ABSTRACT
Linear electric motors belong to the group of special electrical machines that convert electrical energy directly into mechanical energy of translatory motion. Linear electric motors can drive a linear-motion load without intermediate gears, screws, or crank shaµs. Linear electric motors can be classiŸed as follows:
• DC motors • Induction motors • Synchronous motors, including reluctance and stepping motors • Oscillating motors • Hybrid motors
e application of DC linear motor is marginal. e most popular are permanent magnet (PM) linear synchronous motors (LSMs) and linear induction motors (LIMs), which are manufactured commercially in several countries and are Ÿnding many applications.
