Taschenbuch. Condición: Neu. Neuware - Can you trace a fault to its cause in three measurements instead of thirty Do you know why a motor that hums but will not turn is almost never mechanically jammed Could you say, right now, whether the overload relay on your machine is sized from the nameplate or from the code table, and why getting that backwards leaves a motor with no protection at all Most electricians learn motor control the hard way. One expensive failure at a time. At 3 a.m., with production stopped and nobody to ask. The gaps are always the same. A stop button wired so the seal in bypasses it, producing a machine that starts and cannot be stopped. A drive fitted to an old motor that destroys the winding in four months. A ground loop chased for days by replacing a transmitter that was never faulty. Nobody teaches these. You bleed for them. This book closes those gaps. Here is what you gain: - Walk up to a machine you have never seen and understand it. Read the diagram, trace the logic, and know what the circuit does before you touch a single wire.- Cut a four hour diagnosis down to twenty minutes. The half split method finds a fault among sixteen devices in four measurements. Point to point testing takes sixteen.- Stop replacing parts that were never broken. Learn the symptoms that name the fault before you pick up a meter, and stop paying for components that fix nothing.- Size any motor circuit with confidence and defend it. Conductors, overloads, breakers, and disconnects, calculated correctly and ready for an inspector.- Commission a drive without cooking the motor. Know the one setting that silently removes all overload protection, and the cable run that punctures a winding in months.- Recognise the shortcut that gets someone killed. Understand exactly why a touchscreen stop button is not an emergency stop, and be able to say why when a manager pushes back.- Get paid for what fewer people can do. Ladder logic, PLCs, drives, networks, and panel design are the skills that move you from wiring to controls.Every chapter delivers real worked calculations, practice problems with answers, and diagrams built for the bench.
