Rotalink Catalogue Aids Power-System Selection

A revised full-range catalogue from Rotalink includes products and technical information, allowing customers to select miniature power-transmission systems and controls. The catalogue includes volume-sourced, low-cost DC, AC and stepper motor technologies from global partners, which are integrated with in-house designed and manufactured miniature gearboxes, motor-feedback components and motion-control technologies. Rotalink offers solutions for miniature power-transmission systems up to 28Nm torque and to 150W shaft power.

With its own manufactured range of planetary and ovoid-style gearboxes that include a choice of standard or enhanced polymer gears with sintered or ball bearings, it is possible to exactly match a customer's specification. The choice of advanced materials and Rotalink's ovoid gearboxes with spur/planetary output stages can yield high torque in space-restricted envelopes and they are suitable for applications where miniaturisation in design or maximising power to size is important. By adapting these same gearbox designs with Rotalink's space-saving incremental or absolute-encoder feedback devices, and by adding speed or positional motion control, Rotalink provides a complete single-source service for miniature linear or rotary power-transmission systems.

The catalogue includes complete specification information for three recently introduced DC motor technologies - high power brushed DC motors with neodymium rare-earth magnets, heavy-case low-inertia brushed DC motors and low-cost brushless DC motors complete with hall-effect sensors for commutation. Also available in the catalogue is a brushless version of the Red Drive programmable motion controller for up to 10A output from a 12 to 24V DC source with up to 27 configurable analogue and digital I/O points for comprehensive machine-control interfacing. For each of the DC, AC and Stepper motor sections, a detailed selection guide is included with available technical-assistance information, such as countermeasures for EMI and a discussion on customisation options for DC motor gearbox applications.

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...

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...

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.
