Problems solved by technology
The asymmetrical magnetomotive force is added to the symmetrical magnetic circuit, resulting in an uneven distribution of the magnetic flux on the iron core, which can easily cause some iron cores to be saturated, while the utilization rate of the other part of the iron core is very low, which will inevitably lead to low motor efficiency and poor core material. waste of

Embodiment Construction
[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0026] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or there may be an intervening element at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.
[0027] It should also be noted that the orientation terms such as left, right, up, and down in this embodiment are only relative concepts or refer to the normal use state of the product, and should not be regarded as limiti...

The invention is suitable for the electrical field of motors and discloses a stator core punching sheet, a motor stator core and a motor. The above stator core punching sheet comprises four first slot groups and four second slot groups which are alternatively and circumferentially distributed. The second slot groups and the first slot groups are symmetrically arranged. Each first slot group contains a first slot position, a second slot position, a third slot position and a fourth slot position. The slot positions and adjacent slog groups are respectively isolated from each other by tooth parts of the same width. The depth of the first slot position is less than the depth of the second slot position. The depth of the second slot position is less than the depth of the third slot position. The depth of the third slot position is less than or equal to the depth of the fourth slot position. The above motor stator core comprises at least two of the above stator core punching sheets. The above motor comprises an end cap and the above stator core punching sheet. According to the stator core punching sheet, the motor stator core and the motor provided by the invention, utilization rate of an iron core is raised, main and auxiliary magnetic circuit distribution is reasonable, and the motor has high efficiency and low cost.
Description
technical field [0001] The invention belongs to the technical field of electric motors, and in particular relates to a stator core punching sheet, a motor stator core and a motor. Background technique [0002] In the prior art, most of the stator punches of the inner rotor single-phase asynchronous motor have the same groove shape and are evenly distributed along the circumference, and there are also a small number of special-shaped groove punches. The groove shape is an axisymmetric groove shape, and the groove shape is single. , This kind of punching is mostly copied from the groove structure of the three-phase asynchronous motor, without fully considering the magnetic circuit characteristics of the single-phase asynchronous motor. In the prior art, the single-phase asynchronous motor using this type of stamping has a symmetrical main-phase and auxiliary-phase magnetic circuits and the same reluctance. When the motor is rated to work, its main and auxiliary phase magnetom...
