Regal Beloit Corp. announced that it has completed the acquisition of the RAM motor business previously owned by Schneider Electric. This business manufactures hermetic motors from 250 hp to 2,500 hp for commercial HVAC applications.
All major manufacturers of three-phase ac induction motors offer “inverter-duty” or “inverter-ready” models, but while these motors have inverter-rated insulation to protect the windings, the bearings — their most vulnerable parts — are too often ignored.
Four Regal Beloit Corp. divisions officially introduced a total of six new products at their exhibit (Booth 2301). Genteq launched Evergreen EM, the latest in its line of standard ECM replacement motors for the aftermarket/distribution market.
Bob and Tim arrived at their fifth service call of the day. They were both wet from servicing a heat pump outdoor unit in the snow. This was a no heat call for a gas furnace. The weather was cold and there was no heat at all in the house.
Titan HD Motor Run Capacitors have been carefully developed and tested to provide hardworking, reliable operation, the company says. This line of capacitors is made in the USA and offers up to 60,000 hours of operational life.
The split universal mounting kit version (Split uKIT) of the AEGIS® SGR Bearing Protection Ring is designed to protect the bearings of variable frequency drive (VFD)-driven motors from electrical damage,
Cerus Industrial’s P-Series Energy Management Bypass (EMB) is said to be a new approach to bypass design. It features integrated BACnet communications and ANSI-grade metering to +/-1 percent in both variable frequency drive (VFD) and bypass mode.
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.
