Micro/Midimaster Drives

The MICRO/MIDIMASTER Vector products are frequency converters for the speed control of ac induction motors in the power range 120 to 75 W. They are compact in design to allow installation in the minimum possible space. They are usable in a wide range of applications - from automatic car wash machines to conveyers. Sensorless vector control allows the use of MICRO/MIDIMASTER in more demanding applications such as lifts, packing machines and industrial washing machines
