bars, excessive VFD drives on low voltage
busses and mechanical problems.
Torque (Optional)
The torque domain is a substantial break-
through by Baker Instrument Company,
an SKF Group Company. Torque Ripple and
Torque Spectrum enable the user to find
numerous problems quickly and
accurately. It specializes in diagnosing
mechanical issues, shows transient
overloading, finds mechanical imbalances
along with bearing problems, and
cavitation, among others.
Connections
This portion of the SKF Dynamic Motor
Analyzer - EXP4000 software offers
additional tools including phasor diagrams,
three currents and voltages, instantane-
ous voltage, and symmetrical components.
This data provides the operator with valu-
able power data as well as a way to make
sure the EXP4000 is correctly connected.
VFD monitoring (Optional)
Along with any three phase induction
motor and generator, the SKF Dynamic
Motor Analyzer - EXP4000 will monitor
the activities of VFD applications and AC
servo motors using the VFD4000 software
module. These types of drives have always
created problems for maintenance
professionals and for the first time
comprehensive diagnosis of motor
problems are facilitated even under the
most demanding VFD operation.
Continuous monitoring (Optional)
The continuous monitoring software
(CM4000) enables the user to monitor
41 data points real time. This real time and
continuous data gathering capability will
give immediate impact in finding
intermittent problems with motors such as
electrical tripping. This user customized
software enables the operator to collect
real time data on whatever is deemed the
most important to their operation. This
software will also act as a power analyzer
to determine actual power quality.
Transient Analysis
The SKF Dynamic Motor Analyzer -
EXP4000 also performs a start up analysis
using the transient analysis tool. The traces
are the rms currents and voltages of all
three phases. This data can be zoomed,
panned, and the cursors allow reading of
levels and time within the graphs. Along
with this powerful analysis capability,
startup Torque versus Time can also be
evaluated. These tools allow the user to
visually see the amplitude of voltage,
current and torque at startup, along with
motor startup time. Only by monitoring all
three phases of the current, voltage and
torque can the maintenance professional
separate between a power, motor or load
issue on start up.
Efficiency
Efficiency assessment, pay-back period
and Motor Master+ identify motors
performing under par, and calculates the
pay-back period if replaced by a new motor.
The SKF Dynamic Motor Analyzer -
EXP4000 exceeds the performance of
other instrumentation in both accuracy of
efficiency estimation and in ease of use for
field environments.
