Title:
STATOR CORE STRUCTURE OF MOTOR
Document Type and Number:
Japanese Patent JP2007110861
Kind Code:
A
Abstract:
To provide the stator core structure of a motor by which a high efficiency motor can be obtained by enhancing a magnetism collection effect of a magnetic circuit.
A rotor 11 comprises a shaft 12 and a permanent magnet 14 magnetized with a plurality of poles and supported rotatably by a bearing (not shown). A stator 15 comprises two blocks of stator blocks 15a and 15b and opposing the outer circumferential part of the rotor 11 through a predetermined gap. The stator blocks 15a and 15b are composed of laminated grainoriented electromagnetic steel sheets, and its magnetization-facilitated direction 19 is identical to the inflow direction of magnetic flux.
