Centrifugal fan RVE45 by ebm-papst
The main pride of the RVE45 fan is its extremely dynamic EC motor offering fast and at the same time reliable switching between high-pressure mode and significantly reduced-pressure mode. The high speed - up to 38,000 rpm - provides the required performance.
Maintenance-free ball bearing, vibration-damping materials and excellent aerodynamics ensure quiet operation for many years.
The product is manufactured in 2 models:
- RVE45-3/54/2P – 24 Vdc supply, 513 l/min air flow
- RVE45-3/52/2P – 12 Vdc supply, 450 l/min air flow
Motor, connection, and construction
Unlike the RV45 series, the RVE45 series already has integrated control electronics. Speed is controlled by a PWM signal or analog voltage. There is also an output signal to inform you of the actual speed.
Motor
- very compact thanks to the new design
- special strong magnets used
- lightweight rotor for highly dynamic operation - it can accelerate up to 80 revolutions per millisecond
- blade geometry is optimized for aerodynamics, the rotor can withstand high pressures and up to 38,000 rpm
- it is quiet at a given performance - 58 dB (A)
- minimal vibrations - dynamic balancing of the impeller-motor unit
- very simple - 4 wires with free-end
Construction
- case optimized for noise reduction
- easy to fasten in the application with screws
5 key areas of suitable use of the RVE45 fan
“Due to its properties, this centrifugal fan is especially suitable for the applications where a dynamic air supply at high static pressure is required. The extremely compact fan, about the size of a tennis ball, is therefore suitable for applications such as fuel cells, smoke detection systems or packaging machines,” continues Pavol Buhla.
The 5 main areas that are mentioned below represent in what kind of applications you can already find the RVE45 fan:
- vacuum lifters
- breathing masks (eg in a paint shop), which can also be powered by a battery
- hospital beds with anti-decubitus mattress
- dust extractor in nail studio
- production of bubble wrap
"It is already clear at first glance that dynamics is needed in many of these applications.
However, the RVE45 centrifugal fan can change speeds from 0 to 38,000 rpm in less than 500 ms. And active braking means that the fan can achieve similar dynamics also when reducing speed,” concludes Pavol Buhla in a review of the new product from ebm-papst.
