Why EC Motor, EC Fan and EC Technology?

EC technology is intelligent technology; using integral electronic control which eliminates the slip losses in the motor and ensures that the motor always runs at optimal load and guarantees that the proportion of energy utilizable effectively is many times higher and the energy usage considerably lower compared with AC motors.

Constant volume or constant pressure functionality is easily achieved with the connection of one simple sensor or, in some cases, without any external sensors at all. Silent, infinitely adjustable speed control can be as simple as connecting a potentiometer to the motor. Commissioning becomes simplicity itself.

Average energy savings of 30%

In ventilation, air-conditioning and refrigeration technology, the world of information technology, heating or building systems. In industrial automation, automotive, or telecommunications. Wherever fan or drive technology is employed, it is necessary to continuously find ways to decrease energy consumption. Whatever their industry, our customers' goal is to be able to offer end products that simply save costs.

Energy is expensive and getting more so every day. The refrigerated case in the supermarket, the heating system in the single-family home, the climate control system in the office building: wherever energy is used, an average savings of 30 % is possible using EC technology.

Example 1: EC motors and fans-Energy savings in HVAC technology

At every speed, the EC fan by definition operates very efficiently. Thus energy savings of over 10 % is attained for condensers/ evaporators in which EC fans work, even at nominal speed. In the continuously controlled range, the relative and absolute savings are substantially greater.

Example 2: EC motors and fans-Energy savings in supermarket

The air-conditioning and refrigeration systems of a supermarket. This application requires peak loads on hot summer days; normal operation is adequate at moderate temperatures; and after sundown, whisper-quiet nighttime operation is required in order to not disturb neighbours. These are just examples, but are also real-world conditions that EC technology takes fully into account. With its intelligent open and closed-loop control options, the air-conditioning or cooling systems can be adapted easily to all requirements of manufacturers, owner/operators, consumers, and the general public. With guaranteed high savings potential for energy and thus for costs.

Minimal noise emission:

Think, for example, about air-conditioning in office buildings. Think about heating boilers in residential spaces, range hoods or refrigerators, electronics cooling of computers, ventilation and air-conditioning in the automobile, in commercial vehicles, and on and on. Of course, in all of these applications, function, reliability and safety are everything! Still, the consumer wants to hear absolutely nothing about it – quite literally. Here is something that sounds good: in every application, EC fans, EC blowers and EC drives made by GP provide power that can barely be heard!

Everything networked and controlled reliably:

There is hardly any application for fans in which maximum EC intelligence cannot demonstrate its advantages. Take, for example, the remote monitoring ability via Internet/modem, which makes all information, including speed, motor temperature and operating messages or alarms, available at any time – and, if desired, even anywhere in the world. Another example is the reduction of current reverse transfer and thus of harmonics, meaning less load on the power system – and, put simply, that wires, fuses and contactors can have lower ratings.

Easy Remote monitoring

Function monitoring via Internet/modem takes place via RS485 interface: LONWORKS, MODBUS RTU. The information can be processed and evaluated using software such as the GP LISA control software or software on the customer's side. The information is available worldwide via Internet. Preventive maintenance is possible this way. The following information can

be read out:

1) Running time

2) Speed

3) Current

4) Voltage (intermediate circuit)

5) Power input (can be calculated from current draw and voltage)

6) Temperature of motor

7) Temperature of electronics

8) Temperature of power section

9) Electronics temperature

10) Operation mode (control of temperature, pressure and air flow; actuator/controller; set value/actual value)

11) Operation and alarm display = alarm signal
