One of important content.Motor is the widely used electrical equipment of national economy every profession and trade, and usage amount is big, long operational time,
It is the emphasis of energy-conservation.Therefore, how further to improve the rated efficiency of threephase asynchronous and power factor is this area skill
The problem of art personnel concern.
The content of the invention
The utility model purpose is to provide a kind of Double shaft-extension asynchronous starting permanent magnet synchronous motor.
To achieve the above object, the utility model takes following technical proposals：
Double shaft-extension asynchronous starting permanent magnet synchronous motor described in the utility model, including the motor that stator and rotor are formed
Body, the armature spindle both ends of the rotor are extended outside the forward flange and rear flange of the motor body respectively；Stator iron
Core uses uses built-in radial formula magnetic structure, rotor core with Y2 series asynchronous motor identical peariform slots, rotor core
Rotor shaft hatch is symmetrical with punching and offers four inverted trapezoidal jet-beddings, magnet steel is fitted with respectively in each inverted trapezoidal jet-bedding,
The magnet steel opposite polarity in adjacent inverted trapezoidal jet-bedding；Described between each inverted trapezoidal jet-bedding and the rotor shaft hatch
On rotor iron core lamination, the arc jet-bedding concentric with rotor shaft hatch is offered respectively.
The rearward end of the armature spindle is extended outside the fan guard of the motor body, is turned in the fan guard
Fixed cover is equipped with fan on sub- axle.
The utility model advantage is that the Double shaft-extension asynchronous starting three-phase permanent magnet synchronous motor rated efficiency reaches as high as
96.3%, and in load factor 20%~140%, efficiency high power factor 0.99, can substitute industrial processes use up to more than 92%
Normal asynchronous.Motor exports for Double shaft-extension, and armature spindle both ends export identical torque, starting torque by shaft coupling
Greatly, noise is low, with small vibration, reliability is high, and can be applied to industrial crane, pump, transporter, mixer etc. needs the biography of double load
In dynamic system.

The motor body that son 2 and rotor 3 are formed, the preceding method of the motor body is extended at the both ends of armature spindle 4 of the rotor 3 respectively
Outside orchid 5 and rear flange 6 and fan guard 7, fixed cover is equipped with fan 8 on the armature spindle 4 in the fan guard 7.
The use of stator core 9 and Y2 series asynchronous motor identical peariform slots, therefore can be to the asynchronous electricity of common Y2 series
Motivation stator core is recycled.Rotor core uses built-in radial formula magnetic structure, is symmetrical with rotor iron core lamination
Rotor shaft hatch 10 offers four inverted trapezoidal jet-beddings, and magnet steel 11 is fitted with respectively in each inverted trapezoidal jet-bedding, each ladder
The magnet steel 11 in shape jet-bedding is formed by four pieces, and this structure is applicable very much for high power motor, adjacent inverted trapezoidal punching
The opposite polarity of magnet steel 11 in groove；The rotor iron core lamination between each inverted trapezoidal jet-bedding and the rotor shaft hatch 10
Upper to offer the arc jet-bedding 12 concentric with rotor shaft hatch 10 respectively, the arc jet-bedding 12 is used for after alleviating installation armature spindle 4
To the extruding force of inverted trapezoidal jet-bedding, the installation accuracy of guarantee magnet steel 11.
