Dynamic Balancing Machine model FBM
(M) is hard bearing type horizontal two plane dynamic Balancing machine
with microprocessor based measuring panel. Machine Model FBM (M) is
most suitable for balancing of different types of rotors like rotors
of eletrical machines, fly wheels, crankshafts cylinders, submersible
pump rotor etc. |

Applications
|
The balancing machines are meant for evaluating the
unbalance in a rotor. In Dynamic Balancing machine, the rotor is supported
by 2 sets of bearings and is run by a suitable drive.
The unbalanced centrifugal forces on the bearings are measured by
Sensors and are related to the unbalance in the rotor by a measuring
instrument.
These machines are used for balancing any rotating part which needs
dynamic balancing like electric motor armature, fan impellers, blowers,
etc. |
