The Key Differences between AC and DC Drives
While AC and DC drives each have specific uses, which is best for your project? In order to make this decision, one must first understand the benefits of each type of drive. Today AC drives are used much more frequently because of the precision that can be obtained from driving motors with them. Should you be looking for raw power, DC is the best choice. Let’s review the advantages and most common uses for each drive to understand how to identify drive solutions for your application.

Drive Solutions: Preventative Maintenance for Variable Frequency Drives
Variable Frequency Drives (VFDs) can extend the life of your motors, but how can you extend the life of your VFD? The most expertly specified VFD is only as useful as its operational reliability. This guide reviews variable frequency drives basics of care to ensure long-term productivity and cost-effectiveness.

Drive Solutions: What is a Line Reactor?
A line reactor (also referred to as a “choke”) is a variable frequency drive (VFD) accessory. It consists of a coil of wire that forms a magnetic field as current flows through it. This magnetic field limits the rate of rise of the current, thus reducing harmonics and protecting the drive from power system surges and transients.
Who Consistently Rolls Out the Most Dependable DC Drives?
Premier Automation answers with Siemens and their Next Generation of DC Drives Technology.
The SINAMICS DCM.
The SINAMICS DCM is the newest member of the SINAMICS DC drives family, combining the advantages of its predecessors, the SIMOREG 6RA70 DC Master, and the SIMOREG 6RA24 with the advantages of the SINAMICS family. Many of the SINAMICS tools and components so successful in S120 AC technology are now made available for the 6RA80 SINAMICS DC drives.

Understanding Variable Frequency Drives
Variable frequency drives (VFDs) are used to control the speed and torque of three phase AC induction motors. VFDs also provide start, stop, acceleration, deceleration, and direction control. There are a lot of factors to take into consideration when selecting a drive. Understanding the application, control, feedback, and operational environment is crucial to ensure that your drive application solutions are the right solutions.
