Robot Actuator Control Board Layout for Compact Power and Cooling

The patent combines the servo control board and brake control board into a single integrated control board. The control board includes both a servo control unit for controlling the servomotor and a brake control unit for controlling the electromagnetic brake, eliminating the need for separate control boards and reducing overall device size while maintaining full power supply capability.

The control board is designed as a multi-functional unit that performs both servo control and brake control functions. By integrating multiple control functions into a single board with shared power supply circuits, the device achieves universal control capability without requiring separate dedicated boards for each function.

The patent employs asymmetric arrangement of the amplifier board and brake power supply unit, positioning them on opposite sides of the control board rather than in a symmetric configuration. This asymmetric layout optimizes thermal management by creating effective cooling pathways while simplifying the overall structural design compared to more complex symmetric arrangements.

The amplifier board and brake power supply unit are arranged in a spatial configuration that utilizes three-dimensional space efficiently. By positioning these components to face each other across the control board, the design creates vertical and horizontal separation that enhances cooling airflow paths without requiring additional lateral space, effectively using dimensional arrangement to solve thermal management.
