Problems solved by technology

However, such a control method needs to reduce the current speed to a certain value before intervening in the control, and when the motor is continuously overloaded, even if the speed loop control parameters are strengthened, the actual speed will not immediately return to the desired speed, but will still There is a descent and then a pull back, so the effect is limited

Abstract

The invention discloses a motor control method of a sewing machine. The mechanical angle of the motor when the rotational speed is the lowest in the process of turning a circle is taken as the mechanical angle B of the motor; in the process of sewing, when the angle of the motor is A‑M, adjust the parameters of the speed loop in the motor control system to increase the motor When the motor angle is B-N, restore the parameters of the speed loop to the default values; among them, 0<M<A, 0<N<B, and B-N>A-M. By applying the solution of the present application, the rotation speed of the motor can be made more stable when the sewing machine sews thick materials, thereby improving the sewing production efficiency and sewing effect, and improving user experience. The present application also provides a motor control system, equipment and storage medium of the sewing machine, which have corresponding effects.

Description

technical field [0001] The invention relates to the technical field of sewing machines, in particular to a motor control method, system, device and storage medium of a sewing machine. Background technique [0002] With the development of science and technology, users have higher and higher requirements for product performance. For sewing machines, users have higher and higher requirements for their ability to sew thick materials. [0003] When the sewing machine sews thick materials, it is equivalent to loading a heavy load on the motor of the sewing machine. When the machine is puncturing thick materials, the load is the largest at this time, and the actual speed of the motor will drop immediately. Generally, low speed is used when sewing thick materials. Under such low speed and heavy load conditions, the speed feedback of the motor lags behind, the speed control response is slow, and the running speed of the motor will fluctuate greatly, that is, after the speed of the mo...
