电机额定电流法变频器。 

变频器容量选定过程，实际上是一个变频器与电机的佳匹配过程，常见、也较的是使变频器的容量大于或等于电机的额定功率，但实际匹配中要考虑电机的实际功率与额定功率相差多少，通常都是设备所选能力偏大，而实际需要的能力小，因此按电机的实际功率选择变频器是合理的，避免选用的变频器过大，使投资增大。对于轻负载类，变频器电流一般应按1.1N（N为电动机额定电流）来选择，或按厂家在产品中标明的与变频器的输出功率额定值相配套的大电机功率来选择 

主电

1）电源电压及波动。应特别注意与变频器低电压保护整定值相适应，因为在实际使用中，电网电压偏低的可能性较大。 

2）主电源频率波动和谐波干扰。这方面的干扰会增加变频器系统的热损耗，导致噪声增加，输出降低。 

3）变频器和电机在工作时，自身的功率消耗。在进行系统主电源供电设计时，两者的功率消耗因素都应考虑进去

体积小、容量大的驱动装置；磁铁电动机也正在开发研制之中。随着IT技术的迅速普及，变频器相关技术发展迅速，未来主要向以下几个方面发展： 

网络智能化

智能化的变频器使用时不必进行很多参数设定，本身具备故障自诊断功能，具有高稳定性、高可靠性及实用性。

目前市场上新型变频器都内置了接口，同时提供多种相互兼容的通信接口，支持多种通信协议，同时可以通过连接计算机，由计算机键盘来控制和操作变频器，并且可与多种现场总线进行联网通信， 可以实现多台变频器联动，甚至是以工厂为单位的变频器综合管理控制系统。
