17 Resonant Linear Oscillatory Single-Phase PM Motors/Generators
17.1 Introduction
Fixed frequency linear motion applications [1] such as compressors, pumps, vibrators, as well as speakers/microphones use linear oscillatory single-phase PM motors (LOMs), while short-stroke (up to 20 mm in general) applications use linear single-phase PM generators (LOGs) such as Stirling engines or other linear piston engines due to
Elimination of rotary to linear motion mechanical transmission
Simplicity and ruggedness of their topology
Rather high efficiency and high force density, especially with mechanical springs and operation at resonance frequency (mechanical eigenfrequency = electrical frequency)
Simplicity (single-phase PWM converter) for close-loop ...
