Abstract
Design and control of multi degrees of freedom (DOF) electromagnetic actuators often require understanding the magnetic fields of a permanent magnet (PM), an electromagnet (EM) and a magnetic material boundary. This paper presents an image method to characterize the magnetic field of a permanent magnet (PM), magnetic conducting boundary, and its use in computing the magnetic torque of PM-based actuators. In particular, the method offers an effective means to optimize design parameters that could significantly affect the torque and force performance of a multi-DOF electromagnetic actuator. While developed in the context of the multi-DOF actuator, the modeling techniques presented in this paper are applicable to design of other PM-based actuators.
