NEMAThe National Electrical Manufacturers Association (NEMA) sets standards for a wide range of electric products, including motors. NEMA is primarily associated with motors used in North America. The standards represent general industry practices and are supported by the manufacturers of electric equipment. The standards can be found in NEMA Standard Publication No. MG1. Some large motors may not fall under NEMA standards.

IECThe International Electrotechnical Commission (IEC) sets standards for motors used in many countries around the world. The IEC 60034 standard contains recommended electrical practices that have been developed by the participating IEC countries.

MOTORS

Motors are used in many applications all over the

world. The purpose of the electric motor is to

create rotation, that is to convert electric energy into mechanical energy. Pumps are operated by means of

mechanical energy, which is provided by electric motors.

8 TechTalk

Flameproof motors - protection type EExd (de)First of all, flameproof EExd (type de) motors are category 2G equipment for use in zone 1. The stator housing and the flanges enclose the flameproof motor parts that can ignite a potentially explosive atmosphere. Because of the enclosure, the motor can withstand the pressure that goes along with the explosion of an explosive mixture inside the motor. Propagation of the explosion to the atmosphere that surrounds the enclosure is hereby avoided because the explosion is cooled down by means of flame paths. The size of the flame paths is defined in the EN 50018 standard. The surface temperature of the flameproof enclosure should always be in accordance with the temperature classes

Increased safety motors - protection type EEx (e)Increased safety motors (type e) are category 2G equipment for use in zone 1. These motors are not flameproof and not built to withstand an internal explosion. The construction of such a motor is based on increased security against possible excessive temperatures and occurrence of sparks and arcs during normal operation and when a predictable error occurs. The temperature classification for increased safety motors is valid for both internal and external surfaces, and therefore, it is important to observe the stator winding temperature.

Non-sparking motors - protection type Ex (nA)Non-sparking motors (type nA) are category 3G equipment for use in zone 2. These motors cannot by any means ignite a potential explosive atmosphere under normal operation, see figure 1.4.6.

Dust Ignition Proof (DIP)Two types of Dust Ignition Proof motors exist: 2D/category 2 equipment and 3D/category 3 equipment.

2D/category 2 equipmentIn order to avoid static electricity to cause ignition, the cooling fan on a category 2 DIP motor for use in zone 21 (area with potential danger of explosion) is made of metal. Likewise, to minimise the risk of ignition, the external ground terminal is subject to more severe demands of construction. The external surface temperature of the enclosure, which is indicated on the motor nameplate and corresponds to the running performance during the worst conditions allowed for the motor. Motors for use in zone 21 (areas with potential danger of explosion) have to be IP65 protected, that is completely protected against dust.

3D/category 3 equipmentThe temperature indicated on a category 3 DIP motor for use in zone 22 (areas with minor danger of explosion) corresponds to the running performance under the worst conditions allowed for that specific motor. A motor for use in zone 22 has to be IP55 protected, that is protected against dust. The IP protection is the only difference between 2D/category 2 equipment and 3D/category 3 equipment.

Directives and methods of protection – Ex-motorsATEX (ATmosphère EXplosible) refers to two EU directives about danger of explosion within different areas. The ATEX directive concerns electrical, mechanical, hydraulic and pneumatic equipment. As to the mechanical equipment, the safety requirements in the ATEX directive ensure that pump components, such as shaft seals and bearings do not heat up and ignite gas and dust. The first ATEX directive (94/9/EC) deals with requirements put on equipment for use in areas with danger of explosion. The manufacturer has to fulfil the requirements and mark his products with categories. The second ATEX directive (99/92/EC) deals with the minimum safety and health requirements that the user has to fulfil, when working in areas with danger of explosion. Different techniques are used to prevent electric equipment from becoming a source of ignition. In the case of electric motors, protection types d (flameproof), e(increased safety) and nA

(non-sparking) are applied in connection with gas, and DIP (dust ignition proof) is applied in connection with dust.

Fig 1.4.4: The explosion occurs inside

the motor and is lead out of the motor through the flame paths. The temperature classification for flameproof EExd motors is

valid for external surfaces.

Fig 1.4.5: For increased safety motors EExe, no sparks may occur.

The temperature classification covers both internal and

external surfaces.

Fig 1.4.6: With non-sparking motors ExnA,

no ignition is likely to occur.

Figure 1.4.8: Different mounting methods

Figure 1.4.9: The enclosure class is stated by means of two digits IP followed by two letters; for example P55

Mounting (International Mounting - IM)Three different ways of mounting the motor exist: Foot-mounted motor, flange-mounted motor with free-hole flange (FF) and flange-mounted motor with tapped-hole flange (FT). Figure 1.4.8 shows the different ways of mounting a motor and the standards that apply for the mountings. The mounting of motors is stated according to the following standards:• IEC 60034-7, Code I, i.e. designation IM followed by the previously used DIN 42590 code• IEC 60034-7, Code II

Enclosure class (Ingress Protection - IP)The enclosure class states the degrees of protection of the motor against ingress of solid objects and water. The enclosure class is stated by means of two letters IP followed by two digits, for example IP55. The first digit stands for protection against contact and ingress of solid objects and the second digit stands for protection against ingress of water, see figure 1.4.9.

Drain holes enable the escape of water which has entered the stator housing for instance through condensation. When the motor is installed in a damp environment, the bottom drain hole should be opened. Opening the drain hole changes the motor’s enclosure class from IP55 to IP44.

The SituationThe old building was scheduled to be demolished before being replaced by a modern, multi-functional athletic centre. The university needed a unique, technically advanced solution for the new cooling system, as the building would be quite extensive. The centre was designed to serve different purposes, including training and sports activities as well as athletic competitions.

The University cited energy savings and low system noise as important criteria for the pumps in the air-conditioning system. Conventional low-efficiency pumps in a traditional solution were unable to meet their demands.

The Grundfos SolutionThe Grundfos air-conditioning solution that was installed met the university’s demands for innovation and sustainability. The cost of building the system was also reduced. The high-performance system serves the entire building. It uses what is known as “tertiary pump theory” for zoned air-conditioning. This means that each zone is independently controlled according to the required performance and desired zone temperature. This is perfect for the different activities that take place in the centre.

The pump solution makes use of Grundfos’ own TPE Global Communication Integration technique. Basically, it controls the flow of chilled water for individual air-conditioning units according to the specific area the unit cools. Grundfos developed this technology in order to achieve a better control over unit performance. This puts Grundfos ahead of other pump manufacturers through innovation.

This solution also eliminates the need for 2-way valves in the system, reducing costs and assembly space. Grundfos’ innovation thus proves its worth as responsible (lower costs) and forward thinking (simplifying system construction).

The OutcomeRivalling the best in Asia, the Athletic Centre of the Chinese Culture University was officially opened on 29 September 2005. The pumps have operated without difficulties since then. Accordingly, Grundfos has met the school’s demand for an energy saving, low noise, and environment-friendly air conditioner with long life.

The Grundfos solution is a creative way to ensure a comfortable climate inside the centre, so athletes can exercise in a comfortable environment

Established in 1961, the Chinese Culture University was formerly

referred to as the College of Chinese Culture. In 1980, the college

was upgraded and renamed the Chinese Culture University.

Located near the university by the mountain, the Ta-Hsiao

Building was the place where countless university students have

received their athletic training the last sixteen years.
