BP4-08006/04525频敏变阻器是一种有独特结构的新型无触点元件。其外部结构与三相电抗器想似，即有三个铁芯柱和三个绕组组成，三个绕组接成星形，并通过滑环和电刷与绕线式电动机三相转子绕组相接。
频敏变阻器是一种由铸铁片或钢板叠成铁心,外面再套上绕组的三相电抗器,接在转子绕组的电路中,其绕组电抗和铁心损耗的决定的等效阻抗随着转子电流的频率而变化. 本公司专门从事各种电动机起动设备的开发、生产、销售。公司自创建以来，始终恪守“以科技为先导，以质量求发展，让客户更满意”的方针，不断开发高、精、尖的科技新产品，不断扩大产品领域。本公司拥有先进的工艺，完善的检测设备及一支高素质的职工队伍，实施设计研制、加工制造和售后服务一条龙管理体系,
