Motors & Drives

Companies that upgrade their pumping systems, or install new systems, both with the objective of improving efficiency, commit themselves to substantial investment, not only in terms of the pumps themselves, but also with new energy efficient motors to drive them. However, these investments can easily be wasted if the pump/motor combination is not integrated in a way that not only maximises the respective pump and motor efficiencies, but also protects the combined equipment from normal wear and tear.

Teka, located in Blumenau in the state of Santa Catarina, Brazil, is one of the leading producers of bed, bath and table linens in South America. As part of its strategic planning, the company has developed two programs: the first concerns replacing burnt-out motors with high efficiency types; and the second, replacement of motors following power consumption audits.

WEG Middle East has successfully overcome a tough challenge to engineer and supply – at short notice – 250kW HGF motors to fit in the same space envelope previously occupied by three 132kW Loher pump motors, at the Daleel Petroleum Oil Field in, Oman. The ability of WEG to provide the motors and VFD drives – all with 3- year warranty - is enabling Daleel Petroleum to increase the output of three crude oil shipping pumps by 45% respectively; each pump now being capable of shipping 16000 bpd, instead of 11,000 bpd previously. This increase also offers the advantage of enabling one pump to be withdrawn at any time for maintenance, without Daleel Petroleum incurring penalties for falling below its contracted pumping rate of 30,000bpd.

“Mastering Cascade Control” has been released by PIDTutor. The book is designed to help technicians and engineers to implement and troubleshoot split-range control applications.

Ethernet Direct Corporation, a professional and primary provider of industrial networking and communication solutions, launches HMG-448GE-CD, an enhanced version of Industrial Managed Gigabit switch that comes with extended operating temperature of -40 to 80 deg C especially designed for mission critical applications like in military, power & utilities, mining and other areas with hazardous environments.

Ethernet Direct Corporation, a professional and primary provider of industrial networking and communication solutions, announces an expanded product offering of Whale series M12 IP67 Industrial Ethernet switches designed for the toughest industrial applications.

Ethernet Direct Corporation, shares a special application about wireless system in mobile base stations. In-car video surveillance systems are commonly installed in law enforcement agencies’ vehicles. In-car surveillance systems not only enhance officer safety, but also improve law enforcement agency accountability and reduce agency liability. Ethernet connections are used to transferring the video files stored in the hard disk installed in car to the control center.

The largest contributing factor to motor failure is excessive motor heating. The life of the motor is shortened if the winding temperatures are allowed to exceed their insulation class levels for a significant amount of time. It is usually assumed that, for every 10°C above the design temperature limit, life of the motor is reduced by a factor of two. Therefore, aggressive application of intelligent thermal motor protection must be implemented to get maximum return on these very large and very critical capital investments.

The latest range of P1V-A and P1V-B air motors from Parker Hannifin, the global leader in motion and control technologies, have been launched to provide an efficient and cost-effective alternative to conventional AC and DC devices. Based on a simple but extremely reliable design, Parker’s latest air motors are compact, lightweight and capable of providing an exceptionally long operating life. They have been developed for use in particularly demanding applications, including those where it is impractical or unsafe to use electric motors, and can play an important role in helping to improve the performance, productivity and profitability of a wide range of industrial and process machinery.

Since its launch in early 2009, Rotalink's Red Drive servo motor driver and controller has significantly lowered the cost barrier for brushed DC precision motion control. Now the innovative designer and manufacturer of miniature motors, transmissions and controls has launched a brushless version of Red Drive that offers the same easy-to-use flowchart based software and price-performance advantages of the brushed version. The new BLDC10A Brushless Red Drive has a 10A input current rating from a 12-24 VDC supply voltage and includes hall sensor inputs for brushless commutation, incremental encoder input and 27 programmable TTL level I/O pins for analogue and digital machine interfacing.
