Apparatus measuring relative velocity of movable members including means to detect velocity from the position encoder

摘要: A transducer coupled to a motor shaft provides both position and velocity information for use in closed loop control system. The includes disk with deposited metallic parallel conductors each conductor carrying current direction opposite the adjacent conductor. Relative movement of one respect another produces signal manner well known art. However, multiple windings are used provide signals displaced space phase which then processed by differentiation commutation as voltage loop. reference is also derived from signal.
