This paper introduces three kinds of hybrid excitation claw pole motor structure: Permanent magnet (PM) placed in the yoke (Model a), PM placed outer surface of the claw (Model b), PM between the claw (Model c).It analyze three kinds of claw pole motor on magnetic circuit and structure, then calculate electromagnetic characteristics of three kinds of structure with three-dimensional finite element...
Summary To clone and sequence the human tissue kallikrein gene of Chinese, and to construct eukaryotic expression recombinant of KK, total RNA was extracted from human pancreas and human tissue kallikrein gene cDNA was amplified by PCR after reverse-transcription by using Oligo(dT) primer. The original kallikrein cDNA was recovered and filled with Klenow enzyme and inserted into KS plasmid. After...
