FIELD: electrical engineering.
SUBSTANCE: electromagnet drive has unmovable base magnetic circuit, at least one permanent magnet, control coils , and movable core made of two members, between which the fixed additional magnetic circuit with an opening is interposed. The additional magnetic circuit abuts against the permanent magnet, receives an additional rod, and has through central opening for receiving an additional carrying member made of, e.g. shaft. The both ends of the shaft are set in the openings of additional carrying plates made of nonmagnetic material.
EFFECT: enhanced reliability.
