In accordance with recent changes in motor efficiency laws, it’s now mandatory that continuous duty motors for integral gearmotors be Premium Efficient. It’s important to recognize that this requirement only applies to continuous duty motors. Motors rated for intermittent operation (for non-continuous applications) are not required to be Premium Efficient. Premium Efficient motors have more […]

Ultra-efficient motors for low-speed direct-drive applications from NovaTorque
NovaTorque has introduced 600 rpm versions of its PremiumPlus+® Electronically Commutated Permanent Magnet (ECPM) Motors. The new 600-rpm versions are currently available from 0.75 to 3 hp, with 5 and 7.5 hp models coming soon. These versions are particularly well suited for directly driving larger diameter fans at low speeds, enabling the elimination of the […]
FAQ: When to pick a pre-engineered gearmotor and when to design your own?
Gearmotors are available in a variety of styles, packages, and options. There are two standard methods for picking a gearmotor. One is simply selecting a pre-engineered unit and the other is choosing a motor and gearbox separately and then assembling them into one finished unit. So the question is, when to pick a pre-engineered gearmotor […]
Compact, precision ring drive system from Nexen
Nexen Group, Inc. introduces the Compact Ring Drive (CRD) system with a precision grade bearing and drive mechanism in a sealed housing. Freely programmable, the three-drive design configurations allow the CRD to be optimized for high speed, high torque or both, depending on the application. With a 250 or 350 mm dial plate bolt circle […]

HEIDENHAIN debuts new angle encoder modules
HEIDENHAIN’s new product family is a merger of HEIDENHAIN bearing and angle encoder technologies. The new MRP 2000, 5000 and 8000 (as well as customer-specific variants) are unique modules containing bearing sets not conventionally available and are able to be integrated with various encoder types to yield highly stiff modules that are easy to install. […]
Schaffner introduces FN 5060 output filters for AC motors
New FN5060 dv/dt filters from Schaffner protect AC motors from destructive effects of peak voltages and inrush currents, increasing service life and system reliability. This patented technology protects motors and adjacent equipment without capacitors or resistors, making them simple to install. They efficiently reduce high output dv/dt from IGBT motor drives and eliminate over-voltages caused […]

FAQ: What is the Department of Energy’s new Small Motor Rule?
Large motors have been subject to energy efficiency regulations for quite some time. The U.S. began regulating energy efficiency of integral horsepower motors back in 1992 with the passage of the Energy Policy Act (EPAct). Subsequent updates to this original legislation include the EPAct in 2005 and the Energy Independence and Security Act (EISA) of […]
