Document Type and Number:

Japanese Patent JP7005131

Kind Code:

B2

Abstract:

According to one embodiment, a rotor includes a shaft and a rotor core. A plurality of flux barriers are formed at the rotor core. The flux barrier has a plurality of bridges, and one or more barrier regions. When a width of the bridge of a first flux barrier is defined as w, a width of the bridge of a second flux barrier is defined as w, a value obtained by dividing a radius of a smallest circle that is tangent to a central line of the first flux barrier by an outer radius of the rotor core is defined as a, and a value obtained by dividing a radius of a smallest circle that is tangent to a central line of the second flux barrier by the outer radius of the rotor core is defined as b, and when f(x)=(1-x^2)^(3/2) and g(x)=(1-x^3), a relationship of f(b)/f(a)≤w/w≤g(b)/g(a) is satisfied.
