Compact DC Motor Offers 200W Power Output

Maxon Motor has unveiled a compact DC motor with a 200W power output. The RE 50 delivers high levels of nominal torque - up to 0.38Nm - from a drive measuring 50 x 108mm. This is achieved using a two-pole neodymium permanent magnet, combined with four different versions of the company's patented winding technology.

The heart of the RE 50, as with all mechanically communicated Maxon drives, is the ironless rotor, which is claimed to provide smooth running thanks to its minimal inertia. Low nominal voltage (24-70VDC), an operating efficiency of more than 90 per cent and good power density make the RE 50 suitable for advanced battery-powered applications such as electric tools, transport and logistics equipment, mobile systems and robotics.

Thanks to the Maxon modular system, the versatile new drive is compatible with the company's gearhead, encoder and control systems, creating compact, high-performance drives suitable for applications in automation, mechanical engineering or medical technology. The motor, combined with its integral graphite brushes, contains pre-loaded bearings that reduce vibration and offer quieter running for a longer service life. A heavy-duty version of the RE 50 is also scheduled for release. It has been designed for harsh environmental conditions, meeting protection class IP54 (dust and splash water protected), and will come with an additional brake.

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.
