ebm-papst at the SPS
Protection of the power electronics by compact fan
The drive technology and fan specialist ebm-papst has expanded its Axiforce compact fan series to include a fan at the bottom. The device is compact at 40 x 40 x 28 millimetres and, with a maximum static pressure build-up of 1,400 Pa, enables reliable operation in many high-performance electronics applications. It is infinitely variable in the speed range from 3,000 to 27,000 revolutions per minute using a PWM control input. An optionally available full encapsulation provides protection against salt spray and the ingress of water and foreign bodies. Continuous temperature changes and other weather conditions are no problem for this robust appliance.
New blade geometry
Another product highlight is the second generation of the Radical series, which aims to impress with its high volume flows, compact dimensions and pleasant noise behavior. Thanks to the possibilities offered by plastic production, a new blade geometry has been realized and the head gap has been significantly reduced. This results in fewer losses, higher efficiency and less noise. The flow grid has also been optimized and reduces noise even further compared to the current standard version in the event of installation-related suction-side interference. The new generation of Radical motors also impresses with its good EMC behavior. The fans are available with or without a ready-to-install housing in sizes 175, 190, 225, 250 and 280; size 206 is now new.
ECI series can be intelligently networked
The ECI series has established itself as an intelligent networking solution, for example the size 63 with integrated BUS interface under the term K5 electronics functionality. Now the internal rotor motors can also be addressed via EtherCAT using high-performance interface electronics. The advantages for decentralized drives lie in the synchronization of several axes, the reduced integration effort and a space-saving design in the machine. EtherCAT is real-time capable and offers high synchronization accuracy in the nanosecond range. The electronically commutated ECI motors of the modular drive system cover the power range from 30 to 750 watts in sizes 42, 63 and 80 millimetres, for example.
Crown wheel technology transmits "around the corner"
In many applications, it is necessary to transmit the power "around the corner". An efficient angular gearbox can be realized with crown gear technology. In areas such as decentralized drive technology, this highly efficient gear technology has now moved into focus. The right combination of motors, gearboxes and controls enables high energy savings even in the power range below 250 watts. ebm-papst has redefined traditional crown gear technology with the Etacrown series; the efficiency is in the region of 90 percent even with high reduction ratios, and over 90 percent in the single-stage range.
