Document Type and Number:
Japanese Patent JP7150181
Kind Code:
B2
Abstract:
An electric motor includes: a permanent magnet; a rotor including a first rotor core having a first electrical steel sheet and a second rotor core having a second electrical steel sheet; and a stator including a stator core. The first electrical steel sheet is located outside the stator core. A relationship among a minimum width BL1 of a first left bridge, a thickness tL1 of the first left bridge, a minimum width BR1 of a first right bridge, a thickness tR1 of the first right bridge, a minimum width BL2 of a second left bridge, a thickness tL2 of the second left bridge, a minimum width BR2 of a second right bridge, and a thickness tR2 of the second right bridge satisfies (BL1×tL1+BR1×tR1)>(BL2×tL2+BR2×tR2).
