  • Understanding Electronic Motor Drives
    Matching drive to motor is essential to gain the best combination of torque, speed, and efficiency. Drives & Power Products Group The ACS 160 drive from ABB is designed as a modular unit for both wall-mount and IEC motor-mount installations. The NEMA-4X (IP65) micro drive is suited for applications
  • The Next Generation of US Energy Efficiency Motor Regulations
    The U.S. efficiency regulations for industrial electric motors have been in place since October 1997 when the Energy Policy Act of 1992 (EPAct 92) set minimum efficiency levels for 1- through 200-horsepower (HP), general purpose three-phase motors. EPAct 92 was upgraded when the Energy Independence
  • Advanced Energy
    efficient electric motors. These motors have efficiency levels that carry the NEMA Premium TM label, a program sponsored by the National Electrical Manufacturer's Association (NEMA). NEMA is a voluntary group of electrical manufacturers that are recognized as North America's authority on motors
  • A Push Towards Efficiency
    Association (NEMA) unveiled its Premium efficient electric motor program in 2001. These motors exceed the minimum energy efficiency standards required by the Energy Policy Act of 1992. In addition, NEMA Premium sets efficiency standards for an increased range of motors. NEMA Premium efficiency may
  • Heading Off a Kilowatt Crunch
    . Under the old act, the energy-efficiency levels for induction motors were known as Epact levels and can be found in NEMA MG-1 Table 12-11. The new regulation restates the definition of General Purpose Electric Motors as defined in 10 CFR 431 from the Energy Policy Act of 1992 (Epact) and classifies
  • Medical Device Link .
    A line of all-stainless-steel motors, servomotors, and speed reducers is available from a US manufacturer of energy-saving industrial electric motors, drives, and generators. Stainless Super-E (SSE) motors from Baldor Electric Co. (Fort Smith, AR, USA) come in versions from 1/2 to 2 hp at this time
  • Improving Energy Efficiency in Pharmaceutical Manufacturing Operations Part I: Motors, Drives and Compressed Air Systems
    motors, meeting or exceeding performance criteria published by the National Electrical Manufacturers Association (NEMA), reduce energy losses through improved design, better materials, tighter tolerances and improved manufacturing techniques. Replacing an old, poorly functioning motor
  • Pneumatic or servo?
    approximately 30-lb continuous force to well over 4,000 lb. Linear-motor forces only range as high as 2,700 lb, but at significantly higher velocities. Rotary possibilities use carriage assemblies that contain small leadscrews with a rotary mount. When mated with NEMA-17 motors and indexers, these assemblies
