The majority of shaft failures are caused by a combination of various stresses that act upon the rotor assembly. As long as the stresses are kept within the intended design and application limits, shaft failures should not occur during the expected life of the motor.

Electrical Advanced-Level Training
Introduction:
This training is recommended for inspectors performing component design bases inspections (CDBIs) or other detailed inspections of electrical systems. Inspectors with demonstrated experience may be grandfathered in the completion of this training, if approved by the division director.
Completion of technical proficiency-level training (Appendix C in IMC 1245) is strongly recommended before beginning this training. You may complete the requirements in this training standard along with the general proficiency requirements contained in Appendix B and
the technical proficiency requirements in Appendix C.
Objectives of Advanced-Level Training This training focuses on the activities necessary to fully develop individuals as lead or “experts” in the electrical inspection area. It is not the intent that all certified inspectors will complete all of the ISAs in this advanced appendix. In addition, this appendix should also be viewed as an inspector’s aid and could be used during an inspection to assist in inspecting a particular area.

Design Calculations for Electrical Design
Introduction:
Design calculations establish minimum guidelines and requirements for generating electrical calculations on projects. Electrical calculations should be made for all SPU projects that include electrical components and should be filed in the project notebook. Design calculations may be made either manually or by SPU-approved computer programs

Process Automation In Wastewater Treatment Plants: the Finnish Experience
Abstract:
The degree and importance of automation at municipal wastewater treatment plants (WWTPs) have increased with the development of technology and tightening of treatment requirements. The objective of this paper is to assess and document the current status of process automation at WWTPs in Finland to determine successful practices and the needs of plant operators. Renewing ammonia or organic content
removal processes to total nitrogen removal processes has also increased the need of Instrumentation, Control and Automation (ICA). The survey has quantified that the reliability and accuracy of the on-line sensor measurement has improved recently, which makes the use of on-line measurements in control more applicable. The use of nutrient sensors in control is apparently still rare at Finnish WWTPs even though their use for monitoring purposes is common.

Energy Efficient Electric Motors Systems
Introduction:
This manual gives a brief description of state-of-the-art technologies used to develop high efficiency motors, including premium efficiency induction motors, permanent magnet motors, and switched reluctance motors.
It also analyses issues that affect motor system efficiency and provides guidelines on how to deal with those issues namely by:
Selection of energy‐efficient motors
Properly sizing of motors;
Using Variable Speed Drives (VSDs), where appropriate. The use of VSDs can
lead to better process control, less wear in the mechanical equipment, less
acoustical noise, and significant energy savings;
Optimisation of the complete system, including, the distribution network,
power quality and efficient transmissions;
Motor Systems Energy Assessments
Taking Measurements
Applying best maintenance practices.
Motor Repair
How to win approval for energy efficiency projects
