Neutralizing magnetic component arrangements in a variable aperture device

A device, comprising:

• one or more processors;
• memory storing program instructions executable by the one or more processors to control operations of a camera;
• and
• the camera, comprising:
• a variable aperture device, comprising:
• a stator;
• a rotor;
• aperture blades arranged to form an aperture stop, wherein the aperture blades are coupled with the stator and the rotor, and wherein the aperture blades are movable to change a size of an aperture defined by the aperture stop;
• an actuator for rotating the rotor, relative to the stator, about an axis that is parallel to an optical axis of a camera, wherein the actuator comprises of two or more actuator magnets coupled with the stator or the rotor;
• two or more neutralizing magnets, wherein the two or more neutralizing magnets are positioned with respect to the two or more actuator magnets to cause a neutralizing force on the rotor based on respective magnetic fields and magnetic polarities of the two or more actuator magnets, wherein the neutralizing force reduces torque and forces exerted on the rotor by the magnetic fields and the magnetic forces from the two or more actuator magnets;
• and
• wherein the variable aperture device is operable such that:
• when a threshold amount of power is supplied to the actuator, a rotational force produced by the actuator is sufficient to rotate the rotor, relative to the stator, about the axis, to change the aperture size, wherein the rotational force produced by the actuator is reduced at least based on the neutralizing force.
