Overview

Energy Efficiency Circle

Identify — Evaluate — Realize

A comprehensive approach

Continuous

Improvement

Process

Consistently increase the productivity of the energy applied

1 — Identify

Instead of reacting to more or less haphazardly

discovered energy guzzlers, the customer consistently

and permanently observes its energy fluxes.

2 — Evaluate

Interpretation and comparative analysis of all

energy changes to recognize potential.

3 — Realize

Optimizing energy consumption and monitoring results.

The result is that energy resources are controlled

transparently and effectively.

The Siemens approach to increasing energy efficiency —

Consistent and continuous improvement

VFDs and Energy Efficiency

1. Flow control optimization

and compressors using

mechanical flow control

2. Wasted energy recovery

o Cyclical applications

o Braking applications

• Holding Torque (regen)

applications

Why Use VFDs?

• Industrial electric motor-driven systems represent the

largest single category of electricity use in the country.

• Industrial electric motors represent over 65% of

power demand in industry.

• Motor-driven systems offer one of the highest potential

for energy savings in the industrial segment — 70%.

• Almost all motor lifecycle cost is expended on the

energy the motor uses (97-99%).

• Government incentives, utility rebates and savings-based

financing can provide low up-front investment and ROI in

as few as 3-6 months.

• Approximately 33% of industries report no improvements

for the pumps, fans, compressors in their facilities.

Benefits of Implementing

Energy Efficient VFDs

• Energy efficient VFDs save energy,

reduce utility bills, provide precise

motor speed control, improve overall

process control and reduce operating

and maintenance costs

• May require little upfront investment,

are easy to implement, and have

payback times of less than a year

• Energy efficient VFDs help reduce the

negative impacts on the environment

and can enhance corporate community

relations programs

Focus Areas for VFD systems in Motion Control

• Regenerative Applications (torque holding, braking) = Energy recovery and reuse

• Ancillary systems – fans, pumps, compressors

= Energy saved normally wasted via mechanical control methods (veins, throttles, dampers, etc.)

• Power factor monitoring and control

= Less energy consumption

• Control and monitoring systems - thin client control systems versus PCUs = Less energy consumption

• Optimized heat dissipation for power units = Less energy consumption

• Use of proper component sizing tools to avoid over sizing = Less energy consumption

• Mechatronic evaluation for optimized system efficiency = Les energy consumption and reduced system stress

Motion Control Presented by

Jesse Henson

Motion Control Sales Manager

Baldor Electric

‗Green‘ Motion Control • Induction Motor efficiency compared to PM Servo

• Impact of the Energy Independence and Security Act

• DC shared installation savings

• Trends using integrated motors and distributed power

• How Motion Controllers Save Energy

Today‘s Industrial Market Challenges to compete

• Reduce Manufacturing Cost

• Increase Through put

• Reduce Labor Cost / Content

• Reduce Energy Cost / Content

• Minimize waste

• Maximize equipment life

• Reduce downtime

• Increase Quality

• Remove things that are not productive

Energy Independence and Security Act Impact

• Automakers gas mileage to 35mpg by 2020

• 25% greater efficiency for light bulbs 2012 to 2014

• 1 – 200 HP general purpose motors (December 19, 2010) o 2, 4, & 6 Pole

o 230/460V

o 60Hz

o General purpose motors already covered by EPAct

• Change from MG-1, Table 12-11 to Table 12-12 Premium Efficient levels

o 201 – 500 HP will comply with Table 12-11

o Cabling

o Design Time

o Build Time

o Component Count

o Save Energy Cost

o Improved Reliability

o Less Panel Space

Filter

Today‘s typical Motion Control system

• Traditional Control cabinet takes up a lot of space

• Wires per motor from control cabinet to each motor

• Extra expense in panel wiring and cable routing

Integrated Motor Technology

• Less cabling

• Smaller control cabinet

• Reduction in assembly time

• Smaller machine footprint

Going ‗Green‘ with Motion Controllers

• Reduced carbon footprint

• Advanced diagnostics

• Reduced downtime

• Real-time Ethernet connectivity

• Complete machine visibility (Remote diagnostics)

• Energy to a motor only when needed

• Advanced software reducing mechanics on the machine

• Increased Productivity reduces cost

• Increased accuracy / reducing waste
