Abstract:  Based on a profound analysis of fractional slot, this article gave an interpretation of the fractional slot from the new perspective. The new way of understanding method corresponded with the new vector diagram of the main harmonics. In the analysis, the concept of fractional slot motor element is introduced, the simplified vector analysis of fractional slot motor was achieved, and at the same time, the amount of fractional slot motor’s cycle was determined quickly, the distribution of slot winding was finished, the process of coiling was realized. The concept of fractional slot was ported to the linear motor, and used the Ansys software to simulate the electromagnetic field of fractional-slot linear motor.
Key words:  fractional slot; vector diagram; low speed linear motor; simulation of electromagnetic field
