Abstract
The utility model relates to an AC electric motor, in particular to a ceiling fan single-phase AC electric motor stator winding; wherein an upper cover and a lower cover are fixed with a rotor iron core, while the inner circular hole of the rotor iron core is provided with a stator iron core; and a small gap is left between the stator iron core and the rotor iron core; and the center of the stator iron core is fixed with a pendent axis, wherein the pendent axis is fixed with the upper cover and the lower cover through a bearing; while the outer circular surface of the stator iron core is provided with a plurality of lower close slots; wherein the axes side of the lower close slot is provided with a stator slot; and the stator slot is provided with a winding coil, wherein the winding coil ring number is less than one second of the gross stator slot number, namely three or more to a whole stator slot of a main winding or auxiliary winding. The utility model has the advantages that the winding coil off-coil is convenient, and the coil ring serial welding volume is small, and the off-coil time is short, as well as the manufacture and maintenance cost are quite low.
Description
(1), technical field
The utility model relates to alternating current motor, particularly the stator winding of ceiling fan single-phase AC motor.
(2), background technology
At present one of the ceiling fan single-phase AC motor winding coil that uses line in two adjacent stator slots, especially small power motor, because winding coil equals half of groove number or groove number to number, the girth of bundle of lines is less, when rolling off the production line by narrow following wire casing, very inconvenience is wasted time and energy, and brings difficulty for manufacturing and maintenance, and bundle of lines series connection welding capacity is big, the technology very complicated so the time of rolling off the production line is long, is made and the maintenance cost height.
(3), summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of alternating current motor, and winding coil rolls off the production line conveniently, and bundle of lines series connection welding capacity is little, connects simply, and the time of rolling off the production line is short, make and maintenance cost low.Keep under the situation of inconvenience at rotating speed and moment, the effect several times improve,
The technical scheme in the invention for solving the technical problem is: on, under cover the internal fixation rotor core, in the interior cylindrical hole of rotor core stator core is arranged, little gap is arranged between stator core and the rotor core, so that the two can relatively rotate, stator core center fixation hanging axis, hanging axis is by bearing and last, following cover is fixing, uniform wire casing down on the external cylindrical surface of stator core, the center axis of following wire casing is a stator slot, winding coil is arranged in the stator slot, described winding coil number less than 1/2nd total number of stator slots, promptly one the stator slot of following three or three above main windings or auxiliary winding of line.
Described winding coil is 8 word twisted shapes.
Described winding coil is the snake type.
Because bundle of lines quantity reduces, it is big that the girth of bundle of lines becomes, the convenience that rolls off the production line, and coiling is fast, and bundle of lines series connection welding capacity is little, and the time of rolling off the production line is short, and manufacturing and maintenance cost are low.
(4), description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model cutaway view;
Fig. 2 is the utility model winding coil expanded view first embodiment;
Fig. 3 is the utility model winding coil expanded view second embodiment.
(5), embodiment
Upper and lower cover 2,6 internal fixation rotor cores 5 as shown in Figure 1, have stator core 4 in the interior cylindrical hole of rotor core 5, between stator core 4 and the rotor core 5 little gap are arranged, so that the two can relatively rotate.Stator core 4 center fixation hanging axises 1, hanging axis 1 is fixing by bearing and upper and lower cover 2,6.Wire casing 7,8 under the uniform apart major-minor winding on the external cylindrical surface of stator core 4, the center axis of wire casing 7,8 is respectively major-minor winding stator slot under the major-minor winding.Main winding 3 is arranged in the main winding stator slot, auxiliary winding coil 9 is arranged in the auxiliary winding stator slot.Described major-minor winding coil 3,9 is made up of 2 lines respectively, and promptly one the stator slot of following three above main windings of line or auxiliary winding.Described major-minor winding coil 3,9 is 8 word twisted shapes, as shown in Figure 2.Described major-minor magnetic winding 3,9 is the snake type, as shown in Figure 3.Described whole motor winding coil 3,9 number minimum be 2.Described structure line number and major-minor winding coil 3,9 shapes can be used for ceiling fan motor, also can be used for the single-phase AC motor of other form.
Claims (4)
