Heavy-Duty Drives Suited to Process Applications

Advanced technology heavy drives are being custom engineered by Bonfiglioli for clean and robust service in applications where they are mounted vertically to aerate or mix liquids. One of the most recent of the locally engineered heavy-duty (HD) drives to be delivered this year integrates 55kW six-pole motors with HDP helical parallel series drives featuring dry well construction and a lubrication pump. The motors - specified for 55kW power and 10kNm output torque - incorporate the OP2 lubrication pump to ensure good bearing performance in vertical mountings.

They are also epoxy coated for corrosion protection, cleanliness and durability. The drives incorporate a dry well construction to safeguard against oil leaks into process liquids as seals age and wear. These particular drives were specified for aerators at a wastewater treatment plant, but many of the features apply equally well to other process applications involving food and beverage manufacturing or minerals processing liquids. For example, drive bearings are engineered to accept the greater loads generated when used on the long shafts found in aerators.

One of the flexibility features of Bonfiglioli's production and testing line for HD drives is that the company can adapt specific drives to particular applications. HD drive combinations are particularly suited to conveyor drives and materials handling applications across a range of industries, including manufacturing, mineral processing, primary processing, resources, energy and water and wastewater.

Bonfiglioli's HD drive series is a new generation of large industrial drives engineered to produce good reliability and torque densities to record values. The drives feature excellent torque distribution across their entire ratio range, with gear ratios laid out in close progression, along with having a rugged capacity to cope with the shock and impact of intermittent loads.

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.
