Abstract
An asynchronous motor with squirrel-cage rotor is composed of stator and rotor that is divided into two coaxial parts connected serially with a certain included angle between them. The conducting strips in rotor are wrapped by insulating layer and Each silicon steel sheet insulated from other. Said asynchronous motor can feed part or all of reactive power back to power supply system for higher power factor, so making it near the inductive motor. Stepless speed regulation and fixing speed at any value can be realized.
Description
The invention belongs to three-phase or single phase poaer supply asynchronous machine, relate to a kind of improvement of rotary or orthoscopic cage rotor asynchronous machine.

Squirrel-cage rotor asynchronous motor of the present invention comprises stator and rotor, and its rotor is divided into two parts coaxial and serial connection, the coaxial relatively certain angle that turns over of two parts rotor, the sliver outsourcing insulation in the rotor, the sheet intercropping insulation processing of silicon steel sheet.
Its speed governing means of squirrel-cage rotor asynchronous motor of the present invention can be main winding and the speed governing windings that the stator winding is divided into coaxial arrangement, the core slots number of two parts winding is identical or slightly different, the corresponding two parts rotor of difference, two stator windings insert power supply with head end and tail end respectively, and embodiment is: main winding directly inserts power supply; The speed governing winding can directly insert power supply, also can insert power supply by step-down transformer, and perhaps the head end with the speed governing winding is connected on the main winding tail end.According to the needs that motor speed is set, the iron core of speed governing winding can be fixed main winding corresponding turning an angle (electrical degree) unshakable in one's determination, promptly constitute any constant-seed motor.
The invention has the advantages that, because the change of two parts rotor relative angle, make that the phase place of induced potential changes in the rotor, influence the electric current in the stator winding, thereby can keep High Power Factor to power-supply system feedback fraction or whole reactive powers, make squirrel-cage rotor asynchronous motor of the present invention can by induction motors near or reach the capacitive motor, and then make electrical network reduce the output of reactive power, improved the capacity of electrical network.In addition, its speed governing winding influences rotor electromotive force by introducing back-emf, can realize stepless speed regulation or any constant speed, and the feedback slip power, improved electric efficiency, it is simple to adopt the speed governing winding to carry out speed regulating structure simultaneously, cost is low, and withstand voltage height, applied range.
