Abstract: This paper presents the characteristic analysis of the
two-degree-of-freedom cylindrical actuator that can move in rotary and linear
direction. The actuator uses the permanent magnet that is magnetized in axial
direction so that the polarity in rotary and linear direction is generated
alternately. When the rotary coil or the linear coil is excited, the mover
moves by the principles of PMSM or PMLSM, respectively. As a result, the torque
and the thrust are almost out of interference. It was confirmed that the
actuator can move in rotary and linear motion independently. Moreover, the iron
loss of the mover is smaller than that of the stator in rotary and linear
motion, and the hysteresis loss is much larger than the eddy current loss.
Keywords: Two-degree-of-freedom, PMSM, PMLSM, iron loss, finite element method
