Synchronous Motor, like induction motor, is a commonly used AC motor. Synchronous motor is the heart of power system, it is a set of rotating and static, electromagnetic and mechanical changes in one motion, electric energy and mechanical energy conversion element, its dynamic performance is very complex, but also greatly affect the dynamic performance of the whole power system dynamic performance. The characteristics are: steady state operation, the rotor speed and the frequency of the grid has a constant relationship between n=ns=60f/p, where f is the grid frequency, P is the pole of the motor, NS is called synchronous speed. If the frequency of the grid is constant, the speed of the synchronous motor is constant at steady state, independent of the magnitude of the load. Synchronous motor is divided into synchronous generator and synchronous motor. The alternator in modern power plant is mainly synchronous generator.

LED is not just an illuminated Nobel Prize winner to actively promote medical applications
In the interview, Tianye Hao, a winner of the 2014 Nobel Prize in Physics and a professor at Nagoya University in Japan, said that he plans to promote research on the application of light-emitting diode (LED) technology in the medical field. Amano emphasizes that LEDs continue to expand in addition to lighting. He said that ongoing research covers a wide range of fields, including laser displays, equipment for treating skin diseases, and water purification equipment. For medical use, Amano and the Nagoya City University have jointly developed treatment equipment for treating psoriasis and vitiligo with ultraviolet radiation, and mass production is now possible. It is said that in the field of laser displays, a red laser source that can project information onto the front window of the car has been developed and is planned to be put into practical use within five years. Professor Nagasaki (85), Professor of Nagoya University, Professor Nagano (54) from Nagoya University, and Nakamura Shuji (60), a professor at the University of California, USA, shared the 2014 Nobel Prize in Physics with the invention of blue LEDs. .
