Description
Fulfilling Bureau Veritas (BV) requirements, with certificate Fulfilling Det Norske Veritas (DNV) requirements, with certificate. ABM’s Marine motors are widely used in the shipbuilding industries. MM series marine three-phase induction motors belong to the well known ABM M2000 family. The manufacturing technology is complying with the national standards, e.g. GB755“Rotating Machine Rating and Performance”and ZC steel marine vessels classification criterion. The motors are in conformity and certified by several international classification societies, such as ABS, BV, CCS, DNV, GL, KR, LR, NK, IEC. The MM motors are suitable for the use on marine pumps, ventilators, hydraulic machines, and other marine equipment.

Cable glands Glands as option
Fan Material Glass-fiber reinforced polypropylene
Fan cover Material Steel
Stator winding Material Copper Insulation Insulation class F. Temperature rise class B unless otherwise stated.
Totally enclosed fan cooled IP 55, IP56 or IP65. Special designed high sealed cable gland used at the cable entrance; there are two terminations for earthing, one at the terminal box internal and another one at the outside of the frame, to ensure the electric security throughly. High rigidity cast iron material to strengthen the resistance of mechanical impacting. As standard, terminal boxes are mounted at the top. Left side, right side are on request.Generally, Terminal box can turn 4 x 90°, very conveniently for use.
Reliable windings To ensure long lifetime, the winding is made from the latest available material in class F protection and temperature rise 95K according to the classification societies’ rules. If lower temperature rise, i.e. class B (70K) is needed, it is necessary to reduce the output range. As an indication the following formula can be used.
Balancing method Half key balancing as standard
Drain holes Drain holes with closable plastic plugs, open on delivery
Enclosure IP 55 Higher protection on request
Cooling method IC 411
Lifting lugs Integrated cast iron lifting lugs.
