What does EC mean in fans?

electronically commutated
An electronically commutated (EC) fan design delivers the combined benefits of AC and DC Fans. The EC fan’s power comes from a brushless DC motor, but it offers the control that AC induction fans have over the fan rotor through a printed circuit board.

What is EC DC?

An electronically commutated (EC) motor is designed to run on an alternating current (AC) power supply, but it in fact bears a closer resemblance to a direct current (DC) motor. It is essentially a permanent magnet, brushless DC motor that incorporates on-board electronics.

Are EC motors AC or DC?

DC voltage
NOTE: An EC motor CANNOT be connected directly to AC line voltage. It uses DC voltage, and the external control converts to DC so that the motor can run. Put simply, EC motors are approximately 30 percent more efficient than AC motors because: Lamination and copper heat loss is reduced by 50 percent.

What is the difference between EC and AC 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.

What is an EC?

Electrical conductivity or “EC” is a measure of the “total salts” concentration in the nutrient solution (drip, slab or drain). It is expressed in milliSiemens per linear centimeter (mS/cm) or microSiemens per linear centimeter (mS/cm) where 1mS = 1000µS.

How is an EC fan controlled?

The speed control of an EC-motor is realized by its commutation control device by its own. In most cases this drive controller has a standard 230V mains connection, often as a wide range variation, i.e. 208V-277 at 50-60Hz. The user only needs to apply a suitable source for the speed-set-value.

What is EC axial fan?

SUNON EC Axial Fans feature an Electronic Commutation (EC) design, with a DC motor and an integrated AC to DC converter. This design allows SUNON EC Fans to have a smaller footprint, and lower power consumption, than standard AC powered Axial fans.

How do EC fan motors work?

The EC (electronically commutated) motor is a synchronous motor powered by an inverter with permanent magnets in an external rotor design. The stator is driven by electronic switches controlled by a microcontroller. The motor needs to be supplied with AC voltage and a DC voltage signal to operate.

Do EC fans need inverters?

The slightly higher investment costs for EC fans in comparison with conventional motors are mostly amortized within the shortest operation time because of the low energy consumption and lower installation costs (no transformer control, frequency inverter, or phased angle control is necessary).

What is the full name of EC?

The Full form of EC is Election Commission, or EC stands for Election Commission, or the full name of given abbreviation is Election Commission.
