Being employed by either an engineering or industrial company, chances are that you will be quite familiar with mechanical engineering formulas with which to calculate motion control.  You will also agree with the fact that mechanical calculations form an integral part to size a servo system.  However, this is only one of several mechanical engineering [...]

Working within the industrial and/or engineering industries, you will be familiar with the term inertia, more specifically the formula with which to calculate inertia.  As such, you will know that the formula used to calculate inertia form a very important part of these industries.  It is not uncommon to utilize servo systems in extremely dynamic [...]

If you happen to occupy a managerial position within a large corporation, you will know that it is a rather big responsibility which rests on your shoulders.  The main reason for this being the case can be attributed to the fact that the decisions you make tend to have a direct influence on the welfare [...]

Those of you familiar with the industry will know that the first electric drive systems on the market were DC powered. Even though brushless AC motors have largely replaced them over time, there is most definitely still a need for DC drives in industry.
AC drives are used particularly in small-scale output (the opposite of [...]

When an electric current is applied to a conductor, a magnetic field builds around that conductor.  If another conductor is in close proximity so that the building magnetic field “cuts” through that conductor, a current of equal potential is produced with flow in the opposite direction of the original current.  This conductor is called the [...]

One of the main benefits of Parker’s torque motors is to help end users of heavy-duty industrial machinery replace traditional motors and gearboxes with a highly efficient direct-drive system.  Used in conjunction with Parker’s variable-speed drives, the torque motors are to be used with plastics and rubber extrusion machines, as well as with injection moulding, [...]

AC and DC electric motors were seen as the muscle of the industrial revolution.  Ironically, these electric motors are now also regarded as the smart muscle of the computer-controlled plant and commercial facility of the future.  The advent of powerful, reliable AC drives and DC drives is keeping AC motors and DC motors in the [...]

Both industrial and commercial businesses make use of AC drive and DC drive systems Â
for a variety of applications.  Some of the more common applications include blowers, fans, and pumps.  Newer applications include textile-fiber spinning machines, machine tools, extruders, hoists and cranes conveyors, and film lines.  Â
Due to the fact that many applications have unique characteristics [...]

When compared to DC drives, AC drives cause very few problems.  However, poorly designed applications do sometimes result in power line voltage distortions.  These voltage distortions can also cause problems for other equipment connected to the same power lines, subsequently resulting in erratic operation of controls, dimming of lights, and overheating motors operating across the [...]

Although new advances and technologies are nice, is it really necessary to replace all DC drives with AC drives?  Should one not rather select the most appropriate motor and drive solution for your particular application?  This is an important question being raised quite often about this topic.  Both DC drives and AC drives have their [...]
