Everything you ever wanted to know about oscillating motors

This book provides a comprehensive, in-depth exploration of oscillating motors — also known as limited-rotation or limited-travel motors. While continuous-rotation motors dominate everyday awareness, oscillating motors are essential in countless high-performance applications, yet surprisingly few resources have been written about them.

The authors begin with the fundamental similarities and differences between continuous-rotation and oscillating motors, then dive deeply into how these specialized motors work, how to model them mathematically, how to analyze their behavior, and how to optimize their performance. The book is rich with formulas, derivations, comparison tables, graphs, and MATLAB code examples that allow readers to directly apply the concepts.

Special emphasis is placed on the motor topologies most commonly used in high-performance applications, including Limited-Angle Torque Motors (LATMs), Conventional Moving-Magnet Actuators, the advanced ScannerMAX “Saturn” Moving-Magnet design, and Linear Voice-Coil Actuators (including loudspeakers). Additional topics include efficiency analysis, compliance and resonance, power conversion, figures of merit, and optimal drive techniques.

Whether you are a practicing engineer, researcher, or technical professional seeking to master the design and optimization of oscillating motors, this book delivers the detailed technical knowledge that has been largely unavailable until now.
