Robert Rosenberg's Electric Motor Repair is widely considered the authoritative "bible" for technicians and trade students specializing in the winding, repair, and troubleshooting of AC and DC motors. First published in 1946, the book is famous for its unique double-spiral binding, which allows it to lie flat on a workbench with text on one side and corresponding illustrations on the other for easy reference during hands-on work. Key Technical Coverage
Motor Components: Detailed breakdowns of essential parts like the stator (stationary), rotor (rotating), end plates (brackets/bells), and centrifugal switches.
- Scope and purpose: The text is a hands-on manual focused on troubleshooting and repairing AC and DC motors used in industrial settings. It emphasizes practical procedures over deep theoretical derivations.
- Structure: Organized into chapters covering motor fundamentals (construction and operation), diagnostic testing (insulation tests, winding resistance, megger, hipot), mechanical elements (bearings, shafts, couplings), electrical repair (rewinding, insulation replacement, coil repair), installation and alignment, and preventive maintenance.
- Key techniques: Detailed step-by-step procedures for testing with common instruments, performing winding resistance and insulation measurements, interpreting test results, and performing safe disassembly and reassembly. The book outlines proper use of tools like megohmmeters, surge testers, and growler testers.
