Altra Industrial Motion Ecodesign Requirements according to EN 50598 Products for highest system efficiency

Ecodesign Requirements according to EN 50598 Climate targets of the European Union The numbers are familiar; around 70 percent of the energy demand of industry is due to electric motors. This corresponds to a CO2 emission of around 427 million tons. The European Commission is convinced that savings corresponding to the power consumption of Sweden can be achieved by appropriate measures. EU Directive ErP 2009/125/EC (Ecodesign requirements for energy-related products) defines the relevant preconditions. The EU member states agreed on 11 March 2009 at a meeting of the Ecodesign Regulatory Committee...

Ecodesign Requirements according to EN 50598 European Standard EN 50598 The new Standard EN 50598 consisting of 3 parts specifies Ecodesign requirements for drive systems, motor starters, power electronics and their driven devices. Part 1: General requirements for establishing standards for the energy efficiency of electrically operated equipment according to the expanded product approach (EPA) with semi-analytic models (SAM). This part specifies the procedure for determining the losses of the extended product approach and its components. A product committee is thereby able to couple the power...

Ecodesign Requirements according to EN 50598 CDM – Complete Drive Module The CDM - Complete Drive Module – contains the drive controller as well as auxiliary devices and input components. The efficiency classes IE0 to IE2 of the drive controller that are specified in EN 50598 refer to the 90;100 operating point, i.e. 90 % motor stator frequency and 100 % torque current. The reference drive controller has the efficiency class IE1. The following table shows the losses of a reference CDM (400 V, efficiency class IE1) according EN 50598. Reference values according to EN 50598-2 Pr,M *) This value...

Motors The efficiency classes for motors are subdivided according to IEC 60034-30-1 into the classes IE1 to IE4. The values refer to the operating point 100; 100, i.e. 100 % speed and 100 % torque. Motor manufacturers are not obliged to specify the loss values at all operating points. Bauer assists its customers and gives the loss values of its permanent magnet synchronous motors, so that they themselves can determine the overall losses and – as previously – proceed with their system optimisation and protect their core knowledge. Loss values of BAUER PMS Motors Pr,M *) This value is used in the...

Ecodesign Requirements according to EN 50598 PDS - Power Drive System A PDS or Power Drive System consists of a CDM – Complete Drive Module – and a motor. EN 50598-2 defines Reference Power Drive Systems that are based on a 4-pole reference motor of efficiency class IE2 and a Reference CDM with 400 V. The efficiency classes IES 0 to IES 2 refer to the operating point 100; 100, i.e. 100 % speed and 100 % torque. The reference values according to EN 0598-2 are given in the following table. Reference values according to EN 50598-2 PL,PDS [W] Relative Torque [ %] Reference system Relative losses...

How is the efficiency class of the PDS-System determined? The efficiency class of the system is determined by adding the losses of the CDM and motor at the operating point 100; 100, i.e. 100 % speed and 100 % torque. The IES class can then be read from the table. Relative Torque [ %] Relative Speed [ %] Loss values according to EN 50598-2 P Calculation example: 3 kW PMSM motor (IE 4) with an inverter (IE 1) Inverter losses: 299 W Motor losses : 427 W ------------------------------System losses 726 W ------------------------------- Reference system Relative losses

Where are the advantages for you? Bauer Motors provide efficiency advantages in partial load applications The specially developed Bauer permanent magnet synchronous motors of course meet the legal requirements of IE3 and IE4. Their strength lies however in their use in the partial load region. Owing to the use of Bauer permanent magnet synchronous motors, in standard applications under partial load conditions often more than 30 % energy savings can be achieved compared to the asynchronous motor technology. Reducing power supply output saves money End users and machine manufacturers benefit from...
