Title:
ELECTROMECHANICAL CONVERTER
Document Type and Number:
WIPO Patent Application WO/2022/181490
Kind Code:
A1
Abstract:
In the present invention, a rotor provided at one end part of an armature is inserted in a cylinder provided at a closed end part of a yoke, and the armature and the yoke are joined with a bearing interposed therebetween. There is a slight gap between the rotor and the cylinder, and when AC current flows through a coil, the armature oscillates around the axis relative to the yoke. If the outer diameter of the rotor and the inner diameter of the cylinder are increased, a large opposing area for both can be ensured, the gap between both can be reduced, and magnetic resistance can be kept sufficiently low.
