摘要 |
A rotor for a rotating electrical machine suppresses demagnetization of permanent magnets without deteriorating motor characteristics, is low-cost, and is highly reliable. The rotor has a plurality of rotor cores (2) that are stacked together, a plurality of permanent magnets (6a, 6b) axially divided by the rotor cores (2) and circumferentially arranged on each of the rotor cores (2), to circumferentially form magnetic irregularities, and a rotor blank (14a) made of nonmagnetic material arranged between those of the rotor cores (2) that are adjacent to each other. |
