Our
high-speed, turbo-machinery balancers are
elegantly simple in operation. Counterweighted
rotor assemblies mount permanently at balance
planes on the shaft. A smart controller senses
vibration and determines the best counterweight
position. Rotor assemblies move
electro-magnetically to their appointed places,
minimizing vibration in seconds.
Features & Benefits
- Balances-corrects multiple planes in
seconds while your equipment is running
- Dramatically reduces equipment
startup time
- Balances automatically or manually
- Reduces equipment wear and tear,
downtime and maintenance costs
- Diagnoses equipment vibration
response
- Makes different corrections above
and below critical speeds
- Retrofits in coupling planes where
field trim balancing often takes place
- Accesses vibration inputs from
existing monitoring equipment, e.g.
Bently Nevada
- Records all corrections
automatically
- Protects bearings, seals and other
components during ramp-up
The Controller
The EM-2000 controller automatically controls
and tracks all balancer operation. It senses
vibration, determines the optimum balance
corrections, and sends signals to the balancer.
The controller can also interface to the machine
control using either PLC I/O or an RS232 serial
port.
The Balancing Ring
The operation is elegantly simple. The
patented counterweight rotor assemblies mount
permanently to the spindle shaft or rear of the
chuck. A coil assembly mounts to the spindle
housing. When a balance correction is required,
power pulses sent to the coils
electromagnetically step the rotors to the
desired position in just a few seconds.
Non-Contact Power Transfer
Since the coils induce a magnetic field
across an air gap, contact is not needed between
the rotating and stationary parts. Therefore,
there are no traditional motors, gears, slip
rings or other wear parts — it is virtually
maintenance-free!
The Software
With our Control Interface for Windows™
software, you’ll have simple point-and-click
control of the balancing system and manual
control of the counterweight positions. This
easy-to-use software provides detailed data and
graphical displays that give you real-time
information about your equipment and its
vibration characteristics. You’ll have spindle
speed, synchronous vibration magnitude, phase
angle, counterweight positions, alarm and fault
signals right on your desktop.
