Cage Rotor

3kW two poles induction motor with compound cage rotor is illustrated in this paper, and 2-D thermal stress field of induction motor rotor is calculated and analyzed by finite element. Contrasting with common induction motor, induction motor with compound cage rotor has specific rotor shot shape and the bar is comprised of the upper compound material and the lower cast aluminium, which cause distribution of thermal stress is special. The motor with the rotor shot of compound material laid at single site is chosen to analyzing. The maximum thermal stress in the bar is calculated at different load, and the distribution of thermal stress in the bar is analyzed at rate load. The law of distribution of thermal stress in the bar has same reference value for designing new type of induction motor.

Good Accordance

Depending on the solar radiant flux and velocity measured in Harbin, with finite element method, use a modified radiant heat flux function to calculate the temperature field of a plate on the focal region of a dish solar concentrator. Compared the result with picture taken by infrared camera, there is a good accordance between them. The temperature field is used as the loading parameters to calculate the thickness’s impact on the thermal stress field in the plate. When the value of the thickness increases, the maximum values of the stress increase, but the overall stress field tend to decrease.
