Descrizione dell’articolo da parte del venditore

Paperback. A VFD trip is not a diagnosis. It is evidence.When an industrial motor stops, overheats, loses torque, vibrates, or trips repeatedly, the visible alarm is often only the surface symptom. The real cause may be hidden in the motor cable, power supply, drive parameters, control wiring, grounding, braking circuit, mechanical load, feedback device, or machine process.VFD & Motor Control Failures is a practical engineering guide to diagnosing variable-frequency drives, industrial motors, and complete motor-control systems under real operating conditions.This book goes beyond alarm-code lists and generic troubleshooting advice. It shows how to collect evidence, interpret drive behavior, verify electrical and mechanical conditions, eliminate false assumptions, and prove the true root cause before replacing expensive components.Inside this book, you will learn how to diagnose: - Overcurrent, overvoltage, undervoltage, overload, overheating, and ground-fault trips- Motors that fail to start, accelerate poorly, lose torque, overheat, vibrate, or draw abnormal current- Loose terminals, damaged cables, phase loss, voltage imbalance, and incorrect motor connections- Parameter errors involving motor data, acceleration and deceleration ramps, control modes, current limits, switching frequency, and protection settings- DC-bus instability, braking resistor failures, regenerative energy, and trips during deceleration- Grounding, shielding, EMC, bearing currents, and long motor-cable problems- Digital-input, analog-reference, encoder, sensor, interlock, and communication faults- Mechanical overload, seized bearings, misalignment, damaged gearboxes, blocked pumps, and process-related failures- Intermittent faults that appear only under load, at high speed, during temperature changes, or in specific production cyclesThe diagnostic method is built around real maintenance work: Symptom identificationAlarm and event-history analysisElectrical and mechanical inspectionVoltage, current, insulation, resistance, temperature, and signal measurementsParameter verificationRoot-cause confirmationCorrective actionPost-repair testingFailure preventionRealistic machine-failure cases show how misleading symptoms can lead technicians toward the wrong component. Each case explains what failed, what evidence was collected, which assumptions were incorrect, how the root cause was proven, and how recurrence was prevented.This book is written for industrial electricians, maintenance technicians, automation engineers, commissioning specialists, service engineers, machine builders, and reliability professionals working with real machines and real downtime.Whether you are dealing with repeated drive trips, motor overheating, current imbalance, unstable speed, braking faults, wiring problems, communication loss, or a machine that stops without a clear reason, this book gives you a systematic path from alarm to evidence, from evidence to root cause, and from root cause to a reliable repair.Stop resetting faults without understanding them.Stop replacing drives, motors, and cables without proof.Diagnose the complete system.Book 1 of the Industrial Motor and Drive Diagnostics Series.
