초록
A lot of rotating machinery are generally used in industrial field and the electrical machinery such as the motor and generator account for the most of the part. Generally motor and generator have electrical loss because of eddy current. So silicon steel sheets are used in order to reduce the electrical loss and furthermore laminated rotor is used for motor and generator to eliminate the electrical loss and heat generation. However, the more high speed, large scale and high precision of the system, the more important to estimate the critical speed. In this paper verifies the variation of the critical speeds in accordance with the variation of the pressing force of lamination plate for the rotor which is supported by ball bearing with the experimental data as well.
