Sewing machine rotating speed control method, sewing machine and storage medium

The invention relates to a sewing machine rotating speed control method, a sewing machine and a storage medium, and the method comprises the steps that the proportion of a time parameter of the sewing machine running at a first rotating speed in the running process to a total running time parameter is obtained, the first rotating speed is not lower than a first threshold value, and the time parameter comprises running duration or the number of running stages; when the proportion is not lower than the second threshold value, the upper limit of the rotating speed of the sewing machine is increased, and the problem that the sewing efficiency of the sewing machine is low under the condition that the highest rotating speed of the sewing machine cannot be matched with the skill proficiency degree of the user in the related technology is solved. 本申请涉及一种缝纫机转速控制方法、缝纫机及存储介质，其中，该方法通过获取缝纫机在运行过程中以第一转速运行的时间参数占总运行时间参数的比例，其中，第一转速不低于第一阈值，时间参数包括运行时长或者运行阶段数目；在比例不低于第二阈值的情况下，调高缝纫机的转速上限，解决了相关技术中在缝纫机的最高转速无法与用户的技能熟练度不匹配的情况下，缝纫机的缝制效率
