Abstract

PURPOSE: To improve the cooling effect while keeping the efficiency and the power- factor good by providing a cooling air hole in the stator or rotor core at the position located in a specific area of the core-back on the central line of each slot tooth.
CONSTITUTION: The dimension S3 of the core back 1c of the stator core 1 is made 0.5∼1.5 times of the depth S1 of the slot 1a, the cooling air hole 3 is provided on the central line of the slot tooth 1b. At this time, the distance S4 between the center of cooling air hole 3 and the bottom of slot 1b is made 1/2 of the dimension S3 of the core back, and the distance S5 between the outer circumference of cooling air hole 3 and the bottom of slot is made 1/2 or more of the width S2 of the slot tooth. Also, in the case of the cooling air hole 4 in the rotor core 2, the same relations are adopted. In this way, the cooling effect can be improved without a drop of the electrical characteristics such as the efficiency and power-factor.
