A motor includes a stator assembly, a rotor assembly, and a terminal assembly. The stator assembly includes a stator core and a winding wound onto the stator core. The winding includes an input end and an output end. The rotor assembly includes a rotor shaft extending along a direction of a first straight line. The terminal assembly is configured to connect or fix the input end and the output end. The stator core includes first-type laminations. Each of the first-type laminations is provided with connection arms and a special-shaped portion. The special-shaped portions are configured to form an access slot which is configured to connect the terminal assembly when the first-type laminations are stacked along a direction parallel to the first straight line. The access slot is disposed on an outer sidewall of the stator core.

The embodiments of the present disclosure provide a method for an image simulation generation based on a near-field simulation of a computational electromagnetic field, the method comprising: constructing a simulated three-dimensional model based on model parameters; constructing a simulated Kohler illumination model based on a light source parameter; using a degree of similarity change in a synthesized image under incremental aperture diaphragm sampling points as a criterion for approximate convergence of the simulation to determine a count of samples to be used for a balancing combination of simulation cost and accuracy; an optical simulation is performed based on the simulated three-dimensional model and the simulated Kohler illumination model, and a far-field electromagnetic field distribution data is obtained to obtain a simulated image by synthesizing the image. In the generation of a large count of simulated images on the basis of pseudo-random defect dataset generation may be further realized, in the acquisition of a large count of datasets, the dataset of defect inspection model may be trained, in order to achieve a direct detection for patterned wafer defective images and solve the problem of difficult access to reference images in a process of patterned wafer defect detection.
