- Abstract
- This paper discusses the analytical design method of a 125W surface-mounted permanent magnet synchronous motor (SPMSM) as an actuator for an exoskeleton wearable robot. Considering the properties of the wareable robot application, pole and slot combination is determined to minimize vibration as well as cogging torque. In addition, the shape of the magnetic core and permanent magnets are determined by using the analytical approaches including space harmonic analysis (SHA) to maximize torque density as well as minimize cogging torque and torque ripple, simultaneously. As a result, the SPMSM which has high torque density with small axial length, low cogging torque/torque ripple and a large hollow rotor is designed.
