Title:
CONSEQUENT POLE-TYPE ROTOR, ELECTRIC MOTOR, AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2018/025407
Kind Code:
A1
Abstract:
This consequent pole-type rotor includes a first core having a pole center 62 and a pole center 63 on the outer circumferential surface 71, wherein the first core has: a pole interval 64 which is arranged, in the outer circumferential surface 71, between the pole center 62 and the pole center 63; a magnet insertion hole 2B into which a permanent magnet is inserted and which has an opening 73 in the pole interval 64; a first end 74a1 which is formed between the pole center 62 and the pole interval 64; and a second end 74a2 which is formed between the pole interval 64 and the opening 73. Accordingly, reduction in magnetic force due to magnetic flux leakage is suppressed so as to improve efficiency while manufacturing cost is reduced.
