图书简介
Linear motion is richly present in various industries, from direct electric propulsion in urban and interurban people movers on wheels or on magnetic “cushions” (MAGLEVs) to indoor transport of goods (conveyors, etc.), through plunger solenoids (to open hotel doors and as electromagnetic power switches), to compressor drives by linear oscillatory permanent magnet (PM) motors, smart phones integrated microphone and loudspeakers, and controlled vehicles’ suspension, etc. Besides the traditional rotary motor drives with mechanical transmissions, which mean friction limitations (weather dependent) in traction (heavy vehicles), more losses, positioning errors (backlash) in the process, and higher maintenance costs to handle them, linear motion in industry by direct electromagnetic forces is free of friction limitations for traction, free of mechanical transmission, and thus more efficient, with less maintenance cost and fewer positioning errors (backlash). This explains why they are used in so many applications already since the dramatic advancement of power electronics and digital control in the last four decades.Modeling, performance, design, control, and testing of linear electric machines (LEMs) show notable differences with respect to rotary electric motor drives, which warrant a dedicated treatment of these aspects.The Second Edition (First Edition: 2013) concentrates on the above technical aspects of various types of LEMs in close relationship with specific applications via numerical examples of modeling, design, control, and testing, with ample representative results from literature, industry and some of the author’s contributions, such as:Technical field and circuit modeling of linear induction motors in flat configurations for low and high speeds (with and without dynamic end effects) and in tubular configurations short travel design, control and testingLinear synchronous motor (LSM) driv
