Abstract
PURPOSE: To provide a rotation speed detecting device for a hydroextractor. The rotation speed of the hydroextractor is determined from induced voltage which is generated at starting windings of an single-phase induction motor of the hydroextractor. The induced voltage is in proportion to the rotation speed of a rotor.
