Abstract
A magnetic cogging parallel-elastic actuator (100) can include a motor (102) having an output shaft (104). The actuator (100) can further include a cogging-torque element (106). The cogging-torque element (106) can include a stator that is stationary relative to the motor (102) and a rotor that is rotatable relative to the stator and comprises an output shaft (104). A plurality of stator magnet elements can be disposed radially about the stator and a plurality of rotor magnet elements can be radially positioned about the rotor. The output shaft (108) of the rotor of the cogging-torque element (106) can be connected in parallel with the output shaft (104) of the motor (102) such that an output torque of the actuator (100) is a sum of a torque of the cogging-torque element (106) and a torque of the motor (102).
