Abstract
The stator for an electromagnetic pump is designed to improve output efficiency of the pump by decreasing leakage flux. An air-core electromagnetic coil (50a, 50b) is fitted around periphery of a cylinder, and axial end faces of an electromagnetic coil (50a, 50b) are provided with yokes (26a, 26b, 26c) made of a magnetic material.
