Rotary reluctance input device with asymmetric poles

Abstract

A torque feedback mechanism for a trigger or lever using a rotary reluctance engine is disclosed. In some examples, the rotary reluctance engine includes two fixed asymmetric core/coil assemblies located on one or both sides of a permanent magnet. In some examples, the core/coil assemblies are fixed in place, and the permanent magnet is coupled to the trigger or lever such that the magnet rotates with respect to the core/coil assemblies as the trigger or lever is squeezed. When the coils of the engine are programmably energized, the cores are magnetized at different angular rotations of the trigger or lever, creating a torque feedback profile that can be quickly modified to provide more or less torque at different angular displacements during the squeezing of the trigger or lever to emulate different triggers or levers.
