Abstract :
This paper describes wet-type brushless DC motor driven by a single sided matrix converter (SSMC) as pump drive in an electro-hydraulic actuation (EHA) system for aerospace application. The use of an SSMC with a brushless DC motor is novel and is used to achieve operation without a microprocessor. A simple hysteresis current control strategy is implemented to control motor torque. The motor power rating is 12kW at 12,000 rpm and a "wet" form of construction is used where hydraulic oil is present in the motor in order to reduce the number of oil seals. Fault tolerance has been discussed for brushless DC motor and SSMC in this paper
