Abstract
Electromagnetic inertial force generators are provided, which include radially polarized permanent magnets providing bias flux across axial gaps to combine with axial coil flux to linearize the actuator output. Coil cooling in the electromagnetic inertial force generators is improved by embedding the coils in the stationary portion of the actuator, allowing for direct transfer of coil heat, and reducing oscillating stresses on coil leads.
