03 The Smart Motor was

03 The Smart Motor was designed specifically for the needs of horizontal materials handling systems change of rotating direction are just two of the functions that are very easy to implement. Because starting and braking ramps can be set individually, there are no sudden uncontrolled torque changes that place stress on the mechanical components or unbalance the items on the conveyor. operating point during continuous operation and therefore rotate with lower losses — an effect supported by the additional energysaving function developed by Lenze. When designing the motor, Lenze made sure that the size advantages of smaller motors were not diminished by overdimensioned terminal boxes. As a result, it is also easy to convert existing materials-handling equipment because there are no structural hindrances to be expected. A motor with many possibilities As outlined at the beginning, manufacturers of materials-handling systems use drives that have been optimally designed for the task in question; also, they should not lose sight of the need for standardisation. In practice, however, there is a huge number of preconfigured geared motors that basically only differ from each other in respect of their different speeds of rotation. This variance results in more engineering work, more documentation and larger stocks, to mention only three areas within the valueadded chain that can be improved. Lenze has calculated that, with the Lenze Smart Motor, variance can be reduced by 60 to 80 per cent. The chief reason for this is that speed of rotation of the Lenze Smart Motor can very easily be set on site. With one single variant, motor speeds of 500 to 2,600 revolutions per minute with constant torque can be covered. Another highlight is the process of speed setting itself, which can be carried out without touching (i.e. remotely), without addressing and without the application of voltage. For the parameterisation, Lenze uses NFC technology – Near Field Communication – which is in-creasingly becoming a standard feature of smartphones. When used in conjunction with a smartphone app from Lenze, it is a very easy way to prepare motors for the tasks they have to perform, without any voltage being applied. A pleasing side-effect of the smartphone app is that the technical requirement for telephone programs to be kept very small means that the commissioning tool must be made as simple as possible. Immediately after the item of equipment has been unpacked on the workbench, this app can be used to set the desired speeds and ramps. This can also be done directly after installation of the equipment. The whole thing is easy to use and works like a remote control unit, in particular without it being necessary to screw it on first. In addition, the motors have two digital inputs and one output. They make it possible for a control unit to give the motors two different speeds (creeping speed and operating speed) as well as start and stop commands. Moreover, soft starting and a No more contactors Things are also made easier when it comes to wear and tear. The Lenze Smart Motors inte-grate the function of contactors electronically. This creates space in the control cabinet and simultaneously avoids the wear associated with mechanical switching contacts. Full motor protection is also integrated. This means that the motor temperature, for example, no longer has to be monitored externally. Easy ordering process with just a few types of motor, no risk of motors being mixed up during installation, plus easy commissioning. The Lenze Smart Motor is a solution with which a large number of horizontal materials handling tasks can be performed, without the need for costly and time-consuming variant management. This results in enormous efficiency gains along the entire value-added chain — a quantum leap forward, making everything a lot easier.

Product News Couplings with a small diameter Delta v-belts for high-turnover mass products The Gates Delta v-belt is a profitable solution for all default industrial drives. Production takes place entirely in the European factories of the manufacturer under compliance with all company quality standards. The range comprises of two product lines: the coated Delta Classic V-belts and the also-coated Delta Narrow V-belts. Both product lines are available in all common sizes, cross-sections and lengths. Both profiles use the same high-quality rubber mixture and highly tensile-resistant polyester cords. They are antistatic and meet the requirements according to REACH and RoHS 2. They are designed for use at temperatures from -30 to +70 °C and convince by flexibility, stability and smooth operation. All models are available ex stock. Compact multi-axis systems for automation The company Reich-Kupplungen, based in Bochum (Germany), has developed a new range of cardan shaft couplings, which are particularly short and have a very small diameter. The compact cardan shaft coupling (KGV) is adapted by default for cardan shaft connections in compliance with the DIN standard. Reich-Kupplungen also offers the couplings with other connections for customised solutions. KGVs dampen torsional vibrations and peak loads, thus protecting the shafting and the machine. Furthermore, they are fail-safe, electrically insulating, capable of withstanding high overloads and suitable for use at temperatures up to 120 °C. The diameter is barely larger than the cardan shaft. Up to size 150, the couplings can carry nominal torques of 1,800 Nm and absorb peak loads of up to 4,000 Nm. In automation, an average of five axes per application or machine is normal. With its new compact multi-axis automation system LTi (Germany) offers scaleable servo drive system, a fully integrated IPC-based controller and a safety solution for multi-axis motion. SystemOne offers the optimum automation solution, featuring axis controllers in single, double and triple axis variants in a power range up to 32 A. A central feed, a DC power network and 24 V via a front-mounted rail system all ensure easy installation with minimal cabling. The axis controllers include a scaleable safety option: From STO as per PLe, cat 4 and SIL3 or single axis monitoring through to multi-axis motion control – anything is possible. The integration of the safety control into the motion control not only saves on cost based on shared use of function modules such as memory and interfaces, it also offers the benefit of being able to share data. Mini frequency inverter delivers high performance WEG Electric Motors added the CFW100 mini frequency inverter to its line of frequency inverters. This compact inverter is available in three sizes (A, B and C) for rated motor power from 0,18 to 0,75 kW and rated current from 1.6 to 4.2 A. With a height of 100 to 126 mm, a width of 55 mm and a depth of 129 mm, the CFW100 units are among the smallest frequency inverters currently available offering many applications at the user’s fingertips. The mini frequency inverters with integrated micro-PLC are particularly suited to simple technical applications. With its combination of extensive functionality and extremely small size, the CFW100 is easy to integrate into electrical cabinets and machines. This gives users an especially compact and cost-effective solution for controlling the speed of three-phase induction motors. MDA Technologies 2/2014 39
