Description
B_JH are medium-voltage asynchronous motors with a water jacket on the housing (IC71W cooling method). Heat from the active parts is removed through the stator walls by circulating water, so the motor has no external fan and no heat exchanger; it is compact, quiet, and does not release heat into the room. Such motors are convenient for installation in confined machine rooms, under the deck, in underground pumping stations and in rooms with limited ventilation. Parameters: power up to 3,500 kW (series announcement on the website: up to 4,000 kW), voltage up to 6600 V, frequency 50/60 Hz or variable-speed operation, 4–14 poles, frame sizes 315–630, degree of protection IP55 or IP56, ambient temperature −20…+60 °C, cooling water temperature up to 50 °C. Welded steel housing, rolling bearings, sliding bearings from frame size 355. Standard IEC 60034. The low-voltage B_J version is listed as a separate item. Applications according to the manufacturer cover both industry and fleet: cement and metallurgical industries, mining, power generation, pulp and paper and sugar production, water pumping and treatment, as well as propulsion units, azimuth thrusters, dredge ground pumps, hybrid machines and PTO/PTI systems. The series is listed on the website in the hydropower, fleet and industry sections.
