Problems solved by technology

[0002] In the traditional automatic electronic control system, the driving of multi-axis motors is usually driven by a separate single driver, which has complex structure, low integration, large electronic control installation area, and low multi-axis synchronization accuracy.
[0003] With the rise of 3C and other industries, the integration of equipment is getting higher and higher, the space for power supply and control installation is getting smaller and smaller, and the requirements for multi-axis synchronization performance are getting higher and higher. As a result, a frame product with integrated multi-axis drives has emerged. The integrated single-switch power supply realizes the power supply of multi-axis motor drivers. Since the output voltage of the power supply in the multi-axis motor driver is large, the design of the integrated single-switch power supply is complicated, and the power supplies of each axis affect each other. When the power supply of one axis appears When the output is overloaded or short-circuited, the entire multi-axis drive will not operate normally, and when the number of drive axes is expanded, the scalability of the power supply is poor and the development cost is high

Abstract

The invention discloses a power supply circuit of a multi-axle motor driver. The power supply circuit comprises a main switching power supply module and at least two secondary switching power supply modules; the output of the main switching power supply module is respectively used as the input of each secondary switching power supply module; the number of the secondary switching power supply modules is equal to the axle number of the multi-axle motor; and the main switching power supply module is used for supplying power to a universal function part of the multi-axis motor driver, and each secondary switching power supply module is used for supplying power to a corresponding inversion IGBT driving module in the multi-axle motor driver. The design of a power supply system of the multi-axledriver is simplified, the design of a power supply of the multi-axle motor driver can be modularized and standardized, and when the number of axles of the motor driver is increased, the power supply can be expanded, replaced and overhauled flexibly and conveniently.
