Planetary Gearheads Suit Harsh Environments

Heason Technology has introduced the Aquatrue range of all stainless steel, washdown-grade planetary gearheads from its manufacturing partner Thomson. Aquatrue is designed for high-precision positioning in wet-cell processing applications in food and beverage, chemical and pharmaceutical production, caustic cleaning and other harsh-environment areas where frequent high-pressure spray or corrosive environments would reduce the life of standard-grade gearboxes The low-backlash gearboxes have a precision of 13 arc/min, four nominal frame diameters from 60 to 160mm, output torque to 875Nm and ratios from 3:1 to 10:1.

With high radial and axial load capacity and efficiency to 93 per cent, the Aquatrue design includes silicone gasket sealing and is supplied with IP66/67 or optional IP69K for total protection against close-range high pressure spray. The 304 grade stainless housings have no external seams or corners that can harbour dirt or bacteria. This protection eliminates the need to provide additional enclosures to isolate the gearhead in harsh-environment applications. Heason Technology also supplies a range of washdown- and food-grade servomotors from its distributor partner Kollmorgen, a sister company to Thomson. Part of the Kollmorgen AKM range, these precision servomotors include IP67 sealing with a 2K polyurethane external coating for maximum protection against alkaline and acid solutions, in addition to stainless-steel hardware on all precision surfaces.

Washdown- and food-grade versions are available in motor-frame sizes two through six, with output torques up to 25Nm. Heason Technology claims they are a cost-effective solution for motion control in food and beverage production, packaging machinery and many other applications where washdown is essential. The AKM range has BISSC (US Bakery Industry Standards Committee) certification, and is available in 90VDC and 180VDC in 1/4 and 1/2 HP ratings and speed to 1,750rpm.

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.
