With the rising interest in wearable robot, a lot of researches on the wearable robot is being conducted on
aspects of both mechanism and control. On the other hand, although the optimization of the motor has a great effect on the
performance of the overall system, research on the motor of the wearable robot remains relatively insufficient. Thus, this paper
focuses on a proper design process of the motor of the wearable robot. At first, the surface-mounted permanent magnet
synchronous motor (SPMSM) is adopted for its high power density and controllability. Then, the considerations in design of
the motor for the wearable robot application are defined and categorized into dimensional, electromagnetic, and thermal
requirements. Having taken these into consideration, electromagnetic and thermal multi-physics design for the
SPMSM is conducted. For the electromagnetic design, the space harmonic analysis (SHA) is used, and for the thermal analysis,
lumped parameter thermal network (LPTN) is used. Following the proposed design process, the optimum SPMSM is designed
and manufactured. Finally, experiments of the SPMSM are conducted and the validity of this study is verified.
