Linear Motion Electromagnetic Devices

Linear electric motors (LEMS) produce directly linear, progressive or oscillatory linear motion through electromagnetic forces. LEMS enjoy small, but very dynamic, worldwide markets in various applications, such as urban and airport people movers, loudspeakers, relays, door-lock openers, magnetic bearings, vibrators, refrigerator compressors, and small vacuum or liquid pumps. This book discusses linear induction motors, linear permanent magnetic synchronous motors, linear permanent magnet pulse motors, linear (plunger) solenoids with fast response, and linear oscillomotors. A disk containing Mathcad codes for the examples is included
