4. Energy Savings Opportunities
Why is it important?
Source: Department Of Energy (DOE - 1994)
Money, Lots of Money
>13.5m electric motors 1Hp or greater in US industrial process operations.
Industry spends >$33b annually on electricity for motor driven systems.
Industrial motors system electricity accounts for 24% of all electricity sold.
Our Environment
Industry consumed 691b kWh in process motor driven systems plus an
additional 68b kWh per year on HVAC.
In the US industrial sector, 70% of all electricity consumption involves
motor driven systems. 59% of this goes to pumps, fans, blowers and
compressed air systems.
Because we can make a difference!

5. Summary of Benefits
Energy Savings
kWh savings (especially variable torque loads)
Improve power factor – AC drives above 0.95 power factor
Reduce peak demand surcharges
Process Improvements
Match speed to need & eliminate the starts & stops
Maintenance
Less stress on mechanical equipment including belts &
couplings.
Controllable via a BMS, PLC or fieldbus (Ethernet, Metasys,
DeviceNet, Profibus, Modbus, & others).
Comfort
Reduced fan / pump noise
Reduce water hammer and air duct rumble
No light dimming on start up

6. Present Day Drive Shaft Issues
Inspect Drive Shaft and Coupling
Hardware Monthly
Inspect Coupling Flex Element for
Buckling and fatigue damage
Replace as Required
Each time a blade passes near an
obstruction, such as a drive shaft
or structural support the blade
load fluctuates
Drive Shaft Coupling
Baldor Solution Eliminates These Issues

8. Summary RPM-AC Direct Drive CT Motor
Laminated Frame Interior PM motor technology enables direct drive gearless
system.
Gearbox low speed lubrication issues are eliminated.
No drive shaft
No couplings
No guards
No alignment
Minimizes blade load fluctuation.
Motor can be configured / drop in replacement for gearbox
(Ref Clemson University Beta site)
Clemson was 6 hour conversion.
The Baldor Lamination Frame Technology / Interior Permanent Magnet
Design along with Magnet performance improvements have allowed Baldor to
lead with this new Innovative Disruptive Solution.

9. Summary (cont’d)
Vastly simplified system greatly improves reliability and
maintainability.
Significant improvements in overall system efficiency can
be realized.
Elimination of gearbox provides biggest improvement in
overall fan drive system efficiency.
Although a Baldor V*S drive is required, the majority of
cooling towers are being retrofitted with VFDs.
