What is EC fan in Ahu?
EC stands for Electronically Commutated, and it combines AC and DC voltages bringing the best of both worlds. The motor runs on a DC voltage, but with a single phase 230VAC or three phase 400VAC supply. A high efficiency, low noise, and continuous motor speed control is possible with this.
What is EC fan?
EC fans are direct drive fans that are integrated into the cooling unit by replacing the centrifugal fans and motor assemblies. They are inherently more efficient than traditional centrifugal fans because of their unique design, which uses a brushless EC motor in a backward curved motorized impeller.
What is EC fan in HVAC?
An EC fan is essentially a digital fan. EC motors developed by Swiss Rotors use permanent magnets to create the rotor field, and a series of coils controlled by an electronic “commutator” to create the stator field. This electronic control is what gives EC motors their benefits.
How does an EC fan work?
EC fans are capable of intelligent speed control – further reducing energy consumption. EC electric motors utilise a permanent magnet in the secondary field. When the rotor is energised it creates a repelling magnet, thus allowing the motor to rotate within the field.
Are EC fans Variable speed?
An electronically commutated (EC) fan design delivers the combined benefits of AC and DC Fans. The electronically commutated fan’s DC motor has the advantage of a variable speed control built-in.
What is the difference between AC and EC fans?
To summarise, the difference between an AC fan and EC fan is: An AC fan has an alternating current and is very expensive to control without making it hum or buzz. An EC fan is basically a digital fan. It’s a lot easier to control.
Why EC motor is more efficient?
Put simply, EC motors are approximately 30 percent more efficient than AC motors because: Lamination and copper heat loss is reduced by 50 percent. Slip loss is reduced to 0. Inverter loss is reduced by 50 percent.
Can fan EC control?
The Can-Fan EC Fan controller regulates the speed of fans to maintain optimal temperature and humidity conditions within the grow room. The sensor monitors the current temperature and humidity levels within the growing room, and gradually increases the fan speed until levels are achieved.
Are EC motors variable speed?
Electronically commutated motors are getting a lot of notoriety recently. At times, these have been referred to as brushless direct current motors and EC motors. Variable frequency drives are interchangeably called variable speed drives and adjustable speed drives, which all mean the same thing.
