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
