APPLICATIONS
ASI.CT.036.0 GB
This series of water cooled motors was designed by MarelliMotori for heavyduty applications where space and natural ventilation is limited. The integralwater jacket coolers provide an excellent power output for the compact motorsize as compared to traditional heat exchanger designs. These motors, originallydesigned for tight shipboard applications as main propulsion drives and auxiliarybow thrusters, now find themselves in heavy industry for compressors, pumps,rollers and other rotating equipment.
MarelliMotori has a tradition dating back to 1891 when Ercole Marelli foundedthe company. Today it forms an integral part of the worldwide FKI group ofcompanies. With over 100 years of manufacturing excellence and experience,MarelliMotori is recognised as a leading supplier to Industrial, Petrochemicaland Marine Industries offering a complete range of Low and Medium VoltageMotors and Generators. These quality products are backed up by an organi-sation of skilled people providing sales, service and technical support to thehigh standards demanded by customers.

GENERAL FEATURES
ASI.CT.036.0 GB
Robust construction designed for heavy, arduous and continuous duty in confined spaces.
Standards• IEC 60034• IEC 60072
Approvals• The motors are designed and built in accordance with naval specifications and approved by: ABS, BV, DNV and RINa
Mountings• Vertical or horizontal• Feet and/or flange mountings
Construction• Steel frame• Cast iron or steel terminal boxes and shields• IP55• Windings impregnated with VPI system (Vacuum Pressure Impregnation)• Insulation class F• Vibration grade R• Anti-corrosion and rust frame treatment• Stainless steel nameplate• Simple earthing• Drainage hole• PTCs in windings with terminals in auxiliary terminal box
Supply• Low or Medium Voltage• Inverter
Cooling• Fresh water coming from external circuit and circulating in the interspace lapping the stator core
Sound Pressure• Extremely quiet
Bearings• Ball bearings• Regreasing system• Arrangement for SPM sensor
Safety• Internal water leakage sensor
Advantages of Water Jacket Design• Heat removal from the installation area• Compact dimensions• Reduced vibrations• No dust circulation
Recommended Uses:• When limited space is available• When driven machine is already water cooled• When reduced vibration and low noise are required• When switchboard is already water cooled

Degree of ProtectionMotors are normally provided with IP55 enclosure. A higher degree of protection is available on request.
Environmental ConditionsElectrical tables refer to a cooling water of +38°C and altitude of 1000m a.s.l. Please contact MarelliMotori for different environmental conditions and wherecooling water temperature is less than 10°C.
InsulationAll motors have class F insulation which allows a maximum winding temperature rise of 107°C with cooling fluid temperature of 38°C. On request class Hinsulation compatible with winding temperature up to 127°C is also available. Please contact MarelliMotori for cooling fluid temperatures lower than +10°C.
Temperature RiseThe outputs shown in this catalogue refer to temperature rise F.
PROTECTIVE TREATMENTS
External SurfacesStandard finish is a heavy duty epoxy-vinyl paint. Colour is RAL5010.Special paint finishes can be provided to protect against: acids, alkalis, salt air, anhydrous gases and sea water.
Internal SurfacesSpecial tropicalised treatment of internal surfaces and electrical windings and inner cooling channels are coated with rust protector.
COOLINGIC 7 A1 W7 (Self-circulating primary coolant with integral heat exchanger using remote fresh water). Reduces the noise level and it is ideal for constant torque,low speed, inverter applications.
MATERIALS
Durability and reliability determine the choice of materials. Fabricated steel frames and cast iron shields are designed for reduced weight.Terminal boxes for frame sizes up to 400LB are in cast iron and from 400LC to 500 frame size in fabricated steel.Please contact MarelliMotori for different materials.Special steel shafts are available for high load applications.
BALANCING AND VIBRATION GRADE
The motors are dynamically balanced with a half key applied to the shaft extension in accordance with standard IEC 60034-14 to vibration grade reduced (R).On request vibration grade special (S) is also available.
Duty TypeThe tables shown in this catalogue refer to S1 duty type. The table below shows the correction factors to calculate the outputs for S2 duty.

DERATING FOR INVERTER SUPPLY
The B4J and B5J series have been designed to satisfy the requirements of speed control by frequency converter supply. MarelliMotori therefore provides varioussolutions to obtain the best performances.
To select the best solution please contact MarelliMotori supplying the following information:1. Load characteristics (quadratic torque, constant torque or torque curve for all other cases) of the driven equipment;2. Electric supply and speed range;3. Converter supply characteristics (peak voltage values at the motor terminals, rise time, etc.);4. Maximum inverter overload (time and current value).
Inverter fed motors will be supplied with enhanced winding insulation and N-end insulated bearing.
APPROVALS
In addition to meeting the electrical motor specifications, the B4J and B5J series also match the requirements of naval register rules for pressure vessels.In particular our motors are approved by: ABS, BV, DNV and RINa.
SAFETY
The whole series is supplied with PTC in windings and internal water leakage sensor as standard.
SOUND LEVELS
The electric tables show the sound pressure levels (Lp(A)) measured at no load conditions at one metre distance from the machine according to standard ISO R1680 with tolerances of 3dB(A). The values do not depend on the supply frequency.
1: Suitable for B3 mounting
On request high load configurations are also available: roller bearings or sleeve bearings.
