When placing an order, please state the following minimum data in the order, as in the example. The product code of the motor is composed in accor- dance with the following example.
Technical data for totally enclosed squirrel cage three phase motors IP 55 – IC 411 – Insulation class F, temperature rise class B IE2 class
Motors that will be operated in very humid or wet environments and especially under intermittent duty should be provided with drain holes. The appropriate IM designation, such as IM 3031, is specified on the basis of the method of mounting the motor. Motors are provided with closable plastic plugs in the drain holes (see diagram below). The plugs will be open on delivery. When mounting the motors it should be ensured that the drain holes face downwards. In the case of vertical mounting, the upper plug must be hammered home completely. In very dusty environ- ments both plugs should be hammered home. Sizes 56 to 63 are supplied as standard with drain holes on D-end while sizes 71 to 280 are supplied with drain holes both on D-end and N-end.
Single-speed motors of size 56 to 132 are stamped with 50 and 60 Hz at voltage code S and D. The current rating for each voltage range is specified on the rating plate. It represents the highest current that can exist within the voltage range at the rated output. The power factor and speed specified on the rating plate apply at 400 V 50 Hz and 460 V 60 Hz. M3AA 280 has feet and D-end shield of cast iron. M3AA 250 SMB 2-pole, high output version, as well as M3AA 280 2-pole have cast iron feet and bearing shields. The flange bearing shields of sizes 180 to 280 are made of cast iron Axially-locked bearings
The terminal block is provided with 6 terminals for connecting Cu-cable. The terminals are marked in accordance with IEC 60034-8.
Single-speed motors of size 160 to 280 are stamped with 50 and 60 Hz at voltage code S and D. The rating plate is arranged in the form of a table with values for current, power factor and motor speed at six voltages.

Motor frame The motor frame is made of aluminum, and the standard design includes aluminum feet for motor sizes 71-180, cast iron feet for motor sizes 200-280. Drain holes Motors that will be operated in very humid or wet environ-ments, and especially under intermittent duty, should be provided with drain holes. The IM designation, such as IM 3031, determines the intended mounting arrangement for the motor. Motor sizes 71 - 280 are fitted with drain holes and closable plugs. The plugs are open on delivery. When mounting the motors, ensure that the drain holes face downwards. In the case of vertical mounting, the upper plug must be hammered home completely. In very dusty environments, both plugs should be hammered home. When mounting arrangement differs from foot mounted IM B3, mention variant code 066 when ordering. IP 55 - IC 411 - Insulation class F, temperature rise class B 0.12-0.75kW, Grade 3 according to GB 25958-2010. 0.75-90kW, IE2 efficiency class according to 60034-30-1; 2014 , Grade 3 according to GB 18613-2012.
The other 55 motors on fans, compressors and pumps, as well as 5 frequency converters, have also achieved remote status monitoring. The factory can remotely monitor the operation and health of the entire drive system through an integrated one-stop portal. These status data help optimize system efficiency and plan maintenance activities based on actual needs rather than generic schedules. In addition, this can reduce maintenance costs and avoid unexpected downtime.
ABB provides complete IE3 series standards, flameproof (Ex db and Ex db eb), increased safety (Ex ec) and dust ignition protection (Ex t) motors to meet the requirements of national customers covering these types of motors according to the minimum energy performance standards (MEPS).
