The invention relates to the technical field of motor manufacturing, in particular to a high-performance motor iron core processing equipment and processing method. The processing equipment includes a coiling device, a leveling device, a coating thickness measuring device and a stamping device. In the processing equipment provided by the present invention, the steel strip coiled on the coiling device can be released automatically by its own tension and elasticity, and the steel strip after being released is leveled by the leveling device to become smoother, which is beneficial to subsequent processing. The coating thickness measuring device can coat the upper and lower surfaces of the steel strip with paint and can detect the thickness of the steel strip and the thickness of the paint on the steel strip, and can squeeze out excess paint and water on the steel strip. The stamping device can stamp the steel strip into steel sheets of a certain size, heat and solidify the steel sheets, and automatically stack and transport the steel sheets. The entire processing equipment can run automatically, with high processing efficiency, no need for manual labor, which can save labor costs, facilitate the realization of automatic production, and better adapt to the needs of modern processing.
