摘　　要：自动石英手表微型发电机的生产中，磁性测量是质量控制及提高的关键。该仪器使用一光感面为8×40（μm）2的磁晶体管，绘出类似微型电机多极转子磁产生的三维图，在对该测量雏型进行描述后，文章对Lavet60极磁体及Kinetron微型发电机14极转子的测量结果与理论值进行了比较。In the production of electrical micromachines of automatic quartz watch, quality controling and improving of megnetic field measurment is the important thing. And such mcasurer use a rnagnetotransistor with sensitive surface of 8×40(μm )2. It is possible to research threedimensional filed plots for magnetic production of multipole of micromotor. The article make measurement result versus theory for lavet 60 - pole magnet and 14 - pole rotor of kinetron micromotor after describe the raw material of measurer.
