EC Technology and EC Fans
Axair Fans has set up long haul associations with manufacturers ECOFIT s.a. (France) and ROSENBERG Gmbh (Germany), and are presently ready to offer Energy Efficient EC fans and air development items. Both Ecofit and Rosenberg create and produce their own engines and fans. The Ecofit EC range use engines from 65 up to 113Wa, the Rosenberg range use engines from 1.1 up to 3.4Kwa engines.
What is EC innovation?
EC Technology represents Electronically Commutated and joins AC and DC voltages, which is basically a fan with a brushless DC engine, bringing the best of the two advances. The engine runs on a DC voltage, however with an ordinary AC supply. DC engines as of now have low power utilization however whenever utilized in an AC application.
The power required changing AC over to DC, utilizing a cumbersome, wasteful transformer. The EC engine fuses voltage change inside the engine. The non-pivoting part of the engine (stator) is reache out to account for an electronic PCB board which incorporates power change AC to DC, just as the controls.
EC Motor – Principle
With an EC engine the electronic hardware remains in lieu of the conventional mechanical recompense meaning the perfect sum is being provided the correct way at undoubtedly the perfect time giving exact engine control.
Long-lasting magnet brushless DC engine inside the rotor
The stator is drive by electronic switches (which supplant the Carbon brushes), constraine by a microcontroller.
Electronic framework (corridor impact sensor or programming is utilized to perceive the rotor position)
AC worked (230Volts Single stage or 380/480Volts 3phase, 50/60Hz)
Benefits
Energy reserve funds : Minimum power utilization and preferred productivity over AC same.
Control : 100% speed controllable, not recurrence dependant. Can be set-up for consistent wind current or steady strain applications, 0-10VDC or PWM control signal.
Low engine temperature : for longer lifetime than AC same
Straightforwardness : Electronic and power change are totally incorporate inside the engine.
Superior execution : Speed can be driven up to 3600rpm, one EC fan supplant numerous sort of engines (2, 4 and 6 post)
Simple association : No muddled wiring and set-up with a Frequency Controller, EC fans have almost no design.

Productivity
EC innovation engines have a close to level productivity bend which scarcely fluctuates across the speed range.However a scope of which isn’t restricte by coordinate velocities or powerless to voltage varieties like its AC partner. Its AC comparable will work at an exact point on the bend which likens to its most extreme effectiveness, either side of this point and the productivity lessens.
Ordinary AC engines have misfortunes as far as influence utilization (copper + iron misfortunes), slippage and frictional misfortunes (mechanical influence). EC engine have no slippage misfortunes, lessening misfortunes and expanding effectiveness.

By looking at 2 in reverse bended outward impellers, one in AC and the other in EC.
The Rosenberg EC Motor
The Rosenberg EC engine (EC = electronically commutated) is an inverter-took care of simultaneous engine with super durable magnets in an outer rotor plan. The AC mains voltage is redressed by the substitution hardware of the EC engine. A downstream inverter gives the engine the engine voltage relying upon the heap, like the standard of a recurrence inverter. Related , all boundaries of the substitution hardware and are ideally matched to one another.
The smart EC substitution hardware conclude how the engine windings in the stator are provided with current (compensation) contingent upon the place of the engine, bearing of pivot and speed set point. Long-lasting magnets create the attractive counterfield in the rotor, the force need for pivot is produce from the connection of the stator and rotor fields.
A mounting rib on the rotor is utilize for stable impeller mounting. The basic and speedy electrical association is make either through a terminal box with link organs or an association link, contingent upon the engine series.And the utilization of profound furrow metal rollers shut on the two sides with exceptionally paired oil guarantees upkeep free and low-commotion activity. The winding protection meets warm class F. Using shrew gadgets, a wide assortment of control and controlling capacities can be take by the EC engine relying upon. The space of use (boundlessly factor speed control, pressure control, volume stream control, temperature control, air quality control).
Benefits:
- High Efficiency
- Low power utilization
- Incorporated observing capacity (engine temperature, locked rotor and some more)
- Straightforward association (Plug and Play)
- Extended usefulness (pressure control a.s.o.)
- Minimized plan

The EC fan can pivot at a higher speed (2950rpm) than the AC (2750rpm) with a more modest engine than the AC fan (2.41 rather than 1.52Kwa). However the information for the AC fan is the devoured fan power and bars misfortunes from any inverter or regulator important to control the fan.

We should accept a laminar stream workstation requiring 13200m³/h at 450Pa. This requires 4 off Ø315 in reverse bended fans. Presently let us expect that this workstation works for quite a long time of the year and for 8 hours of the day at maximum speed. During non working hours to keep up with the workspace, the fans are run at generally a large portion of the wind current.
