本文提出了微电机的一种新绕组形式——谐波分布绕组。我们与一般做法不同,有意识地利用绕组产生的气隙谐波磁场,进行谐波补偿和逼近。多次应用证明,采用这种绕组形式,可使线性旋转变压器突破极限精度,并稳定在0级(±0.055％,±2′)以上,某些产品的线性精度甚至可达±0.02％,±45″。文中对这种绕组的理论和线性误差规律作了分析,并列出了产品试验结果。 This paper presents a new form of micro-motor windings - harmonic distribution windings. We are different from the general practice, consciously use the air gap harmonic magnetic field generated by the winding, harmonic compensation and approximation. Multiple applications prove that using this type of winding, the linear resolver can break through the limit precision and be stable at level 0 (± 0.055%, ± 2 ’), and the linearity of some products can even reach ± ​​0.02%, ± 45 ".The paper analyzes the theory of the winding and the law of linearity error, and lists the product test results.
