Title:
アーマチュア／フィールド間ギャップを確立する機械的フレキシャを有するトルクモータ
Document Type and Number:
Japanese Patent JP6587753
Kind Code:
B2
Abstract:
A torque motor has a mechanical reference member, an armature, and a field assembly. The field assembly includes field pole pieces defining a pole opening, and the armature is mounted to the mechanical reference member for rotation about a motor axis and extends into the pole opening with respective gaps to the field pole pieces. The field assembly is secured to the mechanical reference member and spaced therefrom by elastically deformable flexures, deformed sufficiently to locate the armature at a predetermined position within the pole openings with corresponding lengths of the gaps. During manufacture, a load can be applied to move the field assembly relative to the mechanical reference member against the deformation force of the flexures to locate the pole opening relative to the armature pole piece such that the gaps of desired lengths are formed.
