Embodiment Construction

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0039] Such as figure 1 As shown, a servo motor voltage control method includes the following steps:

[0040] S1: Collect the current working voltage of the servo motor through the controller; when the collected working voltage is within the set range, repeat step S1, and when the collected working voltage exceeds the set range, perform step S2;

[0041] S2: Use a phase-shifted full-bridge circuit to adjust the input voltage of the servo motor, and repeat step S1 after each adjustment is completed;

[0042] Among them, the controller keeps the preset duration of power-on of the transformer in the phase-shifted full-bridge circuit unchanged, and realizes the adjustme...

Abstract

The invention relates to the technical field of servo motor control, in particular to a servo motor voltage control method. The method comprises the following steps: S1, collecting the current working voltage of a servo motor through a controller, repeatedly executing the S1 when the collected working voltage is within a set range,and executing S2 when the collected working voltage exceeds the set range; and S2, adjusting the input voltage of the servo motor by adopting a phase-shifted full-bridge circuit, and repeating the S1 after each adjustment is completed. The controller keeps the preset duration of power-on of a transformer in the phase-shifted full-bridge circuit each time unchanged, and the phase-shifted full-bridge circuit controls the change of the signal frequency to realize the adjustment of the duty ratio of the preset duration of power-on of the transformer, thereby realizing the adjustment of the working voltage. According to the method, the whole working process of the servo motor can be timely and effectively controlled, a frequency conversion control mode is adopted, the stability of output voltage is improved, and the service life of the motor is prolonged.

Description

technical field [0001] The invention relates to the technical field of servo motor control, in particular to a servo motor voltage control method. Background technique [0002] During the working process of the servo motor, a more stable input voltage can improve the service life of the servo motor and obtain a more stable working state; however, in the actual working process, due to the fluctuation of the power supply itself, the servo motor There will inevitably be fluctuations in the working voltage, which will cause irreversible effects on the servo motor during long-term use. [0003] In view of the above problems, based on years of rich practical experience and professional knowledge in the engineering application of such products, and with the application of academic theory, the designer actively conducts research and innovation in order to design a servo motor voltage control method. Contents of the invention [0004] The invention provides a servo motor voltage c...
