voice coil motor design resource?

[brashear]

Hi all,
I'm trying to design a voice coil motor and was wondering if there are any good books out there to help? The force is pretty easy to obtain using Lorentz equation, but I'm not sure if I'm getting the correct values for inductance and back-EMF. Thanks

Go to Application Notes of BEI Kimco - world leader in manufacturing of voice coil motors.

If the units of the Force Constant are in Newton/Amp, the BEMF will be the same numerical value in units of Volts/meter/sec.
