Embodiment Construction

[0064] A start-stop control method and system for a stepping motor, matching corresponding mathematical models for different loads, and can adjust the coefficients of the mathematical model, meeting the complex load requirements of the stepping motor, correspondingly, making the stepping motor work Higher efficiency and wider application range. During the working process of the stepper motor, adjust the current of the stepper motor according to the working state of the stepper motor, flexibly control the movement of the stepper motor, and reduce the noise and low-frequency vibration of the stepper motor; and according to the state of the stepper motor Adjust the size of the current, because the state of the stepping motor corresponds to the load torque, that is, adjust the size of the current according to the load torque, which can prevent the problem of step loss when the motor torque and load torque are unbalanced.

Abstract

The invention discloses a start and stop control method and a start and stop control system for a stepping motor, for controlling the stepping motor with a load, selecting a mathematic model matched with the load and setting the coefficient of the mathematic model, receiving a control parameter for controlling the operation of the stepping motor, computing the characteristic parameter of the motion trail of the stepping motor according to the mathematic model and the control parameter, generating a drive control signal according to the characteristic parameter of the motion trail, and controlling the stepping motor according to the drive control signal. Through matching the corresponding mathematic model with different loads, the complicated load requirement of the stepping motor is met, the work efficiency of the stepping motor is improved, and the application range of the stepping motor becomes wider. Meanwhile, the invention also discloses a stepping motor, and a start and strop control system for the stepping motor.

Description

technical field [0001] The invention relates to the technical field of motor control, in particular to a start-stop control method of a stepper motor, a start-stop control system of a stepper motor and a stepper motor. Background technique [0002] Stepping motor is a commonly used executive component in automatic control system, and it is one of the key products of mechatronics. It is widely used in various computer-controlled automatic systems. With the development of microelectronics and computer technology, the demand and application of stepping motors are increasing day by day. The outstanding advantage of the stepper motor is that it can achieve speed regulation, fast start and stop, forward and reverse control, etc. by changing the pulse frequency in a wide frequency range, and the open-loop system composed of it is simple, cheap, and very reliable. , so it has a very wide range of applications in many fields. [0003] In order to solve the problems of shortening th...
