Altra Industrial Motion for variable speed motors

International standard IEC TS 60034-30-2:2016 for variable speed motors New international standards for electric motors In the industrial sector, electric motors account for about 70% of electricity consumption and are thus the most significant consumers of electrical energy. Reducing the energy requirements of these drive systems by increasing their efficiency contributes to an equivalent reduction in CO2 emissions. In the European Community, EU Directive 2005/32/EC and the follow-on directive 2009/125/EC established the first requirements for environmentally responsible design of energy-using...

Status of motor standards In the first place, the motor standards should be regarded independently of statutory provisions, which often use the definitions of applicable national and international standards but do not necessarily coincide with them. Our customers often expect, and sometimes even specify, compliance with European standards (EN) or international standards (IEC). There are presently the following important new standards which are applicable: Ecodesign standard EN 50598-2 and the follow-up standard IEC 61800-9-2 This standard specifies the procedure for determining the losses of...

International standard IEC TS 60034-30-2:2016 for variable speed motors New standard IEC TS 60034-30-2 for variable speed motors The new standard IEC TS 60034-30-2 was released on the 8th December 2016 and will remain unchanged until 2019. It applies to all motors in the power range from 0.12 kW to 1,000 kW which cannot be operated directly from the AC line. Only servo motors for dynamic motor control applications are excluded. The efficiency is specified for a load point at 90% rated speed and 100% rated torque. The additional losses due to the inverter (harmonics) are also taken into account...

Scope and design points of IEC TS 60034-30-2 For efficiency classification, the rated point of the motor is equivalent to the rated point of the frequency inverter according IEC 61800-9-2 and is located at the junction of 90% rated speed (n90) and 100% rated torque (MN ). Testing at 90% speed allows for the voltage drop of the electronic components of the frequency inverter, so that the motor operates with constant magnetic flux.
