Embodiment

Now in conjunction with Figure of description, describe embodiment of the present utility model in detail:

As shown be the stator winding syndeton of single-phase speed regulating motor, stator winding comprises main winding and auxiliary winding A, and main winding is made up of body winding M and speed governing winding M0 cooperation, body winding M, speed governing winding M0, auxiliary winding A is made up of four coils connected in series respectively, the joint construction of each coil and syndeton are: 16 line embedding grooves that stator is equipped with form eight coil its rabbet position, body winding M and auxiliary winding A has four coils to be sequentially connected in series formation respectively, four coils of body winding M and four coils of auxiliary winding A are spaced setting according to this, the its rabbet position of four coils of body winding M is N1 according to this, S1, N2, S2, containing two scarfing slots between two scarfing slots of an interlocking coil, four coils of speed governing winding M0 are rabbeted in identical line embedding groove with four coils of body winding M, and four of speed governing winding coils are according to the first coil N1, tertiary coil N2, second coil S1, the sequential series of the 4th coil S2, arrange speed governing tap between tertiary coil N2 and the second coil S1 to form mid ranger and to go between M, screening pole principle speed governing winding M0 is utilized to be divided into speed governing winding M01, speed governing winding M02 two parts, body winding M, syndeton between speed governing winding M0, auxiliary winding A are: the initiating terminal of auxiliary winding A to be connected after an electric capacity with the initiating terminal of body winding M and head, this and head forms common port COM in order to be connected with one end of power supply, the initiating terminal of the ending end of auxiliary winding A, the ending end of body winding M and speed governing winding MO connects and composes the go between ending end of H, speed governing winding M0 of top gear and forms low or first gear and to go between L, the other end that top gear lead-in wire H, mid ranger lead-in wire M and low or first gear go between respectively by control switch power supply in L is connected, in speed governing operation process, by the wherein way control switch that closed top gear lead-in wire H, mid ranger lead-in wire M and low or first gear go between in L and power source connection circuit, motor operates in corresponding speed threshold, namely power supply one end and common port COM keep being connected, the other end and top gear one of going between that H, mid ranger go between that M and low or first gear go between in L goes between and is connected, the speed threshold that the corresponding company of operating in of motor goes between.

Application the utility model, in the rule process of stator winding, because main winding only has winding body M and speed governing winding M0 to form, with two speed governing windings of the prior art, decrease one coil winding program, man-hour can be saved, enhance productivity, and in use, during mid ranger, use speed governing winding M01, namely use two coils of speed governing winding M0, and speed governing winding M01, speed governing winding M02 access when low or first gear uses, namely speed governing winding M0 entirety is access in main winding.
