AI Technical Summary

⚠Technical Problem

In traditional servo drives, the power block and other functional circuits are integrated on the same PCB board, resulting in poor reusability and high costs for maintenance and customized design.

⚗Method used

The modular design allows for the independent packaging of the power board, heat sink, IPM module, power input port, and control input/output port, which are then fixed to the mounting bracket using a fixing device, enabling individual maintenance and customized design.

🎯Benefits of technology

It improves the structural strength and reusability of the servo drive, reduces design and maintenance costs, and allows for the replacement of different models of IPM modules according to different motor requirements.

Abstract

The application discloses a modular servo driver power unit module, which comprises a power board (20), a plurality of IPM modules (204) are integrated in the middle area of the power board (20), and a power input port (203), a control input port (202) and a control output port (201) are integrated in the edge area of the power board (20); the power input port (203) is used for receiving external power; the control input port (202) is used for acquiring a control signal sent by an external device; and the control output port (201) is used for sending a driving signal to an external motor. The power board (20) is fixedly arranged on a mounting bracket (10), and a radiator (30) is connected with the middle area of the power board (20) so as to be in close contact with the plurality of IPM modules (204). The modules in the power unit module of the application are separately packaged and installed, so that the modules can be individually repaired and customized, the reusability is high, and the design and maintenance costs are reduced.
