Description
A kind of single-phase capacitor running tap speed-regulating asynchronous motor belongs to the AC asynchronous motor technical field.Be suitable for household appliances and make buncher usefulness.
Existing single-phase tap adjustable-speed motor, its speed governing winding and auxiliary winding all are (as the L-2 types) in the same groove that embeds in motor stator, and do not add any insulant between their ends and be separated by, like this, just making has a plurality of contact-making surfaces between speed governing winding and the auxiliary winding.Motor is when slow shelves state operation, and the speed governing winding has formed two different circuit with auxiliary winding, short circuit between winding takes place easily and makes motor can not continue operation.Special tectonic owing to this motor windings makes technique for coiling and wiring technology comparatively complicated in addition.
The purpose of this utility model provides and a kind ofly can overcome above-mentioned shortcoming, can realize the single-phase capacitor running tap speed-regulating asynchronous motor of speed governing.
The single speed permanent split capacitor motor designing technique design routinely of the relevant design parameter of each winding of the utility model capacitor operating tap adjustable-speed motor.The utility model single-phase capacitor running tap speed-regulating asynchronous motor comprises front housing (1), back cabinet (2), fore bearing (3) and rear bearing (4), cage rotor (5), rotating shaft (6), motor stator (7) is loaded on main winding (8) and auxiliary winding (9) in the stator slot, working capacitor C and change over switch K.Main winding in the stator winding and auxiliary winding are individual layer chain type winding.Main winding has end connector A and a, and auxiliary winding has end connector B and b, also has centre tap D, and tap D draws with being connected in series on the line of the 4th coil at auxiliary winding the 3rd, also can draw tap again at the turn-to-turn in the suitable coil.Receive power supply again with the main winding end A and after connecing behind the auxiliary winding termination B serial connection capacitor C.Main winding end connector a and auxiliary winding termination b and connect after lead-out wire E end and tap D end, pass through change over switch K respectively and be connected with external power supply.When change over switch K was connected with the E end, motor was the top gear running status, and main winding is made the work winding, and auxiliary winding is made the starting winding, and the work that participates in together is the same with conventional single speed capacitor-operated motor.Motor is the low or first gear running status when change over switch K is connected with the D end, at this moment, the 4th coil of auxiliary winding increases the main winding number of turn with the synthetic main winding (each coil turn of auxiliary winding is identical) of main winding series connection, reach the purpose that reduces rotating speed, its excess-three coil makes to start winding, the situation of this moment is actually " separates " placement to effective turn of using do speed governing and startup winding, and its speed governing effect is better than other tap methods, has also avoided the contingent short circuit phenomenon of contact-making surface between group.Main winding in the utility model stator winding is installed in the different grooves with auxiliary winding, and is added with insulant keeps apart between the end that main winding and auxiliary winding are drawn.The utility model is applicable to that household appliances (as fan motor, air-conditioning adjustable-speed motor, fume exhauster motor etc.) make adjustable-speed motor and use.
The utility model has the advantages that and avoided motor to be installed in the short circuit that may cause in the same stator slot between winding, improve the safe and reliable of motor operation, improve the quality of products and the life-span because of speed governing winding and auxiliary winding.In addition, the utility model tie lines is simple, technique for coiling and wiring work simplification.
