Approvals and certifications

China Classification Society

Lloyd´s Register of Shipping

Polski Rejestr Statkow

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

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 0

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
