Germanischer Lloyd

UL Recognition

Russian Maritime Register

Bureau Veritas

Det Norske Veritas

Canadian Standard Association

ABS Europe Ltd.


Marine Classification Societies

• Ratings ensure that the ships are safe and able to provide insurance• VEM motors have the following type approvals:

– ABS / BV / DNV / GL / LRS / RINA / CCS / PRS / RS– Type approval + factory type certificate valid for a wide range of

applications– Classification of the customer's request or the classification

society regulations– Design of the rating agency

• Ambient Temperature• Temperature Class (F)• Temperature rise• Overload

– Classification shown on the nameplate


Classifications and certificates

• Standard DIN EN 10204:2005-01– Defines content of different

reports• Factory certificate 2.1

– Validates that motors comply with requirements

• Factory certificate Test report 2.2 – Not specified in the

standard• Type approval Test report 3.1

– Standard specifies measurements

– Independent party shall perform tests

• Test report 3.2– Standard specifies

measurements– Independent party/

authority shall perform tests


Classification societies DNV

• Ambient temperature 45 °C• Thermal class 155 (F)• Temperature rise 100 K• Shaft for motors to be classified

Area of use and application sets various demands:

• Deck machinery– Ventilation IEC 410 / fan

freeze up prevented– Equipment to withstand

ice, heat and humidity– Space Heater– IP 56

• Engine room– Often forced ventilated IEC

416– Space demand is critical– Vibration– IP 44– Water cooled

• Standard motors– No special requirements

Variable Options


Marine Design considerations

• Electricity supply– Voltage and frequency are

not as stable as in industrial grids

• Overload– eg. 1.5 x nominal torque

for 1.5 minutes

• Duration period– eg. S2-25 %, S3-30 min

• Properly sized motor to save: – energy – weight – Space– Other devices– Cost

Uncertainty of measurement of specifying losses IEC 60034-30IE1 ”medium”IE2, IE3 ”low”





Motors left out of the standard:

• VSD - Designed for frequency converter use• Submersible motors• Applications higher than 1000m above sea-level• Ambient temperature below -15 °C or over + 40 °C• Cooling liquid temp under + 5 °C or over + 25 °C• EX motors according to RL94/9/EG


Design Improvements

• Use of low-loss rotor and stator sheets• Better use of materials

– Longer rotor / stator– Use of thick wires and optimizing filling of slots– Shorter ends of windings

• Optimizing shape of slots• Larger surface area for cooling

– Smaller ventilation fan is needed• Reducing friction by using bearings without sealing


What do we need to know to offer?

- Motor or generator?- Environmental conditions- Voltage and frequency- Control range for Freq Control

drives - Torque curve- Duty cycles- Construction- Cooling- Classification society- Need for classification

- Certification type
