TOP TEN OPPORTUNITIES
IN MOTOR SYSTEMS
|
10.
|
Motors that are not energy-efficient
|
|
10.
|
When the motor fails consider replacing it with an energy-efficient model
|
|
|
|
9.
|
Motors that have been rebuilt incorrectly
|
|
9.
|
A mis-matched bearing or the wrong wire can degrade motor efficiency and hasten repeat failure. In general, do not rewind Open Drip Proof (ODP) motors
|
|
|
|
8.
|
Motors that limit production quality or quantity
|
|
8.
|
Motor Systems can and should be problem free. Find and
fix the root problem.
|
|
|
|
7.
|
Critical production motors that are not standard NEMA
|
|
7.
|
Specify NEMA design motors when purchasing equipment if possible.
|
|
|
|
6.
|
Lightly loaded motors that have a poor power factor
|
|
6.
|
If the motor is loaded less than 25%, the power factor and efficiency will be very poor.
|
|
|
|
5.
|
Motors that are fed with voltage imbalance
|
|
5.
|
Voltage imbalance places extra stress on the motor and windings and hastens failure.
|
|
|
|
4.
|
Motor systems that are mismatched to the load
|
|
4.
|
Match the machine to the load and save 20-50%
|
|
|
3.
|
Motor systems that run when they don't need to
|
|
3.
|
Turn it off when it's not needed. Save 5- 30%
|
|
2.
|
Motors that are unreliable, or "need" soft starts.
|
|
2.
|
Downtime costs you money and credibility. Fix the problem instead of accepting it.
|
|
1.
|
Motors that overload unless the machine is throttled
|
|
1.
|
Modify the machine to match the flow and pressure that the process needs and save 20-50%.
