Embodiment
Below with reference to accompanying drawing, the utility model is described in detail：
With reference to shown in Fig. 1 to Fig. 4, a kind of high slippage squirrel cage asynchronous motor of modified disclosed in the present embodiment, including it is fixed
Son 1, rotor core 2, rotating shaft 3, rotating shaft 3 pass through the axis of rotor core 2, and are fixedly and coaxially connected with rotor core 2, stator 1
Coaxial package in the outside of rotor core 2, the first-class spacing annular array of the interior edge of stator 1 have several axially through stator slot 4, turn
The first-class spacing annular array in outer of sub- iron core 2 have several axially through rotor slot 5, rotor slot 5 be interior narrow outer width depth
Groove blade type, be additionally provided with rotor core 2 equidistant annular array several axially through magnet steel through hole, magnet steel through hole position
On the inside of rotor slot, magnet steel 6 is provided with magnet steel through hole.
As preferable, 6 magnet steel, magnet thickness 4mm are internally embedded in rotor core 2, equidistant annular array is set,
So not only save material but also maintain enough magnetic pulls.
Specifically, magnet steel 6 is the permanent magnet of strip, and its section vertical with rotor core is with the axis of rotor core
For one section of circular arc in the center of circle.
Specifically, the edge that inwardly projecting section is triangle is provided with the opening both sides of rotor slot 5.
Common asynchronous machine is slower than the rotating speed of rotating excitation field due to the rotating speed of rotor core, by rotating excitation field cutting rotor
Winding, so as to produce induced-current in rotor windings, the rotor conductor of current-carrying will produce in the presence of stator rotating excitation field
Electromagnetic force, so as to form electromagnetic torque on machine shaft, due to revolutional slip be present, in motor driven large inertia load operation mistake
Cheng Zhong, excessive revolutional slip can reduce the rotating speed of asynchronous machine, and reduce electric efficiency.
On the rotor core of squirrel cage asynchronous motor after embedded magnet steel, because magnet steel band is magnetic, it will in rotor iron
Extra magnetic pull is produced on core, less revolutional slip, the squirrel-cage asynchronism of embedded magnet steel are only needed in the case of identical load
Motor will be lower than the squirrel cage asynchronous motor revolutional slip of no embedded magnet steel, and rotating speed is fast, efficiency high.
The rotating speed of common squirrel cage asynchronous motor under experimental conditions is about 550r/ it can be seen from Fig. 3 and Fig. 4
Min, and same squirrel cage asynchronous motor rotor core be embedded in magnet steel after, the rotating speed under identical experiment condition is promoted to
900r/min。
The utility model uses rotor slot as shown in Figure 5, and rotor slot is deep trouth blade type groove, and opening both sides have inside
Prominent outer, using the self-running characteristic of asynchronous machine, and the magnet steel of arc is embedded on rotor core, can allow motor
Very high starting torque is kept, while maintains the essence of asynchronous machine in itself again.
Above example is the exemplary illustration to this patent, does not limit its protection domain, people in the art
Member can also be changed to its part, as long as no the Spirit Essence beyond this patent, all in the protection domain of this patent.
