Naval and Marine Duty Motors


Shipbuilding is a complex activity involving the use of various machinery during manufacturing as well as while being fitted in the ship itself. A large number of motors are used in all such machinery. Reliable operations of these motors gain priority as they have to demonstrate peak, flawless performance while in the high seas. These motors are constantly in a saline atmosphere and have to operate for long hours, rather, continuously. Also, the motors are specially designed to withstand heavy vibrations and shocks during take-off and landing of aircrafts from warships. Under such conditions, the robust performance of electric motors is extremely important.
LHP is well-known for its Naval and marine duty motors and has been supplying large quantities to the Indian Navy, other commercial shipbuilders and ship maintenance agencies, for several years. Our range includes up to 1000 kW (450 frame) in energy-efficiency versions (IE2, IE3 and IE4). For a few special applications, we also supply Flame-proof (Explosion-protected) electric motors.
All of our Naval and marine duty motors comply with the standard EED-Q-71-R4. Shock Graded Motors are suitable for NSS I and NSS II shock grades as per EED-Q-071 (R3/R4) & JSS 55555:2000, MIL-STD-461 E/F.
