Abstract：Based on the idea of sinusoidal random windings with low harmonics that are often applied to small and medium sized motors, the sinusoidal hard windings that can be applied to high voltage asynchronous motors are presented in the paper. According to the analysis on the harmonics of the sinusoidal hard windings and the differences between the hard lap windings and the random lap windings, the design method of the sinusoidal lap hard windings converted from the conventional double layer lap hard windings is introduced, which references to the design thought of sinusoidal random windings. The number of parallel branches and the stator parallel windings, the wire guage of the flat conductors and the turn number of the windings of -△connection are determined here. The results show that without increasing the cost, the efficiency of high voltage asynchronous motors with sinusoidal hard windings is enhanced further, which is feasible and very valuable for developing high voltage and high efficiency motors.
