Siemens’ Industry Sector’s Drive Technologies Division has announced it will be presenting at Hannover Messe 2013 from April 8 to 12 its improved Arpex couplings and its extended Simogear range of geared motors.

The division will also present its “Integrated Drive System” (IDS) at the event. It described IDS as a whole new dimension in solutions for drive tasks: IDS integrates the division’s uniquely complete product portfolio.

Meanwhile, the company said it has expanded its Simotics XP portfolio with new explosion-proof 1MB10 motors.

Compared to the previous version, the new Arpex all-steel high-performance couplings are characterised by an increased axial offset and a larger bore capacity in the coupling hubs.

They also have a lower weight, yet a higher torque capacity. This has been achieved by an optimised component geometry, for instance the improved centre of gravity of the half coupling. Arpex high-performance couplings are particularly suitable for high-speed applications in the power generation, oil and gas, chemical and petrochemical industries, and are especially used in gas and steam turbines, generators, compressors and pumps.

The couplings have been designed for use in potentially explosive atmospheres in accordance with 94/9/EC and meet the requirements of API 671 / ISO 10441. The Arpex high-performance couplings can withstand temperatures between -40 °C and +280 °C in operation. Depending on customer requirements, they can also be adapted to other temperature ranges.

The company presents the next expansion stage of its Simogear family

The new couplings will be presented at Hannover Messe 2013.

SIMOGEAR GEARED MOTORS
In the next stage of the Simogear range of geared motors, the torque range for helical, parallel shaft and bevel geared motors has been extended by rated gear unit torques up to 5 000 Nm and the performance range has been extended by power ratings up to 30 kW. The geared motors are now available in efficiency class IE2 and IE3.

For applications that demand a particularly high degree of precision when positioning, Siemens offers the gear units in a low-backlash version. Ductile iron housings can be supplied for harsh ambient conditions with high vibration and
shock loads.

With immediate effect the Simogear gear units are certified in accordance with Directive 94/9/EC (ATEX) for use in potentially explosive atmospheres, for zones 1, 2, 21 and 22.

The focus of the Simogear geared motor range is on general materials handling, in particular the automotive, logistics and food and beverage industries. The motors are also used in the chemical industry, in crane technology, in environmental and water technology as well as in metal production and in the mining industry.

SIMOTICS XP PORTFOLIO
The Siemens Drive Technologies Division has supplemented its Simotics XP portfolio with explosion-proof 1MB10 motors which are available in efficiency classes IE1, IE2 and IE3. The 1MB10 motors have been designed to enable pumps, fans and compressors and meet all requirements that provide maximum safety within an Ex environment.

These explosion-proof 1MB10 motors belong to the Simotics low-voltage motors from Siemens. They are available in dust explosion protection (Ex t) and in non-sparking design (Ex nA). The motors find their conventional usage in Zones 21/22 (dust) and Zone 2 (gas-vapor-mist) which has been classified in accordance with the directive 94/9/EC (ATEX 95) regarding equipment and protective systems intended for use in potentially explosive atmospheres.

The 1MB10 motors are the modified version of standard 1LE10 series. All the motors are available in efficiency class IE1 (standard efficiency), IE2 (high efficiency) and IE3 (premium efficiency) and henceforth contribute in the adequate reduction of energy costs and CO2 emissions during their operation.

The motors cover a performance range from 0.75 kW to 18.5 kW and are available in shaft height ranging from 100 to 160. The 1MB10 motors are identical in design with the 1LE10 standard motors.

In the chemical and petrochemical industry explosion hazards are ubiquitous. Such hazards are also present in the wood industry or for example in the agricultural sector as well. Ignition risks are highly probable due to gases, fumes, mist or dust present in high concentration that get easily mixed with oxygen in the air and release the so-called minimum ignition energy – required to ignite a combustible particle. Legislators in many countries have implemented appropriate stipulations in the form of regulations based on national and international standards to ensure maximum safety in these areas.

The division also announced it had supplemented its Simotics HV Series with the second generation of H-compact Plus motors for low and medium voltage applications. These motors feature high output and low noise levels and offer a wide selection of cooling configurations ranging from air-water-cooling IC8xW and air-air-cooling IC 61x to open cooling IC01 for 2-and 4-pole machines. Enhanced with sub-critical design the H-compact Plus motors allow the full speed control range to be used.

INTEGRATED DRIVE SYSTEM
The Siemens Drive Technologies Division will be presenting the Integrated Drive System (IDS) at Hannover Messe 2013, a whole new dimension in solutions for drive tasks: IDS integrates the Division’s uniquely complete product portfolio. IDS thus provides full and reliable integration of the drive train with different focuses for almost all industries. IDS covers all relevant drive technology performance classes and provides customers with a high level of productivity, efficiency, and reliability. Ralf-Michael Franke, CEO of Drive Technologies Division, stated: “With the Integrated Drive System, we are writing a new chapter in the success story of drive systems from Siemens. We are providing our customers with a comprehensive range of possibilities for optimum use of the most all-embracing product portfolio for electric drives, which we have been innovating continuously for more than 160 years.”

In technological terms, the IDS concept is based on three-fold integration: Horizontal integration already optimally attunes the components required for the drive train to each other and for their intended task in the factory. This is done by drawing on the vast Siemens portfolio of gear units, couplings, motors, and converters, which can be combined to optimise dimensioning for the task at hand. For example, the fully integrated Simogear range of geared motors, with its compact design that is suitable for nearly all applications. But IDS also pays in the highest performance classes. At Hannover Messe, Siemens will be showing a complex drive train for vertical mills in the cement industry. Use of ideal combinations of Sinamics converters, Flender couplings, and Simotics motors achieves a very high level of productivity, energy efficiency, and reliability during operation.

Vertical integration, that is, integration of the drive train into the system architectures of the industrial production processes, is an essential precondition for production with maximum value added: IDS therefore uses the integration of the drive train and its components into the TIA architecture of Siemens Industry: All TIA components, from the sensor level to the manufacturing execution system, are attuned to each other and enable maximum communication and control. As part of its IDS presentation, Siemens is showcasing integration of the Sinamics G120 family into the TIA Portal and announces integration of the Simotion controllers into the TIA Portal.

Life cycle integration is the third dimension of IDS. Siemens is offering comprehensive solutions throughout the factory automation or process automation life cycle. At every stage, from design to planning, engineering, commissioning, and operation, and to modern industry services, considerable optimisation potential can be leveraged. This includes not only integration of the drive train components into the TIA Portal, but also software products such as Sinasave for evaluating the most energy-efficient drive solution or the DT Configurator for fast selection of suitable products for a customised drive train.
