attractive, in this way, when the magnetic hysteresis alloy circle is rotated synchronously with second magnet rotor under the action of attraction its First magnet rotor is driven to rotate, armature spindle rotates synchronously and output motor power with the first magnet rotor, when described turn Sub- axis be hampered stopping when, second magnet rotor can't be stuck, and second magnet rotor still can be relatively described First magnet rotor rotates and consumes electric energy, is conducive to send out the case where reducing operating current increase suddenly and burn out electromagnetic coil It is raw, it is durable, practicability is good.
2, output gear is stretched out outside the pedestal and be equipped in the armature spindle lower end, in this way, described first magnetic turn Son is located at the armature spindle upper end and the output gear is located at the armature spindle lower end, is conducive to make the first magnet rotor, turn The assembly center of gravity of sub- axis and output gear is located at the armature spindle near middle, be conducive to armature spindle the pedestal with It is rotated between upper cover body.

Fig. 1 is the explosion diagram of this case.
Fig. 2 is the rotor assembly of this case.
Fig. 3 is the explosion diagram of Fig. 2.
Fig. 4 is the perspective representation of this case.
Specific implementation mode
The utility model feature and other correlated characteristics are described in further detail by the following examples, in order to same The understanding of industry technology personnel:
As Figure 1-Figure 4, a kind of durable electric machine structure includes pedestal 11, upper cover body 12, is arranged in the pedestal 11 On electromagnetic coil 2 and be rotatably installed in the rotor driven by the electromagnetic coil 2 between the pedestal 11 and upper cover body 12 Component 3, the rotor assembly 3 include the armature spindle 31 being rotatably installed between the pedestal 11 and upper cover body 12, described turn The upside of sub- axis 31 is equipped with the first magnet rotor 32 rotated synchronously with armature spindle 31 and downside is rotatablely equipped with by the electromagnetism The second magnet rotor 33 that coil 2 drives, second magnet rotor, 33 upside are equipped with positioned at first magnet rotor 32 The magnetic hysteresis alloy circle 34 in outside, power output shaft of the armature spindle 31 as motor.
As described above, structure is simple and easy to implement for this case, when work, second magnet rotor 33 is by the electromagnetic coil 2 Driving and rotate, the magnetic hysteresis alloy circle 34 is rotated synchronously with second magnet rotor 33, first magnet rotor 32 and It is attractive between the magnetic hysteresis alloy circle 34, in this way, the magnetic hysteresis alloy circle 34 is synchronized with second magnet rotor 33 It drives first magnet rotor 32 to rotate under the action of attraction when rotation, and armature spindle 31 is same with the first magnet rotor 32 Step rotates and output motor power, and when the armature spindle 31 is hampered stopping, second magnet rotor 33 can't be stuck, Second magnet rotor 33 can still rotate relative to first magnet rotor 32 and consume electric energy, be conducive to reduce work Electric current increases suddenly and the case where burning out electromagnetic coil occurs, durable, practicability is good.
As described above, when it is implemented, the electromagnetic coil 2 includes for driving the rotor assembly 3 to rotate forward just Switch coil 21 and for drive the rotor assembly 3 invert reversion coil 22, the positive switch coil 21 and reversion coil 22 be It is setting up and down.
As described above, when it is implemented, 31 lower end of the armature spindle is stretched out outside the pedestal 11 and is equipped with output gear 4, in this way, first magnet rotor 32 is located at 31 upper end of the armature spindle and the output gear 4 is located at the armature spindle 31 Lower end is conducive to make the assembly center of gravity of the first magnet rotor 32, armature spindle 31 and output gear 4 to be located at the armature spindle 31 near middles are conducive to armature spindle 31 and are rotated between the pedestal 11 and upper cover body 12.
As described above, this case protection is a kind of durable electric machine structure, all technologies same or similar with this case structure Scheme should all be shown as falling into the protection domain of this case.
