    The design of a flexure-based suspension for a high-torque, iron-core directdrive motor is presented. Over the full, large range of motion, the design provides the high radial stiffness (> 1,000 N/mm) required for resisting the high magnetic forces from the permanent magnets and iron core. Furthermore, it maintains a constant position of the pivot axis within 0.1 mm, to meet alignment tolerances. A prototype was realised and experimental validations have confirmed its high radial stiffness and applicability for iron-core torque motors.
