正压外壳/增安型无刷励磁同步电动机设计

Design on the Positively Pressurized Enclosure/Safety-increasing Type Synchronous Motor with Brushless Excitation

以一台为国外压缩机配套的TZYW/TAW7800-18/3250WTHF1正压外壳/增安型无刷励磁同步电动机为例,叙述了正压外壳/增安型无刷励磁同步电动机的防爆优越性,介绍了单支撑同步电机的设计关键点,以及与同类电机相比后该类电机的优势。

Taking TZYW/TAW 7 800-18/3 250 W THF1 positively pressurized enclosure/safety-increasing type synchronous motor with brushless excitation, which was used to equipped with a compressor from abroad, as an example, the advantages in the fields of explosion-proof of the positively pressurized enclosure/safety-increasing type synchronous motor with brushless excitation was described while key points in designing of the synchronous motor with single-supporting was introduced as well as the supe-riorities resulted from the comparison with the same kind motor.
