厦门鑫永元机电设备有限公司

    IEEE的英文全称是the Institute of Electrical and Electronics Engineers（美国电气电子工程师学会），其前身是成立于1884年的美国电气工程师协会(AIEE)和成立于1912年的无线电工程师协会(IRE)。1963年，AIEE和IRE宣布合并，电气电子工程师学会（IEEE）正式成立了。

    IEEE-841是针对石油和化学工业或其它严苛用途电机的制造标准, 主要适用于高效(NEMA Premium)、全封闭风扇冷却(TEFC)、单速、多相鼠笼式感应电动机，1~500HP, NEMA机座143T以上。

    TECO东元电机的AEHH8B系列低压电机符合新的IEEE 841-2009版要求，符合UL和CSA安全认证。
