Description
Technical field
The present invention relates to electric machine structure, particularly a kind of single-phase pole-changing double speed asynchronous machine.
Background technology
Three-phase change pole double speed asynchronous machine is made up of casing, stator, rotor, main shaft, terminal box at present.Stator winding is double-layer lap formula winding, the V1 arranging on winding, V2, U1, U2, W1, W2 the end of a thread respectively with terminal box in V1, the V2, U1, U2, W1, the W2 binding post connection that arrange.Three phase mains respectively with V1, U1, W1 binding post connection, and V2, U2, W2 binding post are two states, one is three pole interconnections, one is that three posts do not connect, thus double-layer lap formula winding is different circuit states, motor is two kinds of different rotating speeds.The speed that can realize AC induction motor by change electric moter voltage frequency, number of pole-pairs, revolutional slip regulates.When supply frequency one timing, by changing the magnetic pole logarithm of motor stator winding, just can make the rotating speed of motor change, because not being reaches speed governing object by pressure regulation means, therefore this electric moter voltage frequency fluctuation scope is little, difference variation is also little, and control circuit has advantages of function admirable, meets the required design parameter of motor.Can, according to the different designs of environment for use, there be constant-power speed regulation and speed regulation by constant torque, belong to pole change induction motor speed governing.
The stator double-winding motor speed change of monophase machine is except adopting variable-frequency and variable-speed control circuit at present, the general transformation speed Control circuit (comprising tap speed change) that adopts, transformation variable speed electric motors, particularly turns round in the time of low speed, and temperature rise efficiency is low, and in the time of voltage ripple of power network, rotation speed change is large.This motor is divided into again four utmost point motor and 6-pole motors.
Chinese patent ZL200620040735.8 discloses " a kind of single-phase variable polar, double-speed asynchrnous motor ", its scheme is that stator winding is four utmost points, sextupole double winding, in each winding, be connected in series respectively a C1 or C2 electric capacity, connect respectively a winding by diverter switch, form and make it pole-changing windings.Its defect is: doublewound line embedding groove list groove is wanted embedding four lines, and flute profile will expand.Wire insertion technology operation easier strengthens.
Summary of the invention
The object of the invention is to overcome above-mentioned defect, a kind of single-phase pole-changing double speed asynchronous machine is provided.
The solution of the present invention is: comprise casing, stator, rotor, main shaft, terminal box, also comprise C1, C2 electric capacity, it is characterized in that: stator winding and terminal box are double-layer lap formula winding and the terminal box of three-phase change pole double speed asynchronous machine; In the time that single phase poaer supply is connected with U1, W1 binding post respectively, between U1, W1 binding post, be connected in series C1 electric capacity, be four utmost point speed change state; In the time that single phase poaer supply is connected with U1, W1 binding post respectively, between V1, W2 binding post, be connected in series a capacitor C 2, three pole interconnections between V2, U2, W2 binding post, motor is sextupole speed change state.
The invention has the advantages that: utilize three-phase double-layer lap formula stator winding, silicon steel sheet manufacture simplification, rule operating procedure is simplified, and enhances productivity.
