ACTUATOR HAVING VALANCE MECHANISM FOR 3 DIRECTION BY THE 2-WAY MAGNETISM INDUCTED, THE MAGNETIC BEARING AND MAGNETIC LEVITATION APPARATUS THEREOF

摘要

PURPOSE: An actuator having a driving mechanism for 3 directions by 2-way induced magnetism and a magnetic bearing and a magnetic levitation apparatus using the same are provided to be economically operated by minimizing required electrical energy consumption. CONSTITUTION: Actuator is composed of first and second core(311a,311a'), second coils(311b,311c) surrounding first and second poles, and a permanent magnet(311d) inserted between the first and second cores. The first and second poles are formed on the same plane in consideration of the volume of the first and second cores and the space occupation efficiency of the first and second coils. A steel sheet forming the first and second cores is made of a flat board. The first core has two poles respectively projected in two ways. The second core has two poles respectively projected in the two ways. The first core and the second core are evenly separated from each other.
