The modulating linear motors with integrated safety provide varying gas flow control instead of straight on-off control. By incorporating the device into furnaces and other types of gas-burning products, gas flow can be controlled and dispensed in varying amounts so that fuel is burned at a slower or faster rate as needed.
The P-Series line of variable frequency drives (VFDs) has been enhanced with a new redundant VFD unit. The Redundant Drive Panel (RDP) is designed to provide an economical HVAC motor control solution that maintains full control of an application if the primary drive fails.
The National Electrical Manufacturers Association (NEMA), its members who manufacture motors, and several other groups have filed a petition with the U.S. Department of Energy (DOE) recommending both new and more robust energy efficiency standards for electric motors used in commercial and industrial applications.
While shortening the iBLDC™ (Intelligent Brushless DC) motors with integral four-quadrant speed controls in the 45-mm frame size by 25 percent, the new size of motor maintains the same power and torque capabilities and motor efficiencies, said the company.
Although overall standards of refrigeration maintenance remain high, at many facilities there is still room for improvement. Upgrading your company’s rotating-equipment maintenance procedures and eliminating unsound practices will help reduce the risk of failures that can lead to process shutdowns or spoilage of refrigerated product.
Delivery and set up of 15 new motor drives and PLC (programmable logic controller) interface systems has been completed at MATC’s Industrial Automation Laboratory by ABB.
The split universal mounting kit version, Split uKIT, of the AEGIS® SGR bearing protection ring protects the bearings of variable-frequency drive motors from electrical damage, and allows quick and easy retrofitting of the ring on virtually any ac motor shaft without decoupling attached equipment.
In this month’s troubleshooting situation, we have a customer who has called to say that their condominium has no heat. The particular equipment in this case is a thru-the-wall package unit that provides cooling in the summer and employs a natural gas system to heat the building in the winter.
Driven by variable-frequency drives, the Gen2.0 PremiumPlus+™ brushless permanent magnet motors have motor-only rated point efficiencies of 93 percent and 92 percent for 3- and 5-hp versions respectively. They are packaged in standard NEMA frame sizes and mounting dimensions for easy substitution.
