摘要：

To　obtain　the　stable　output　voltage,　a　new　type　of　MWD　hybrid　excitation　generator　is　designed　in　which　magnetic　flux　can　be　regulated　from　-2%　to　22%.　In　the　generator,　hybrid　excitation　part　and　permanent　magnet　part　work　in　parallel.　This　article　introduces　the　working　principle　and　structure　of　this　generator.　In　addition,　finite　element　analysis,　magnetic　field　and　regulation　characteristics　analysis　for　this　generator　is　addressed　to　illustrate　the　variation　of　magnetic　flux　with　pole　length　and　excitation　current　changing.　Experiments　verify　the　design　and　finite　element　analyses.　©　(2013)　Trans　Tech　Publications,　Switzerland.
