    Sammanfattning : The use of variable frequency drives in centrifugal pump applicationshas raised the question of how to select a drive. Clogging obstacles inwaste water applications create unknown transient loads for the pumpsystem. A sudden load increase occurrence can clog the pump if thedrive cannot supply enough current to reach the motor’s torque demand. LÄS MER
