FIELD: electromagnetic vibration systems; electric couplings, acoustic and hydroacoustic transducers, vibration-test facilities, and other vibration equipment. SUBSTANCE: coaxial electromagnetic system has stator magnetic circuit in the form of torus, inductance coils, and armature magnetic circuit. Stator magnetic circuit incorporates member with permanent magnet, face and rear linings. Permanent-magnet poles are oriented along radius, placed between face and rear linings, and form permanent-inductance air gap together with armature magnetic circuit. EFFECT: improved design. |
