Linear Electric Motor of Moving Coil Type
Linear electric motors (LEMs) are electromechanical devices which produce motion in a straight line directly, without the use of a mechanism to convert rotary motion to linear motion. The benefit over conventional rotary-to-linear counterparts is the absence of mechanical gears and transmission system, which results in a higher dynamic performance and improved reliability.The acceleration available from these motors is remarkably high, compared to traditional motor drives that convert rotary to linear motion.
This model analyzes the cross section of a coil, by using the perpendicular induction currents application mode and solving for the vector potential. The model also shows how to compute the Electromagnetic forces from the command line, using the command cemforce.
