Marine Motors
VEM has significant experience in manufacturing marine motors, approved by major ship classification societies. These motors are tailored to meet specific client needs and are reliable under harsh marine conditions, used in applications such as ventilators, pumps, and hoisting gear.
Product Features
The motors are energy-efficient, universally applicable with IP 55 protection, and offer improved reliability. They come in various configurations and can be customized with components like brakes and speed monitors.
Technical Explanations
Marine motors must adhere to high technical standards due to their operational environment. They undergo audits and approvals by classification societies, ensuring compliance with design and production regulations. Motors are categorized for operation on deck or below deck, with specific protection types (IP 55 or IP 56) based on location.
Standards and Regulations
VEM motors comply with standards from various classification societies, including ABS, BV, CCS, DNV, GL, LRS, PRS, RINA, and RS. Motors are classified into essential and non-essential services, influencing spare parts requirements and approval processes.
Technical Data
Motors are available in various types and constructions, with standard operating voltages of 380 V, 50 Hz, and 440 V, 60 Hz. They meet overload requirements of up to 160% rated torque for 15 seconds, depending on the classification society.
Approval and Certification
VEM holds TYPE APPROVAL CERTIFICATES for various motor types from several classification societies. Certificates and detailed specifications are available online.
Design and Approval Requirements
Design and approval requirements vary by classification society, including ambient temperature, thermal class, and individual approval thresholds for essential drives. Motors are marked with certification details and ambient temperature specifications.
Specifications
The document specifies thermal class 155 [F] with a winding limit temperature of 105 K for motors ≥ 600 W and 100 K for motors above 600 W. The ambient temperature is set at 45°C, with possible variations upon agreement. Motors are designed for sea-water protection according to various classification societies.
Procedures
Essential drives over 50 kW require individual approval, and production surveys are necessary. Nameplate markings are provided in multiple languages, depending on the classification society.
Standards and Norms
The document references standards like DIN EN 60034-1 for tolerances and DIN EN 50347 for mechanical parameters, specifying tolerances for efficiency, power factor, slip, starting current, torque, and noise levels.
Recommendations
The document advises on necessary documentation for motor orders, including technical drawings and customer information, emphasizing adherence to classification society rules for coolant temperature and site altitude.
Technical Data
Motors range from 0.09 kW to 450 kW, with sizes from 56 to 355, made of grey cast iron, and have a rated torque from 0.60 Nm to 3,040 Nm. They are designed with a Δ/Y-circuit as standard and offer various types of construction according to EN 60034-7.
Key Data from Tables
Tables provide detailed motor selection data, including synchronous speed, efficiency, power factor, and other performance metrics for different motor types and configurations.
Overview
This document is a technical catalog for three-phase motors with squirrel-cage rotors, specifically designed for marine applications. It includes detailed specifications, dimensions, and spare parts information for various motor sizes ranging from 63 to 355.
Specifications
The motors are designed with surface ventilation and cooling method IC 411, offering a degree of protection IP 55. They are available in different types of construction, including IM B34, IM B14, IM B5, IM V1, IM B3, and IM B35. Flange dimensions are referenced for detailed measurements.
Dimensions
The document provides extensive tabular data on the dimensions of different motor models, including flange sizes, hole patterns, and other critical measurements necessary for installation and integration into marine systems.
Spare Parts
A comprehensive list of spare parts is provided, detailing items such as end shields, bearing covers, antifriction bearings, seals, fan components, terminal box parts, and more. The document outlines the availability of spare parts up to 5 years after the phase-out of a series, with technical support offered beyond this period.
Ordering Information
For ordering spare parts, specific data such as motor designation and motor number must be provided to ensure accurate fulfillment.

Technical explanations Application Motors in sea-water design have to be equipped at a high technical level, because they are subject to special environmental and operational conditions. The requirements for reliability are high and they are also subject to special regulations. Motors in sea-water design are used as drives for ancillary units on board of ships and they comply with the special climatic and mechanic loads of these application ranges. To ensure a high-quality engineering and technological design for new developments, reconstructions and repairs of ships the working procedures at...
