Mag-Mate Interconnect Reduces FHP Motor Costs

Tyco Electronics has released the Mag-Mate insulation displacement crimp (IDC) interconnection system - a cost-effective interconnect for fractional horsepower (FHP) motor manufacturers. The product drives cost reduction, as the same part number qualifies for termination of both copper and aluminium magnet wires. Fabrizio Longo, Tyco Electronics' product manager, said: 'Many medium- and high-volume manufacturers of FHP motors for appliance, heating ventilation and air-conditioning (HVAC) equipment are evaluating a switch from copper to aluminium magnet wire to reduce raw-material costs.

'Copper contributes on average about 30 per cent to the overall production cost of an FHP electric motor. 'Switching from copper to aluminium conductors can also reduce transportation costs, as aluminium is about one-third of the weight of copper. 'Our interconnection system allows manufacturers to easily and cost-effectively bridge the transitions many are making from copper to aluminium magnet wires,' he added. Aluminium conductors have approximately 61 per cent of the conductivity and a small fraction of the tensile strength of their copper counterparts.

Handling properties also differ, as the softer aluminium lacks the resiliency of copper. The Mag-Mate IDC connector system compensates for these differences by providing a stable, long-term termination of aluminium magnet wire - possible because of two IDC slots that provide four gas-tight points of contact (two on each beam). The Mag-Mate connector system simultaneously terminates two magnet wires of the same size in one terminal. It uses IDC technology to reduce assembly costs by eliminating soldering or stripping.

The UL-recognised product terminates wire sizes ranging from 34 to 12AWG for maximum flexibility. Product offerings include multiple lead-wire attachment options and special versions that mate with Rast 2.5 IDC connectors. This product range also offers slim-line and mini solutions to meet the needs of customers with space constraints. Specific applications of the product include motor windings, coil and bobbin connections, transformer windings and lighting ballasts.

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.
