Abstract

This paper presents the design of a new type of magnetic constant torque mechanism. The constant torque is shown to be created over a prescribed ±65° stroke length and is shown to be highly uniform. The value of the constant torque is adjustable through the relative axial motion of the rotors. The constant torque is created using a simple magnet arrangement which makes use of the axial transverse-flux path of one rotor's magnetic field relative to the azimuthal field flow of the fixed secondary rotor. It is shown that the use of segmented magnets introduces torque ripple.
