In the frame of the Meteosat Third Generation project (MTG), the future European Operational Geostationary Meteorological Satellites system, Cedrat Technologies has developed a dedicated actuator for the Scan Assembly mechanism (SCA) made by SENER. Such motors are needed to actuate the SCA on the north/south (N/S) and east/west (E/W) axes. The requirement of precise pointing of the SCA induces very specific characteristics for the motorisation. The motor needed characteristics are: to be free from any cogging, high constant motor [N.m/√W] to have a constant torque over full stroke range, to have a very low hysteresis and to have redundant coils. To meet these stringent requirements, the choice was made to develop a specific Rotating Voice Coil Motor.
The goal of this paper is to present the motor that meets these requirements. The first part will focus on the approach that leads to the selection of the architecture and magnetic materials. It will point out on the main issues that are the torque characteristic, the power consumption and the masse reduction. Then, the actuator by itself will be presented, associated with the expected performances. To conclude, the test results of the Elegant Bread Board (EBB) Model will be summed up.
