摘要
三相绕组磁势中所包含的高次谐波的强弱直接影响电机的性能。采用低谐波绕组可以加强基波磁势,削弱5次、7次等一系列谐波磁势。由于磁势曲线中一系列高次谐波被消除(或显著地削弱),因而可以提高电机的出力(或降低温升),减少振动和噪声。
The strength of high order harmonic compo- nent contained in the three-phase winding magnetic poten- tial had a direct impact on the motor performance. The use of low harmonic winding could strengthen the fundamental magnetic potential and weaken a series of fifth and seventh harmonic magnetic potential. Because a series of high order harmonic in magnetic potential curve had been eliminated (or weakened significantly), the motor output was thus enhanced (or the degree of temperature rise was reduced), while the vibration and noise was reduced.
