Development trends in aeronautics involve a better employment of electric motors also in safety critical hazardous applications until now covered by mechanical systems. The electromechanical actuators (EMAs) are gaining a growing interest owing to their force and power density capability and the high dynamical performance by electronic control. Hence, very(More)
The concept of reliability and safety is the foundation of every kind of system used in the aeronautical and aerospace applications and diagnostics contributes significantly to this goal. In the literature there are several methods (thermal, on test bench, etc...) that perform diagnostics of electric motors both in the production phase and in the test phase(More)
This paper describes the analysis and design of an Electromechanical Actuator (EMA) that have been developed to open and close a gate valve for oil and gas applications. The rotating permanent magnet (PM) synchronous motor is integrated with the mechanical components in a rotating-ball nut architecture to minimize the total length and envelope of the(More)
This paper represents the design concepts and the test results of a Permanent Magnet Synchronous Motor (PMSM) for an electro-mechanical actuator used in a laser-cutting applications, for the dynamic focus adjustment. The motor is directly integrated with the mechanical components in a rotating-ballscrew architecture in order to minimize the total inertia(More)
This paper focuses its attention on the wave energy converters (WEC), particularly the ones that use a moving body (wave activated bodies) coupled directly to a power take-off (PTO). It describes the analysis and the design of a small reciprocating linear permanent magnet generator. A comprehensive design methodology, which embraces both the electromagnetic(More)
This paper describes requirements and design principles of an electric motor for helicopter tail rotor application. The application demands high specific power and specific torque with little possibility to adopt a liquid cooling solution. The tail rotor shall also comply with severe safety requirements that directly affect the motor design. Volume and(More)
This paper presents the design concepts and the test results of a Permanent Magnet Synchronous Motor (PMSM) for an electro-mechanical actuator used in a laser-welding machine for the dynamic wobble of the beam. The motor is directly integrated with the mechanical component in a rotating architecture in order to minimize the total inertia and the actuator's(More)
Linear Electro-Mechanical Actuators (LEMA or EMA) are becoming increasingly used in various areas and locations around the More Electric Aircraft (MEA). One application following this trend is the High Lift System. Several system configurations have been designed and evaluated, then focused on the more suitable EMA which is proposed in this document. The(More)
