The wide field of implementation includes the following applications:

  • Pumps
  • Fans
  • Compressors
  • Conveyor systems such as cranes, belts and lifting gear
  • High-bay warehouses
  • Packaging machines
  • Automation and drives

Обзор

Standard motors from Siemens are characterized by their flexibility, ruggedness and energy efficiency. In general, all motors are suitable for converter-fed operation with line voltages of up to 460 V +10 %. The motors are designed to fulfill the requirements of the European and international markets with an output range from 0.09 to 315 kW.

Standard motors for use worldwide

IEC motors for the European and international market

The standard motors comply both electrically and mechanically with the applicable IEC/EN standards. For exporting to China, CCC certified motors (China Compulsory Certification) can be supplied.

IEC motors specially for the North American market

Motors are also available to the NEMA specification (National Electrical Manufacturers Association), with UL approval (Underwriters Laboratories Inc.) and CSA certification (Canadian Standard Association) for exporting to NAFTA states (USA, Canada and Mexico). The mechanical design of all motors is compliant only to IEC/EN, not to NEMA dimensions.

High efficiency energy-saving motors for a positive energy balance

Depending on requirements, energy-saving motors for a positive energy balance are available that are compliant with the legal requirements applicable in the European economic area in accordance with EU Directive 640/2009 as well as for the North American market in accordance with US federal law EISA (Energy Independence Security Act).

Minimum efficiency according to EU Directive 640/2009

The EU Directive defines the minimum efficiency for 2, 4 and 6-pole motors in the output range from 0.75 to 375 kW. The efficiency levels are grouped into 3 efficiency classes (IE = International Efficiency):

  • IE1 (Standard Efficiency)
  • IE2 (High Efficiency)
  • IE3 (Premium Efficiency)

IE1, IE2 and IE3 efficiencies, 4-pole 50 Hz

At a glance: EU Directive No. 640/2009 based on IEC 60034-30
  • The EU Directive is in force in all countries of the European Union. Losses are determined and therefore the efficiency is determined in accordance with IEC 60034-2-1:2007
  • The following are specified: 2, 4, 6-pole 50/60 Hz squirrelcage motors from 0.75 to 375 kW, for all voltages < 1000 V

Efficiency requirements according to EISA

The Energy Policy Act (EPAct) was superseded in December 2010 by the Energy Independence Security Act (EISA).

Since then, EISA has extended the legal minimum efficiency requirements.

The following motors must satisfy the NEMA Premium Efficient Level (NEMA MG Table 12-12):

  • 1 to 200 hp
  • 2, 4, 6-pole
  • 230 V, 460 V

Exception/expansion – The following motors must comply with the NEMA Energy Efficient Level (NEMA MG Table 12-11):

  • 201 to 500 hp
  • 2-pole, 4-pole, 6-pole and 8-pole
  • All voltages < 600 V except 230 V and 460 V
  • Footless motors (IM B5 and other flange types)
  • NEMA design C (increased starting torque)

For details, see NEMA MG1, Table 12-11 and Table 12-12.

The EISA act lays down that the nominal efficiency at full load and a "CC" number (Compliance Certification) must be included on the rating plate. The "CC" number is issued by the US Department of Energy (DOE). The following information is stamped on the rating plate of EISA motors which must be marked by law:

  • Nominal efficiency
  • Design Letter
  • Code Letter
  • CONT
  • CC No. CC 032A (Siemens) and NEMA MG1-12
Energy-saving motors from Siemens in accordance with IEC 60034-30 or EISA

The product range of energy-saving motors exclusively comprises motors in the EU efficiency classes IE1 "Standard Efficiency", IE2 "High Efficiency", and IE3 "Premium Efficiency". The procedure for determining the efficiency is based on IEC 60034-2-1:2007. With these energy-saving motors, a significant reduction in energy costs can be achieved.

IEC motors from Siemens for the North American market are CC certified and stamped with the number CC032A on the rating plate. Motors are offered with the CSA Energy Efficiency Verification Mark specially for the Canadian market.

Example of a rating plate

IE3 double rating plate

For further examples, see Part 0.1 of Catalog D 81.1  2012.

Standard motors with increased output and compact construction

Standard motors with increased output and compact construction can be used to advantage in confined spaces. For a slightly longer overall length, the output is at least as high as that of the next largest shaft height. These compact motors are also optimized for efficiency and therefore reduce the operating costs.

Standard motors with reduced output without external fan

Naturally cooled motors with surface cooling without external fan are suitable for the following operating conditions:

  • Types of duty with adequate cooling times (e.g. temporary duty for positioning drives)
  • Environmental conditions that demand compact installation space (e.g. in motors with a stopping function)
  • Conditions which make an external fan disadvantageous (e.g. simple cleaning in the food industry, textile industry).
Preferred and Express motors

The most popular basic versions of motor series 1LA9 and 1LG6, and the corresponding successor types 1LE1001 and 1LE1501 are available under special terms as so-called "Preferred motors". Most of the "Preferred motors" are also available with a shorter delivery time as so-called "Express motors".

The standard delivery time for Express motors is 1 to 2 days from the time of clarification of the order at the factory until dispatch from the factory. To determine the delivery date at the customer site, the appropriate shipping time must be added.

For further information and the complete range, see "Preferred and Express motors".

General note

All the data listed in the catalog is applicable for a 50 Hz line supply. With converter-fed operation, the reduction factors for constant torque and drives for fans, pumps and compressors must be observed. Noise values for motors operating with a converter at frequencies other than 50 Hz are available on request.

Mechanical limit speeds

When the motor is operated at its rated frequency, it is important to note that the maximum speeds are limited by the limits for the roller bearings, critical rotor speed and rigidity of the rotating parts.

Ventilation/noise generation (converter-fed operation)

The fan noise can increase at speeds that are higher than the rated speed of self-ventilated motors. To increase motor utilization at low speeds it is recommended that forced-ventilated motors are used.

Mechanical stress and grease lifetime (converter-fed operation)

High speeds that exceed the rated speed and the resulting increased vibrations alter the mechanical running smoothness and the bearings are subjected to increased mechanical stress. This reduces the grease lifetime and the bearing lifetime. More detailed information on request.
