Energy Savings OpportunitiesWhy is it important?

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!

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

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

Final Installation at Clemson University

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.

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. Ref ASHRAE Std 90.1 variable speed requirements

Direct Drive motor reduces noise level of cooling tower Elimination of drive shaft improves noise level.
