FB--515医用变频调速制冷电容启动电动机
 摘  要：医用制冷压缩机作为医用电冰箱的“心脏”，其驱动电机既要考虑到在压缩机壳内能长期稳定可靠地工作，又要同压缩机体达到最佳的匹配，从而提高压缩机的安全及性能指标，获取最大的利益。本文对制冷压缩机用单相异步电动机的设计、材料使用等方面进行了探讨分析，并对提高电动机效率以及减小噪声提出了相关建议和措施。随着电力电子技术的发展，变频技术日趋成熟。变频压缩机具有能够迅速﹑连续地提供制冷，提高效率，降低噪音，提高运行可靠性等优点,以成为新一带制冷设备的发展方向。所以在本文中也对变频技术在压缩机方面的使用进行研究。

FB-515 Medical use frequency conversion is it refrigerate electric capacity start design of motor rapidly to transfer
 ABSTRACT: Medicine uses refrigeration compressor as " heart "of the medical use refrigerator,It urges electrical machinery to consider that can be steady in a long-term in compressing the chassis that work reliably,And also reach the best match with compressing the organism ,thus improve the security of the compressor and performance index,obtain the greatest interests.Analyse the discussion in such as this text uses to the refrigeration compressor with the design , material of the single different step motor,And to improve motor efficiency and reduce noise get relevant suggestions and measures out of. With the development of electric and electronic technology,frequency conversion technology is becoming riper.There are the frequency conversion compressors rapidly.Offer refrigeration in succession,raise the efficiency,reduce the noise,improve such advantages as operation dependability ,etc,in order to become a new a developing direction with refrigeration equipment.So in carry on research to frequency conversion technology use from compressor too in the article originally.
 Keywords: Frequency conversion adjusts the speed; Refrigeration; Single different step motor
