Actuators for control are indispensable for the optimal performance of system functions, and their selection is dependent on many factors. This first publication in English of advanced Japanese research provides a clear and concise description of the design, manufacture and applications of various actuators used in modem control systems. Miniature linear motors, hydraulic and pneumatic actuators, servo motors, AC and DC control motors and stepping motors are discussed by leading Japanese researchers, while the volume concludes with a forward-looking examination of the actuators of the future: bio-engines and those utilizing functional materials. Translated from the Japanese. Volume II. This volume will be invaluable to postgraduate and research engineers and to machinery system design and manufacturing engineers in industry.
