Permanent Magnet Motor Design for Satellite Attitude Control With High Torque Density and Low Torque Ripple [PDF]
IEEE Access, 2020 This paper proposes a high-precision permanent magnet (PM) motor primarily used for the satellite attitude control. Considering aerospace applications, the dynamic response, weight and torque ripple are primarily concerns. To achieve the fast response and low ripple, a stator with slotless windings is designed to achieve the ripple free torque ...
