Stepping motor capable of preventing eccentric operation

Abstract

The invention provides a stepping motor capable of preventing eccentric operation. The stepping motor comprises a stepping motor main body, a cover plate and a balancing device, and can solve the problems that the existing stepping motor is easy to generate resonance when being incorrectly controlled, and is difficult to operate to a higher rotating speed and obtain a larger torque; when an outputshaft of the stepping motor bears a carrier with a certain weight and is driven to rotate, the stepping motor often needs to be started and stopped in the working process; in order to solve the problems that the output shaft is difficult to keep balanced when bearing an object, and the output shaft eccentricity of a carrier borne by the output shaft is caused in the rotating process, so that theoutput shaft cannot operate better, the stepping motor can keep a stable function in the moving process of the stepping motor; the stepping motor has the advantages that stability of the stepping motor in the moving process can be kept, resonance of the stepping motor is reduced; and meanwhile the stepping motor guarantees that the output shaft cannot be eccentric when the output shaft bears objects of different weights.

Description

technical field [0001] The invention relates to a stepping motor, in particular to a stepping motor capable of preventing eccentric operation. Background technique [0002] Stepper motors are also called steppers, which use the principle of electromagnetism to convert electrical energy into mechanical energy. People began to use this type of motor as early as the 1920s. With the growing popularity of embedded systems such as printers, disk drives, toys, wipers, vibrating pagers, robotic arms, and video recorders, the use of stepper motors has exploded. Whether in industry, military, medical, automotive, or entertainment, stepper motors are used whenever an object needs to be moved from one location to another. [0003] Stepper motors have excellent start-stop and reverse response; at the same time, they have the greatest torque when they stop (when the windings are excited); therefore, the use of stepper motors is also increasing rapidly, but currently stepper motors are no...

Problems solved by technology

[0005] In order to solve the above problems, the present invention provides a stepper motor that can prevent eccentric operation, which can solve the problem that the current stepper motor is prone to resonance when it is not controlled properly, and it is difficult to run to a higher speed and obtain a larger torque at the same time; When the output shaft of the stepper motor is driven by a carrier with a certain weight to rotate, because the stepper motor often needs to be started and stopped, it cannot obtain a large speed, which makes it difficult for the output shaft to maintain balance when carrying objects. In the process of rotation, the carrier it carries is eccentric, which makes it unable to run better. It can realize the function of keeping the stepper motor stable during its movement; it can keep the stepper motor stable during its movement and reduce its resonance. , and at the same time ensure that the output shaft will not be eccentric when it is carrying objects of different weights.
