三相HB型1.2°的步进电机，六主极无微调，与12主极有微调的全步进驱动时的位置精度比较如下图所示：1/8细分驱动时的位置定位精度比较如下图所示：三相12主极微调结构步进电机全步进时，位置定位精度可以改善±2%以内。在细分时，微调结构精度提高近50%。细分步距角精度比全步距角运行的精度大。步距采用8分割时，步距角为1.2°/8=0.15°，以此作为控制计算基准，其精度值当然比全步距角时要高。三相HB型高分辨率电机的改善：三相HB型步进电机有2相1.8°的1/3，即0.6°的髙分辨率电机，由于驱动芯片可以在市场上买到，所以可以很容易地实现高精度位置定位。

This product is suitable for electronic computers with rated voltage of 500V or below, and cables for automatic connection, which have high re for protection. The k-type B low-density polymer with anti-oxidation property is adopted for the insulation of cable ground core. High insulation resistance, good voltage resistance, low dielectric coefficient and low dielectric loss temperature and variation of the medium can not only meet the re of transmission performance, but also ensure the service life of the cable. ? The cable is shielded for cross - circuit interference and external. The shielding re of cables are respectively adopted according to different conditions: the total shielding of the hinged cable, the total shielding of the hinged cable, and the total shielding of the hinged cable after the hinged cable is shielded. Shielding materials are round copper wire, copper belt, aluminum belt/plastic composite belt three. The insulating property of shielding pair and shielding pair. The transmission of the cable will not be affected if there is potential difference between shielding pair and shielding pair in use.
