How to Create a High-Resolution Time-Lapse segment
Tools needed:
Digital Camera and remote control
Camera-Controlling Software (optional but recommended)
Advanced Batch Convert (ABC)
Apple Quick Time Pro (QT)
Digital Video Conversion Software (e.g. Ulead Video Studio, Canopus, Adobe, Pinnacle)
Procedure:
Camera
Basic:
Choose subject matter (e.g. clouds) and depress remote button at regular intervals (e.g. every 10 sec.) for a certain length of time. Exactly […]

Can servos be used to dramatically reduce maintenance costs?
This article from Control Design suggests the answer is a
big “yes”:

Summary:
K.I.S.S (keep it simple, stupid) — basically, the less
mechanical parts, the better. “R.A. Jones has been building
cartoner packaging machines for 100 years. In its new
cartoner machines, the company changed over to servo drives
to reduce the number of […]

What are the consequences of operating an electric motor,
say 4.0 MW 11 kV delta connected, at 6.6 kV keeping the same
delta configuration? It is understood that the 4.0 MW motor
is not provided with six leads at the terminal box.
It is also understood that as long that the I_max of the
motor is not exceeded, there is […]

An engineer can protect against consequences of failures,
not necessarily failure mode.
In many cases failure modes are very difficult to define if
they are not specifically wear, fatigue, erosion or some
more obscure ones as in this list:
Wear
Fatigue
Erosion
Corrosion
Fretting
Impact
Stress Rupture
Fracture
Galling
Seizure
Spalling
Buckling
Yielding
And of course, combinations of these.
What to do:
Focus on cause of failure, define mode if possible, and be
certain to
define failure […]

Say you have new 24-volt DC motor that came with no manual;
it also has no data plate. It only has “Made in China”
stamped on one end of the chassis. You need to rate this
motor for UL approval. Your company actually needs a generic
testing procedure to determine the horsepower rating. How
ican this be done?
Here are some […]

Load cell sensors are used in industrial scales and weighing
systems. Examples include truck scales (used to weigh the
amount of material a truck is hauling), hopper scales (used
to measure the amount of material in a hopper) and tank
scales (used to measure the amount of liquid in a tank
vessel). In the case of truck scales, the weight […]

AC motors are more widely used than DC motors in industrial
applications. They are available to operate on single-phase
or three-phase supply voltage systems. This allows the
motor-control designer to choose the type of motor to fit
the application. Most single-phase motors offer less than 3
HP; larger ones are not that common. Three-phase motors are
available up to several thousand […]

Identifying the equipment boundaries assures we do not miss
anything in analysis and troubleshooting. For example, for a
pump the boundary could be:
. Motor mounting or flange (excluding motor)
. Coupling
. Discharge flange
. Inlet suction flange
. Pump and its mount
A motor boundary could include:
. Electric motor and motor shaft excluding the coupling
. Power cables up to the load […]

What standard need is one doing the FMEA for — 6 sigma,
RCM, RCA, other?
Start with reasonable and defined functions. (examples are
not a good plave to start)
Functions:
1. compress gas to 1500psi
2. allow expansion @X bar
3. radiate/ transfer heat degrees per __
4. contain gas 1200 to 2000psi
Failures:
1A. no compression
1B. not enough compression
1C. too much compression
EFM (mode + […]

EMC is the situation in which electrical and electronic
devices and systems work as intended, both within themselves
and in their electromagnetic environment.
Electromagnetic interference (EMI) is said to exist when
unwanted voltages or currents are present so that they
adversely affect the performance of a device or system. Such
voltages or currents may reach the victim circuit or device
by conduction […]
