WebApplications of variable frequency drive above 50Hz. As everyone knows, the rated voltage and current of a specific motor is unchanged. For example, the rated value of VFD and motor are 15kW/380V/30A, the motor can work above 50Hz. When the rotation speed is 50Hz, output voltage and current of VFD are respectively 380V and 30A. WebJul 7, 2024 · In short, a VFD translates one voltage and frequency to another to change motor speed without losing torque. A VFD drive system could be divided into three subsystems: An AC motor , most often a three-phase induction motor but sometimes a single-phase or synchronous motor. songs with unintelligible lyrics https://marbob.net
