Flexible rotors can be balanced efficiently.
High speed spindles, Turbo blowers, Cross flow fan, Drive shafts etc.
Flexible rotor which is very difficult to balance can be easily balanced by multi-speed multi-plane balancing algorithm.
Before high speed field balancing of assembly, each rotating components should be balanced by this balancing machine, then peaks of resonances can be suppressed.
Conventional balancing planes is up to 2 planes.
However, in case performing 2-plane balancing of rotary part of high speed rotary machine, check structure and shape of rotary part and select proper No. of Correction plane. Otherwise, it may cause higher order vibration of flexural mode under high speed rotation.
Sigma’s horizontal balancing machine expands No. of Correction plane until 4 planes at maximum, selecting proper No. of Correction plane freely. So the above mentioned problem can be solved easily.
