Technical field
The utility model relates to a kind of line-start permanent magnetic synchronous motor, belongs to technical field of motors.
Technical background
Existing its rotor core of line-start permanent magnetic synchronous motor has two kinds substantially, and a kind of is to be made by low-carbon steel material integral body or polylith splicing, is called for short the solid type rotor, and its advantage is that starting torque is big, and shortcoming is that the high order harmonic component loss is big when synchronous operation, efficient is low; Another kind is that silicon steel sheet is repeatedly made, and is called for short laminate patch type rotor, and the high order harmonic component loss was little when its advantage was synchronous operation, efficient is higher, and shortcoming is that starting torque is less.
Summary of the invention
The purpose of this utility model is to draw the advantage of prior art, overcome its shortcoming, and the line-start permanent magnetic synchronous motor that a kind of starting performance is good, operational efficiency is high is provided.
The purpose of this utility model realizes by following technique measures.A kind of line-start permanent magnetic synchronous motor is made up of stator and rotor, and its special character is outer iron core that rotor core is repeatedly made by silicon steel sheet and is made up of the interior iron core that mild steel is made that interior iron core is fixed on the motor shaft, in outer iron core is fixed on the iron core.
Described rotor outer iron core is an integral circular shape, in have mouse cage shape to annotate the aluminium sliver, the number of sliver is the even-multiple of motor pole number.
Stud with permanent magnet in the iron core in the described rotor, permanent magnet is when radially being bumped into mode, each magnetic pole middle of interior iron core has closed air gap groove, the width of groove is identical with the width that is bumped into permanent magnet, when permanent magnet adopted cross section to be bumped into mode for W shape, the top of its W shape groove center just in time was on the cylindrical of interior iron core.
The utility model compared with prior art its advantage is: (1) is owing to adopted the compound rotor core structure of being made up of silicon steel sheet and mild steel, compare with the solid type rotor and to have reduced magnetic field high order harmonic component loss effectively, improved electric efficiency, comparing with laminate patch type rotor has bigger starting torque.(2) owing to be provided with closed air gap groove or W shape permanent magnet trough in the rotor in the iron core and match, increased the quadrature-axis reluctance of motor effectively, improved the starting performance of motor with sliver groove on the outer iron core.
