MJBM/MJHM, MJRM/MJHRM, MJVM/MJHVM — marine synchronous generators up to 15 kV, up to 12,000 kVA

Description

Marine synchronous generators are produced in three series that repeat the industrial platform: MJBM/MJHM with open IC01 ventilation, up to 12,000 kVA (announced: up to 11,000 kVA); MJRM/MJHRM with air-water cooling, up to 11,000 kVA; and MJVM/MJHVM with air-air cooling, up to 5,500 kVA. The letter H in the designation indicates medium voltage. The company has worked in the marine sector for more than 130 years with integrators, shipyards and shipowners. Parameters of the base series MJBM/MJHM: voltage up to 15,000 V, frequency 50 or 60 Hz or variable-speed operation, 4–12 poles, frame sizes 315–1250, degree of protection IP23 (up to IP44 with filters), ambient temperature −15…+60 °C. Voltage regulator: E-Vo up to frame size 630 and D-Vo Light above for low voltage, and D-Vo Light for medium voltage. The generators are supplied with a Marine Survey Certificate and comply with IEC 60034-1, BS 4999-5000 and NEMA MG 1.32. Applications: auxiliary diesel generators, shaft generators, hybrid machines (engine-generator), variable-speed generators, offshore facilities, and PTO/PTI systems (power take-off and power take-in on the shaft line). Main options: PMG pilot exciter, flanged shaft for direct connection to the flywheel, reinforced construction for vibration, air filters, raised feet, neutral current transformer, insulated bearing, 64R protection and vibration sensors. For Ukraine the item is of interest for shipbuilding and ship repair, floating power stations, and generator sets that require certification by classification societies.
