Description
B5H is the medium-voltage part of the industrial series A_C–B_C/B5H: closed asynchronous motors with external fan cooling of a finned cast-iron housing (IC411; variants IC410 without fan and IC416 with an independent fan). This design is the most common type of medium-power high-voltage motor for pumps, fans and compressors, and requires no heat exchangers or water supply system. According to the series page, the A_C–B_C/B5H range covers powers up to 2,400 kW and voltages up to 11,000 V, frame sizes 71–560 mm, 2–16 poles, frequency 50/60 Hz or variable-speed operation. Degree of protection IP55, IP56, and up to IP65 for cast-iron housings. Ambient temperature −55…+60 °C, which allows use in cold climates. Rolling bearings, sliding bearings from frame size 355. Standard IEC 60034. Specific power and frame limits for the medium-voltage B5H are not given on the website; the low-voltage series A5C, A6C (aluminium) and B5C, B6C (cast iron) are listed as separate items. Main options: PT100 temperature sensors, anti-condensation heaters, special voltage, preparation for vibration sensors, neutral terminals in a separate box, insulated bearing and earthing brush, lubrication system for sliding bearings. Application areas: cement, chemical, metallurgical, mining, pulp and paper and sugar industries, power generation, water pumping and treatment. This item is an analog of closed, externally ventilated 6–10 kV high-voltage motors of the 4AZM, A4 and DA304 series.
