There are people believe that the ancient Chinese form was originally a concept-day geodetic instruments, Spring and Autumn Period there is a instrument for the observation of astronomical tables, people standing tree as a pole in order to determine the length of the sun's shadow position, solar terms, and thus to measure the star, observable sidereal year cycle, the ancient pre-construction in the construction, but also as a method to take positive positioning.

还有人认为，古代的中国形式的概念最初是天大地测量仪器，春秋有一个表的天文观测仪器，人们站在一个极树，以便确定太阳的阴影位置长度，节气，从而测量恒星，观测恒星年周期，古代前在建筑施工，但作为一种方法也采取积极的定位。

In this paper, arrangement scheme of a novel multi-star phase shifted pole changing coil was given and the methods to determine coil split ratio were analyzed. According to electromagnetic theory, 2D electromagnetic mathematical model in which stator windings were spitted coil was developed, and magnetic field distribution of the novel motor at starting was solved by finite element method, starting performance of motor was calculated. Based on energy method, rotor slot leakage reactance under different poles and different loads were calculated, and the variation of rotor slot leakage reactance with loads was gotten. Based on time-step finite element method, distribution of branch current in stator windings and operating performance were calculated and analyzed when branch was unbalance, the method to calculate circulating loss in stator windings of novel multi-star phase shifted pole changing motor was given, and the effects of the loads variation and degree of unequilibrium on circulating loss in stator windings were calculated and analyzed.
