  • Abstract The design procedure for a magnetic geared motor with axial flux to assist the sit-to-stand motion of elderly adults is presented in this paper. The machine uses two rotors rotating in opposite directions, and each consists on axially magnetized permanent magnets and are magnetically coupled through an iron yoke. The magnetic equivalent circuit modelling is used to calculate both the output torque of the motor set and the pull-put torque of the gear set. The dimensions for an initial design was determined by finding the intersection of these torques within the size constraint of the application. A 3-dimensional finite element analysis was used to validate this initial design and machines with similar dimensions were compared according to their pull-out torque and maximum load torque supported. The final design was tested under the simulated load conditions for a standing-up motion and proved capable of aiding a person in standing up.
