Hannover Fair 2013 exclusive show report

23 June, 2013

SEW-Eurodrive has also extended some of its motors ranges, including the CMP series of servomotors, which has a new model that extends peak torque levels to 320Nm. The compact CMP112 motor can be mounted on modular gearboxes and has a low-inertia rotor that allows it to achieve high angular acceleration rates and short cycle times.

SEW’s DR modular motor system has also been extended by the addition of higher-power sizes (250/280) offering a choice of IE1, IE2 or IE3 efficiencies. The motors, which have shorter bodies than previous models, are available by themselves or as gearmotors.

Another company expanding its motor ranges is Siemens. For example, it has launched a second generation of its Simotics HV H-Compact motors for LV and MV applications. The high-output, low-noise machines have power densities that are 5% higher and efficiencies that have been raised by 0.4% to 96.5%. They cover power ratings from 900–4,000kW and can be ordered as explosion-proof versions operating from 690V–11kV.

Siemens has also produced a range of explosion-proof LV motors based on its 1LE10 series. The new 1MB10 machines are available in IE1, IE2 and IE3 versions and in Ex t or Ex nA protection for use in Zones 21/22 and 2. They cover ratings from 0.75–18.5kW in shaft heights from 100-160.

An expansion of Siemens’ Simogear geared motors family (above) takes torque ratings up to 5kNm and power ratings up to 30kW. The motors are available in IE2 or IE3 versions with low-backlash versions available as an option. The gearboxes are now Atex-certified for use in zones 1, 2, 21 and 22.

WEG has extended its range of roller table motors for the steel industry so that the biggest size has been increased from IEC 200 to IEC 400. The low-maintenance machines, available with four to 12 poles, can deliver up to 2.972kNm of torque.


For the first time, Beckhoff is offering users the option of displaying status messages or diagnostic information on a module that integrates directly into its EtherCat I/O system. The DIN-rail-mounting EL6090 EtherCat display terminal (shown below) has a two-line illuminated LCD and a non-resettable hours counter. It reduces installation and parameterisation efforts. The lines scroll automatically if the 16-character limit is exceeded.

B&R Automation has increased the temperature ranges of its IP20-protected X20 and IP67-protected X67 I/O modules. The modules will now operate in temperatures from –25 to +60°°C and can be stored at temperatures from –40 to +85°C.

Eaton has developed an Android phone and tablet app for its easy800 control relays that allows users to monitor and operate the relays remotely over a distance of up to 10m using Bluetooth communications. The easyRemote app can be used to change function block parameters, display text, change operating modes, set dates and times, and to check circuit diagrams. It allows users to avoid noisy or dangerous environments.

Lenze has launched two ranges of PC-based controllers for simple motion and sequence control tasks (shown above). The c300 cabinet controller, which comes with built-in EtherCat and CanOpen interfaces, is claimed to be the most compact small controller in its class to offer motion control functions. It can be connected in series with I/O modules from Lenze’s I/O system 1000. The second arrival is the p300 panel controller targeting low-to-medium complexity control and visualisation tasks. It aimed, in particular at harsh environments, and offers a choice of touchscreen displays from 10.9–26.4cm. Extension modules to support Profibus and Profinet are planned.
