皮带轮式永磁交流电机无电压调节装置,在最低、额定及最高工作转速时,其电压值应满足ZBT68004—90的要求。此文从永磁交流发电机的基本电磁关系出发,导出满足其电压要求时应具有的空载电势和同步电抗数值,并就每相串联匝数的确定及如何达到所需电抗值进行了探讨。最后通过试验对所得结论进行了初步验证。Permanent magnetic pulley alternator has no voltage regulating unit. Its voltage value should meet the requirments of ZBT 68004--90 at the minimum, nominal or maximum speed. According to the basic electromagnetic ralations of the permanent magnetic alternator, this article leads out the values of no-load potential and synchronism reactance necessary for meeting the voltage requirment. It also explores the determination of each phase serial number and attainment of the necessary reactance. At last,the conclusion resulted from the trial has been tested and verified primarily.
Pulley permanent magnet AC motor voltage regulator device, at the minimum, rated and maximum operating speed, the voltage value should meet the requirements of ZBT68004-90. Based on the basic electromagnetic relationship of permanent magnet alternator, this paper derives the no-load potential and synchronous reactance value that meet the voltage requirement, and discusses the determination of the number of turns in each series and how to reach the required reactance .
