Due to their low inertia and high acceleration, voice coils are used in applications that require fast dynamic response and high positioning accuracy, such as loudspeakers, hard disk drives and precision packaging machines. A moving component of a voice coil is a multi-turn coil that interacts with the permanent magnet field to produce strong mechanical forces. To characterize the performance of a voice coil, it is important to know its force and impedance characteristics.

Join us to see how you can use EMS to calculate the coil's force dependency on the current and displacement, as well as the impedance variation with the frequency
