1.前言磁电机自从问世以来,由于体积小,重量轻,可靠性高,和蓄电池点火方式一样得到很高的评价。作为小型汽油机点火装置目前已得到广泛的应用。最初,仅从点火机能方面考虑在实际中应用磁电机。后来,随着有关技术,特别是材料的进展,除点火机能外,又使其具备照明充电机能,另外,在结构上则以补充发动机所需惯性力矩的外转子磁电机(即飞轮磁电机)为主。近年来,作为无需维护及减少排气污染措施的一环,点火装置的耐久性能稳定化是不可缺少的,所采取的措施是:(1)断电器的无触点化;(2)点火提前角用机械式调速器的改进或采用半导体控制的电子式点火提前角装置。
1. Introduction Magnetoelectric machines have been highly evaluated since the advent of small size, light weight, high reliability and the same as the battery ignition. As a small gasoline engine ignition device has been widely used. Initially, the magneto was actually applied only from the aspect of the ignition function. Later, with the progress of the relevant technologies, especially the materials, they were equipped with the lighting charging function in addition to the ignition function. In addition, the outer rotor magneto (ie, the flywheel magneto), which supplemented the inertial moment required by the engine, Mainly. In recent years, as part of the maintenance-free measures to reduce exhaust pollution, the durability of the ignition system is indispensable. The measures taken are: (1) non-contact of the breaker; (2) advance of ignition Angular mechanical governor improvements or the use of semiconductor-controlled electronic ignition advance angle device.
