Penrose Lecture Series 2007
President, SUCCESS by DESIGN
One of my New Year Resolutions was to re-start the Penrose Lecture Series blog on electric motor systems.
Over the past year, things have been quite exciting. I fired my last boss and turned my small publishing company, SUCCESS by DESIGN, into a Reliability Services Consulting company. As the year progressed, I found myself busier and busier, then, we continued to grow with new clients and participation in shows, talks and the development of studies related to the industry. This also included taking the part in the creation of the Institute of Electrical Motor Diagnostics, Inc.
Now, SBD is growing and we are adding personnel during 2007, as well as expanding our services and offerings.
Towards the end of 2006, we started a series in Uptime Magazine that brought us back to basics starting with how to use a voltmeter, ammeter, resistance meter (January) and the February edition will be on the use of an insulation resistance (MegOhm Meter). We will be continuing the series all the way up to some of the electrical motor diagnostics technologies.
In this blog, we will cover general motor system information, test concepts, the Motor Diagnostics and Motor Health Newsletter, test processes and methods and any other topic of interest.
In the meantime, additional articles and materials have been added to the http://www.motordiagnostics.com/presentations.htm website and a new iPresentation on rotor bar testing has been added to ReliabilityWeb.com:
Evaluating Induction Motor Rotor Bars with Electrical Signature Analysis
An iPresentation Tutorial by Howard W Penrose, Ph.D., CMRP, SUCCESS by DESIGN Reliability Services
Electrical Signature Analysis (ESA) is one of the most accurate methods for the detection of broken rotor bars in operating induction motors. This 8 minutes iPresentation Tutorial will cover the forces acting on rotor bars that cause eventual failure, including the difference between cast and copper alloy rotors. It will then cover the most common signature for broken rotor bars and recommended alarm settings for single and multiple broken bars.
Which can be viewed at http://www.reliabilityweb.com/forms/tsol_reg.htm.
We look forward to helping you improve your motor systems in 2007.
