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 [...]
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 [...]
DC drives are utilised in a variety of both commercial and industrial applications, which include processes such as rolling mills, printing presses, and elevators. When operating as it is supposed to, DC drives not only use energy more efficiently, but also provide better process controllability than their electromechanical counterparts. DC drives are known to present [...]
In order to offer a wider range of fieldbus options and systems capabilities, Parker made the decision to extend its range of add-on expansion modules for its 690+ AC drive range. Users are provided with a simple way to customize a base product to meet their exact requirements; this is possible because the expansion modules [...]
It is of the utmost importance that you understand that the AC drive does not produce any torque; it does in fact not even produce one ounce of load moving torque. All the mechanical force that moves your equipment and all of the mechanical force that is produced by the motor and drive system is [...]
Traditionally, AC drives have primarily been used in applications like conveyors, fans, and powering pumps. While their use in those applications will continue, it is a fact that the end-users of today have a different approach to that of a few years back.
AC drives are now fully developed and thus more widely accepted as a [...]
Simplicity and ease of use manifest themselves in many ways. The same applies to AC drives, and the way they facilitate the quest for miniaturization. The fact that AC drives can be used in domestic washing machines, to name one example, is a testimony to their extreme compactness. Over the years, AC drives have become [...]
AC drives incorporate safeguard function indicators which usually include motor overload, overheat, overcurrent, undercurrent, phase loss, as well as ground fault protection. The more modern AC drives used nowadays have the ability to provide up to 150 percent starting torque without requiring the overload protection necessary in many eddy current operations. What’s more is that [...]
A new range of AC drives was recently launched by Parker Hannifin. These new AC drives will enable permanent-magnet motors to be used in a wide range of compressor applications, fans, and pumps. The new AC650S Series eliminate the need to run permanent-magnet motors with closed-loop speed sensors, and also enables them to be used [...]
During its early years in the 1960s, AC drives had rather small solid-state components; this meant that the amount of current AC drives could supply to the electric motor was quite limited. This usually limited the size of the electric motor that could be controlled by a frequency and they were not commonly used. However, [...]
