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 [...]

When compared to previous drives, the latest AC890PX modular drives available from EP Normand have ratings of up to 400Kw.  These compact modern drive units are just 500mm wide, enabling them to be installed easily into the limited space available.  These modern drives use sealed plug-in modules for all major functions, which makes them easy [...]

DC drives fulfill the role of an interface between a controller and the DC motor.  It is important that the DC drive match the control signals (voltage and power levels) as well as the signal type (analog or digital).  The DC drive is responsible for producing power conversion, amplification, and sequencing of waveform signals.  Types [...]

Using variable frequency drives (VSDs) to retrofit pumps with is now a well-established practice, and one that should become even more so with energy costs constantly on the rise.  The potential for energy saving as a result of employing variable frequency drives is especially related to pump systems that are oversized.  Variable frequency drives can [...]

In order to select the best AC drives for a given AC motor, a complete analysis of application categories is required.  Multi-axis controllers are used to control and monitor multiple, independent axes of motion.  Motor speed controllers are application-specific and used to control machines such as conveyors.  Digital motion control hardware and software for the [...]
