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

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
www.vem-group.com 24
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

New Classification for IEC 60034-30
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
www.vem-group.com 30
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
