Beneath Broken Machines is a cup of cold water to a dry, parched, and weary soul. In ministry, its easy to portray that I ONCE was lost...but now Ive got it all together. PC writes this book with humility and openness, which gives permission to confess that your machine is broken as well. - Travis Osborne, Pastor at Vintage Faith Church in Santa Cruz, CA As someone who has left the church, this book spoke to me. Im not talking about an awakening with pomp and circumstance, but something more simple, beautiful, and powerful. PC has always been a guiding force in my life, and this incredibly powerful book is no different. - Kyle Lacy, 3x Author and National Speaker We have a propensity to build machines out of our faith. We like to put in the right things in hopes it will churn out the right product. We become proud of the manufactured machines of faith we have built. The troubles with machines are they have no hearts and they break down. If your machine has broken down, you may have no idea what to do. Embark on a search for the heart that still beats for you. Embrace the wonder and awe of the ridiculous love of God that has always been for you. Encounter the heart of the gospel, which is the heart of Jesus beneath all of your pain, failure, and shame.

Fault Diagnosis, Prognosis, and Reliability for Electrical Machines and Drives An insightful treatment of present and emerging technologies in fault diagnosis and failure prognosis In Fault Diagnosis, Prognosis, and Reliability for Electrical Machines and Drives, a team of distinguished researchers delivers a comprehensive exploration of current and emerging approaches to fault diagnosis and failure prognosis of electrical machines and drives. The authors begin with foundational background, describing the physics of failure, the motor and drive designs and components that affect failure and signals, signal processing, and analysis. The book then moves on to describe the features of these signals and the methods commonly used to extract these features to diagnose the health of a motor or drive, as well as the methods used to identify the state of health and differentiate between possible faults or their severity. Fault Diagnosis, Prognosis, and Reliability for Electrical Machines and Drives discusses the tools used to recognize trends towards failure and the estimation of remaining useful life. It addresses the relationships between fault diagnosis, failure prognosis, and fault mitigation. The book also provides: A thorough introduction to the modes of failure, how early failure precursors manifest themselves in signals, and how features extracted from these signals are processed A comprehensive exploration of the fault diagnosis, the results of characterization, and how they used to predict the time of failure and the confidence interval associated with it A focus on medium-sized drives, including induction, permanent magnet AC, reluctance, and new machine and drive types Perfect for researchers and students who wish to study or practice in the rea of electrical machines and drives, Fault Diagnosis, Prognosis, and Reliability for Electrical Machines and Drives is also an indispensable resource for researchers with a background in signal processing or statistics.

Induction Machines Handbook: Transients, Control Principles, Design and Testing presents a practical up-to-date treatment of intricate issues with induction machines (IM) required for design and testing in both rather constant- and variable-speed (with power electronics) drives. It contains ready-to-use industrial design and testing knowledge, with numerous case studies to facilitate a thorough assimilation of new knowledge. Individual Chapters 1 through 14 discuss in detail the following: Three- and multiphase IM transients Single-phase source IM transients Super-high-frequency models and behavior of IM Motor specifications and design principles IM design below 100 kW and constant V1 and f1 IM design above 100 kW and constant V1 and f1 IM design principles for variable speed Optimization design Single-phase IM design Three-phase IM generators Single-phase IM generators Linear induction motors Testing of three-phase IMs Single-phase IM testing Fully revised and amply updated to add the new knowledge of the last decade, this third edition includes special sections on Multiphase IM models for transients Doubly fed IMs models for transients Cage-rotor synchronized reluctance motors Cage-rotor PM synchronous motor Transient operation of self-excited induction generator Brushless doubly fed induction motor/generators Doubly fed induction generators with D.C. output Linear induction motor control with end effect Recent trends in IM testing with power electronics Cage-PM rotor line-start IM testing Linear induction motor (LIM) testing This up-to-date book discusses in detail the transients, control principles, and design and testing of various IMs for line-start and variable-speed applications in various topologies, with numerous case studies. It will be of direct assistance to academia and industry in conceiving, designing, fabricating, and testing IMs (for the future) of various industries, from home appliances, through robotics, e-transport, and renewable energy conversion.
