Motor drives are a ubiquitous technology for transforming the constant voltage from the main ac power supply into a voltage that varies to control motor torque and speed ideal for motors that are driving mechanical equipment loads.
The electrical power issues that most frequently affect industrial plants include voltage sags and swells, harmonics, transients, and voltage and current unbalance.
Seeing a motor’s heat signature under normal operating conditions—with at least 40 % of design load—can tell you a lot about its condition.
Watch the video to see how the Point Defiance Zoo and Aquarium uses the Fluke 438-ii power quality analyzer and motor analyzer to reduce water and energy use.
Bob Despres of Jacobs Vehicle Systems® in Bloomfield, CT shares how he stepped up the motor maintenance program to be more proactive.
Discover how the Fluke 438-II Power Quality and Motor Analyzer can play a key role in maintenance programs.
This article demonstrates how to detect the 13 most common causes of winding insulation and bearing failure in advance.
How to measure output voltage from a VFD to a motor
Information on the role of thermal imagers in preventive maintenance programs, including cost savings, return on investment (ROI), and the inspection process. Included are common examples of infrared camera applications.
Motors and drives, the key components of any facility, are used everywhere and can be prone to a number of unseen problems.
Fluke MDA-550 Motor Drive Analyzer provides clear diagrams of the proper setup, pre-defined test procedures and step-by-step instructions to save time and help streamline troubleshooting elevator motor drives.
This application note explains how to use the MDA-550 Motor Drive Analyzer and a shaft voltage probe to measure motor shaft voltage discharge events.
Troubleshooting premature motor failures
Managing VFD voltage with a shaft grounding kit to detect shaft currents and eliminate downtime for customers, with a Fluke ScopeMeter™ oscilloscope
Monitoring power quality parameters in a variable frequency drive or uninterruptible power supply, can help to maximize performance. Find out how to determine what power quality parameters to measure and when as well as other associated issues such as harmonic currents.
In the past, motor repair meant dealing with traditional three-phase motor failures that were largely the result of water, dust, grease, failed bearings, misaligned motor shafts, or just plain old age. But motor repair has changed in a big way with the introduction of electronically controlled motors, more commonly referred to as adjustable speed drives (ASDs).
Preventing machine failure by detecting the first signs of trouble
There's an old saying that the first time you hook up a three-phase motor it will run backwards. If you're lucky, it will only make you look foolish. If you're not, it could severely damage expensive equipment and cost you or your employer substantial money.
Predictive maintenance (PdM) programs monitor equipment condition, with the goal of identifying problems in advance and avoiding equipment failure. One powerful tool for monitoring rotating equipment is thermal imaging.
Here we look closely at the first segment in a typical three-phase motor and drive system: from the mains supply at the drive input to the drive itself, concentrating on input measurements. This application note maps common problems to the measurements used to diagnose them . We show you what tools to use for a given situation and how to apply them to a problem, to enable you to troubleshoot more quickly and accurately.
Troubleshooting motor and drive problems such as single-phasing (losing one of the phase voltages) and flashover currents to outer bearings.
Four must-have measurement practices for the mechanical maintenance team: thermal, vibration, insulation, electrical
Fluke 1587 Insulation Multimeter helps keep 1950s motors and generators running into the 21st century
MetalTech produces steel sheets. Maintenance technicians use the Fluke 1587 Insulation Multimeter to troubleshoot and maintain the equipment.
Most problems with single-phase motors involve the centrifugal switch, thermal switch, or capacitor(s). If the problem is in the centrifugal switch, thermal switch, or capacitor, the motor is usually serviced and repaired. However, if the motor is more than 10 years old and less than 1 HP, the motor is usually replaced. If the motor is less than 1/8 HP, it is almost always replaced.
