【発明の名称】直流モータ型位置決め装置の駆動制御方法
Document Type and Number:
Japanese Patent JP2712749
Kind Code:
B2
Abstract:
PURPOSE:To keep the variation of a targetted numerical value within a prescribed numerical value range even in the case of the variance of a control input by updating a target value at the time when the target value is deviated from the actual numerical value of an object by a prescribed value or more in a DC motor type positioning device. CONSTITUTION:An output shaft 15 of a DC motor 13 of a positioning device is connected to a variable intake control valve 11 through a power transmission path 16. A wheel 23 is engaged with a work gear 22 attached to the end part of a revolving shaft 20 and is attached to a valve shaft 24 of the variable intake control valve 11. In such constitution, the DC motor 13 is driven to control the degree of opening of the control valve 11. A rotation sensor 25 is provided with a ring magnet 27a fixed to the peripheral surface of the revolving shaft 20. When the ring magnet 27a is rotated to a magnetic probe 29a, the signal from the rotation sensor 25 is outputted pulse mode as turning-on and turning- off signals.
