Low-Energy Motors for Energy-Efficient Machinery

Yaskawa has launched the EcoIPM series of low-energy motors, suitable for energy-efficient equipment and machinery in demanding working environments. When combined with a Yaskawa V1000 inverter, the EcoIPM permanent magnet motors form an efficient drive package that can help to reduce lifecycle costs. Under the EuP legislation, certain types of new equipment, such as pumps, fans and compressors, will have to meet efficiency requirements that can only be fulfilled by combining an IE3 motor with an inverter drive.

EcoIPM motors are claimed to offer better energy efficiency than standard motors. The permanent magnet motors are designed to optimise cost effectiveness and to help reduce carbon emissions through lower energy consumption when combined with a Yaskawa V1000 frequency inverter. With the EcoIPM motors, the company complies with the new EU directive (640/2009), which mandates that motors of the previous EFF2 efficiency class may not be sold from 2011 onwards. With energy prices going up steadily, inefficient types of equipment and machinery are becoming an increasing cost factor.

That is why, in the long run, companies can realise economical advantages by converting to EcoIPM motors in combination with frequency inverter-based speed control, according to Yaskawa. The resulting energy savings will cut down operating costs and the saving potential will increase as energy prices go up, added the company. In terms of lifecycle costs, the package combining EcoIPM and V1000 also delivers a range of benefits. The EcoIPM motor and the inverter both feature a compact design. The new motor is two sizes smaller than a level IE2 asynchronous motor.

The smallest member of the product range features a 56A frame size and the largest comes in a 90B frame size. The motors are available in B3 design and in flange-mount versions - both in 200V and 400V voltage classes. The V1000 inverter can control the EcoIPM without motor feedback, making the package suitable for demanding working environments. The inverters and motors are available for the European market and comply with European CE regulations. Yaskawa will present the new motor on Stand 320 in Hall B2 at Automatica.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
