Modular rugged cooled actuator control system

A modular actuator control system, comprising:

• a first controller module configured to control an electrically powered first actuator having at least one motion axis;
• a second controller module configured to control an electrically powered second actuator having at least one motion axis;
• said first controller module comprising:
• a first housing;
• first control electronics in said first housing;
• first power electronics in said first housing;
• a first power connection configured to connect to a master power source;
• a first communication connection configured to connect to master controller electronics;
• a first actuator power connection configured to connect said first power electronics with said first actuator;
• a first coolant inlet port;
• a first coolant outlet port;
• and
• a first flow path in said first housing between said first coolant inlet port and said first coolant outlet port that is configured to provide a liquid coolant to said first power electronics;
• said second controller module comprising:
• a second housing;
• second control electronics in said second housing;
• second power electronics in said second housing;
• a second power connection configured to connect to said power source;
• a second communication connection configured to connect to said master controller electronics;
• a second actuator power connection configured to connect said second power electronics with said second actuator;
• a second coolant inlet port;
• a second coolant outlet port;
• and
• a second flow path in said second housing between said second coolant inlet port and said second coolant outlet port that is configured to provide said liquid coolant to said second power electronics;
• an attachment connecting said first housing of said first controller module and said second housing of said second controller module;
• said first coolant inlet port of said first controller module configured to connect to a fluid coolant source;
• and
• said first coolant outlet port of said first controller module connected to said second coolant inlet port of said second controller module;
• wherein said first controller module and said second controller module are stacked in coolant fluid communication with each other.
