This paper presents a 3-D analytical study of the linear electromagnetic force and rotary electromagnetic torque of a novel linear and rotary permanent magnet actuator (LRPMA). The 3-D analytical magnetic distribution of the LRPMA is established using the magnetic scalar potential and modified BESSEL functions in the cylindrical coordinate system. Linear electromagnetic force and rotary electromagnetic torque, respectively, are derived and verified using finite element method (FEM) for the characterization and optimization design of the LRPMA being examined by experiments in this paper.
