Description
Class 155 (F) insulation used at 130 (B), or 180 (H) used at 155 (F), leaves a thermal margin. The protection rating is IP55, IP56, IP65 or IP66, cooling is IC411, IC410, IC416 or IC418, and mounting is B3, B5, V5, V6, V1, V18, B14 or B35. Water-cooled motors of 13.5–400 kW, shaft heights 160–355, 2 and 4 poles, work without a fan, so they are quiet and compact. Axial ventilation and non-ventilated versions cover 0.12–630 kW, and without a fan the power is reduced. An independent axial fan for 2.2–700 kW and shaft heights 132–450 is needed for low speeds from a VFD. Explosion-proof add-on brakes have a torque of 4–1200 N·m at shaft heights 71–280, motors with a built-in brake are 0.18–7.5 kW, and with incremental encoders 0.18–400 kW. The motors are used in the oil and gas, chemical, pharmaceutical and food industries, at grain elevators and mills, treatment plants and gas facilities. The item is an analog of the explosion-proof series AIM, VA, 2V.
How to choose
First determine the zone. For gas, II 2G Ex db eb IIC(B) T4 Gb or Ex db is taken, and for combustible dust II 2D Ex tb IIIC T120 °C Db. Then the design is chosen by duty: water cooling for a quiet compact machine of 13.5–400 kW, an independent fan for low speeds from a VFD, a brake or encoder if needed. If general-purpose motors or an Ex ec/tb version up to 400 kW are needed, see the W, WE and WXF series, and for wound-rotor crane motors of 45–1800 kW there is a separate line.

FAQ
What types of explosion protection does this motor have?
II 2G Ex db eb IIC(B) T4 Gb, II 2G Ex db IIC(B) T4 Gb and II 2D Ex tb IIIC T120 °C Db. ATEX, IECEx, CCC certificates.
What power and voltage are the motors made for?
The base series covers 220–690 V and 0.12–700 kW, shaft height 63–500.
Can the motor be powered from a frequency converter?
Yes, the range is suitable for operation from a VFD. For low speeds there is a version with an independent axial fan for 2.2–700 kW.
How does the water-cooled version differ from the non-ventilated one?
Water cooling for 13.5–400 kW gives a quiet compact motor without a fan. The non-ventilated version for 0.12–630 kW works at reduced power.
