General information

Energy management ISO50001

Below you find a brief summary of the purpose of energy management and the current status of the guidelines. The international standard ISO 50001:2011 was published in June 2011. The standard specified the requirements for putting a power management system. The standard describes how those requirements for a company to fix, implement and improve an energy management system. The standard aims continually to achieve improvements of the energy companies and their energy efficiency and to optimize the use of energy and to reduce costs.

EU directives for electric motors

General. Less energy consumption, less CO^2.  The European Union has drawn up a comprehensive legislative energy consumption in order to reduce CO² emissions.

Electric actuators are responsible for about 65% of industrial energy consumption in Europe. According to study by the European Commission, 63 million tons of CO² a year and an annual 135 billion kWh of energy savings are submitted by improved energy efficiency of the European user. The aim is to achieve a reduction of 20 to 30% by 2020. With a fine result to decrease CO² emissions.

To achieve this goal, the producers of low-voltage motors are forced to innovation and energy efficiency. This is how the four energy efficiency classes IE1, IE2, IE3 and IE4 from low to high efficiency exists.

Definition

Description of a motor means a three phase 50/60 Hz induction motor features:

• 2 to 6 poles
• Voltage rated VN to 1KV
• A power rated PN  between 0.75 KW and 375Kw
• classified as class S1
• Servo motors based upon their work cycle are excluded

RETURN FORMAT RELATED ENGINES

New output format for asynchronous motors is logged in the IEC 600034-30.

IP stands for international Efficiency

• IE1 = Standaard Rendement
• IE2 = High Efficiency
• IE3 = Premium Efficiency
• IE4 = Super Premium Efficiency
• IE4 defined in standard, values logged defined in  IEC/TS 60034-31

 Time frame entering new requirements

• Phase 1:  from 16/06/2011 electric motors in use, must suffice minimum efficiency level IE2.
• Phase 2:  from 01/01/2015  all engines should be offered when presented with a frequency inverter to the IE3 level or IE2 level by engines ability of 7.5 kW to 375 kW.
• Phase 3:  from 01/01/2017 also the smaller engines are added to the program. All 2, 4 and 6 pole motors from 0, 75kW to 375kW must from this date meet the IE3 standard, or the IE2 engine must be used in combination with a frequency inverter.

EXCEPTION BY THE RULES

In the second phase standard exceptions of energy policy apply. Following engines are exempt to the new efficiency standard IE3 and need, therefore in case of a lower yield indication not to be increased.

• Motors designed for immersion in liquid.
• The engines, which are fully integrated into a product, such as a pump, fan or compressor and gears, whose energy-efficiency of the product is not independently, can be determined.
• Special engines;                                                                                                                                                                                                                                                                      at an altitude of 4000 m above sea level;                                                                                                                                                                                                                                                                                                                                                    at an ambient temperature of about 60 ° C;                                                                                                                                                                                                                                                                                                                                              at an ambient temperature of less than -30 ° C or below 0 ° with water cooling;                                                                                                                                                                                                                                                                                Motors equipped with coolant and cooling become active at temperature below 0° C or  above 32°C;                                                                                                                                                                          
• Engines for extreme operating temperatures of more than 400 °C ;                                                                                                                                                                                                                                                                                          where explosion hazard applies, as described in Commission Directive 94/9/EC.
• Brake Motors
• explosion-protected Motors (Ex d/Ex, Ex e, Ex n and t) and belonging to the series, 1PS4, 1MD5, 1PS1, 1PS2 1 PS5, 1 MJ, 1 MA, 1MB1 or an explosion proof execution the 1LA/1LG with custom options.
• Motors specially with a frequency inverter according to IEC600034-25 performed
• Motors specially for intermittent operation (S2 to S9) designed, with user-defined options.
• motors with eight or more poles. Engines with paged (direction of rotation) poles; Synchronous motors; single-phase motors.
• changes from the previous guidelines drawn up.                                                                                                                                                                                                                                                                                                                                  The former voluntary EU CEMEP (Association of European manufacturers) agreement is replaced by the EuP directives. These EuP directive must be converted to national legislation in all European countries.
• 6-pole motors as now the 2-and 4-pole motors must meet the guidelines
• The included nominal power is expanded from 1.1 – 90 Kw to 0.75 – 375 kW
• The nominal voltage rises 400 V to 1000 (not incl.)
• Geared motors are now also EuP standard.

The Efficiency classes as defined in IEC 60034-30 are determined on the basis of loss corresponding to the standard (IEC 60034-2-1). The lost returns are not added with a fixed percentage, the actual lost must be measured.

INVESTMENT AND SAVING AT THE SAME TIME.

Below a realistic cost statement of a 7, 5kW electric motor. You can see that cost of procurement and service is only a small part of the total energy consumption costs.

IN ANTICIPATION TO START

1. The 0-line of the company. What is the energy consumption of the total company and/or the machine setup. Measurements, monitoring and analysis will be needed or to be offered.
2. Knowledge of the largest consumers and how to affect it.
3. instruction and training of staff.
   
   

Immediate possibilities, energy management as a success factor

Example: motor of a graphic printing machine.

Know you  largest consumers, to generate the largest energy saving

Ø  Conversion of main engines to EuP (“Energy using Product”) standard and meet simultaneously ISO150001. Expected energy saving between 5% to 20%. It depends on the used motor AC or DC. A 5Pk DC main engine conversion to AC can result in a profit of 0, 55Kwh. Electricity costs reduction directly at exchanging a DC motor to AC motors. DC motor power requirements with a higher consumption recording pro phase with average 33% higher than AC motors which in contrast to the advantage of the AC motor power consumption – directly online by phase is equal.

Ø  When using vacuum systems. Use of intelligent vacuum pump switches – Ives-. This implementation is only possible if the company has a central vacuum. When having Ives, installed, you will have best of both worlds with minimum of investment, an energy saving between 0,75Kw and 2, 25Kwh (equivalent to a saving of 0, 75Kwh per pump) can be achieved.

Ø  Machine lighting. Exchange conventional lighting to LED lighting becomes based on conventional 4 x 60W consumption =>0, 24Kwh. In contrast to LED,  consumption reduces to => 0, 04Kwh. Power saving of =>0,20Kwh.

To realize the measurements on a machine as displayed with 11KWh in the current state, a total consumption of energy saving will be generated up to 27%.

• Security of man and installation
• Increase preventive action
• Inspection obligations*
• increase efficiency
• Liability Insurance obligation*

Inspections are executed by  Graphic Supports with qualified people.

INSPECTION DUTY

An inspection duty can be imposed by nationals and international laws. Also insurance conditions can result in installation and machine inspection duties and obligations. Depending on legislation relating to the business,  installation, machinery and equipment and whether they are movable or not. There is increased risks of annual inspection duty. Be informed.

Duty Obligations supports ISO50001 by means of clear monitoring support, measurement and analysis reports.

Be prepared. Think of

• Inspection interval Required
• Inspection intervals of your installation for electrical appliances and machines
• Pay attention, when buying machine or product, please note CE certification
• Make sure diagrams (electrical drawings) are available and complete
• During executing completion of installation make sure an inspection and report is executed
