    日本电产(尼得科)推出搭载有铝笼的高效同步磁阻电机“SynRA” ―达到国际能效标准中最高能效等级IE5水平―

    日本电产(尼得科)面向美国市场推出了将笼式感应电机的基本原理与同步磁阻电机结合而成的、搭载了铝笼的高效同步磁阻电机“Synchronous Reluctance Motor with Aluminum Cage Rotor)”。

    笼式感应电机为工业领域中常见的通用电机,这种电机的优点是接入商用电源即可起动且无需配置逆变器来控制转数,广泛应用于风扇和泵、空气压缩机、起重机、电梯等工业设备。此外,只要配置简单、价格低廉的V/F转换器*1即可满足变频式空调、家电产品等可变速的需求。因此,笼式感应电机被广泛用于定速、可变速的各种应用场景。而另一方面,由于笼式感应电机在结构上,转子和定子之间会产生被称为“滑差”的转速差(损失),因此与下文介绍的同步磁阻电机相比具有能效较低的缺点。
    “SynRA”通过对转子进行特殊的磁阻设计,纳入笼式诱导电机的“笼子(cage)”结构,在设备起动时
