Future "more electric aircraft (MEA)" will require electric actuation systems for control surfaces, and engine controls. Electric motors, drive electronics and mechanisms are essential elements of aircraft actuation in MEAs that incorporate Electro-Magnetic Actuators (EMA). High temperature environments experienced in aircraft applications place demands on actuator components, materials and insulation systems that dictate the use of new technologies and materials. RCT Systems has experience with custom motors, high power, high density electronics and high temperature oil free bearing systems and the ability to evaluate, design and implement custom high temperature motor and mechanical systems. This paper reviews High Temperature Electromagnetic Actuator (HTEMA) options for high temperature aircraft environments including appropriate motor types, drive and control electronics, mechanisms, materials and construction methods. These options are evaluated to identify candidates that meet the challenges of tomorrow's more electric aircraft actuators.
