Title:
ROTOR OF DYNAMOELECTRIC MACHINE
Document Type and Number:
Japanese Patent JPH11252840
Kind Code:
A
Abstract:
To provide the rotor of a dynamoelectric machine which is capable of realizing a large capacity, high revolution, high performances (a high responsiveness and a high torque) and low cost.
The rotor of an embedded magnet type permanent synchronous servomotor has a rotor core 11, which has head parts 11a of which poles are composed, a cylinder part 11c and yoke parts 11b which are transition parts between the head parts 11a and the cylinder part 11c. Each yoke part 11b is positioned so that it is positioned at the center of each head part 11a. Two permanent magnets 12 and 13 are disposed on the left and right sides of each yoke part 11b. Furthermore, two long holes 11d and 11e are formed symmetrically in each head part 11a.
