摘　　要：本文介绍一种新的变极电机绕组设计原理,它以"安导元"作为基础。用此原理设计的变极绕组,无论变极前后都等效于整距绕组。文中论述了"安导元"的定义及以"安导元"为基础的变极原理,并给出设计方法,然后以8 2变极为例加以说明。This paper introduces a new principle of design for variable-pole motor′s winding. This principle of the design is based on ampere-conductor-unit in order that it adapts itself to different polar distance. By using it the variable-pole motor′s winding is equivalent to full-pitch-winding, whether the motor′s pole changing or not. By using traditional method of design based winding-unit, the variable-pole motor′s winding is shown with different short-pitch factor in different polar distance. The paper analyzes the cause of the winding short-pitch factor and presents the improved method of design. The paper gives a definition of ampere-conductor-unit, and presents this design principle based on ampere-conductor-unit for variable-pole winding. Then the design method is given with a 8/2 pole changing as example.
