Abstract

PURPOSE: To obtain a simple structured magnetic bearing of strong axial rigidity by means of three respective opening magnetic paths between a rotor and a division of a stator, one electromagnetic coil and one permanent magnet.
CONSTITUTION: A rotor 1 consists of one yoke 3 comprising a magnetic substance. A stator 2 is divided at least into three pieces and interconnected by a non-magnetic connector 7. Each division 2aW2d of this stator 1 consists of cross- sectional rectangular yokes 8aW8d and cross-sectional angular frame electromagnetic yokes 9aW9d with opened upside. Permanent magnets 10aW10d are placed between the yokes 8 and 9 and electromagnetic coils 11aW11d are placed in a part of the electromagnetic yoke 9 respectively. Three opening magnetic paths 13, 14 and 15 are formed between the rotor 1 and the stator 2. Since the first opening magnetic path 13 is an exclusive path for magnetic flux ϕ1 of a magnet 10 and magnetic flux density need not be controlled by magnetic flux ϕ2 from the electromagnetic coil 11, magnetic flux can be fully elevated.
