EMBEDDED MAGNET TYPE MOTOR |
摘要 |
An embedded magnet type motor is disclosed. The rotor core of the motor has radially extending first accommodation holes and V-shaped accommodation holes. Each V-shaped accommodation hole includes a second accommodation hole and a third accommodation hole. A first gap is formed in each first accommodation hole. The first gap is not occupied by the corresponding first magnet. A second gap is formed in each second accommodation hole. The second gap is not occupied by the corresponding second magnet. A third gap is formed in each third accommodation hole at a radially outer portion. The third gap is not occupied by the corresponding third magnet. Each second gap and the adjacent third gap form one V-shaped gap. The angular width thetaa of each first gap and the angular width thetab of each V-shaped gap are determined to satisfy the expression: 0.60<thetaa/thetab<1.60.
