适用于低惯量感应电机驱动的基于直流信号注入的定子绕组电阻估计方法

Thermal protection is an important aspect that should be considered in ac machines to prevent reduction of the lifetime. For economic reasons, temperature estimation is preferable than the installation of thermal sensors. Thus, several proposals based on dc-signal injection have been reported. Their main drawback is that a certain torque ripple is produced during the injection. On the other hand, ...
