A modular actuator control system comprising first and second actuator control modules configured to control first and second actuators and each having a housing, control and power electronics, power and communication connections, an actuator power connection, a flow path in each housing between an inlet and outlet port that is configured to provide a liquid coolant to the power electronics in the housing, an attachment connecting the first and second housings of the first and second actuator control modules, and a coolant inlet port of the first actuator control module configured to connect to a fluid coolant source and a coolant outlet port of the first actuator control module connected to a coolant inlet port of the second actuator control module, wherein the first actuator control module and the second actuator control module are stacked in coolant fluid communication with each other.

Modular rugged cooled actuator control system

An electric motor assembly comprising a housing containing a secondary power source, a motor driver, an electric motor, power sensors to sense faults in a primary power supply and the secondary power source, primary and secondary winding sensors configured to sense faults in a primary winding and a secondary winding of the electric motor, the motor driver comprising a primary controller to control the primary winding in a normal operation mode and a secondary motor controller operatively configured to control at least one of the primary winding and/or the secondary winding in a secondary operation mode, the secondary motor controller configured to drive the motor to a safe position using the secondary winding in the event of a sensed fault in the primary winding and to drive the motor to the safe position using the secondary power source in the event of a sensed fault in the primary power source.

Fault tolerant actuator assembly

A method for charging an electric emergency energy storage device () comprising the following steps: predicting the energy demand Eof the energy consumer (), determining the capacitance C of the emergency energy storage device () and the internal resistance Rof the emergency energy storage device (), calculating a charging voltage U, whereby the charging voltage Uis calculated in such a way that the energy Estored in the emergency energy storage device () at this charging voltage Uis just enough to meet the predicted energy demand E, taking into account losses that occur, especially at the internal resistor R, and charging or discharging the emergency energy storage device () until the calculated charging voltage Uhas been reached.
