ABB Process Performance Motor
ABB motors are of the totally enclosed, three phase squirrel cage type, built to comply with international IEC and EN standards. Motors conforming to other national and international specifications are also available on request.
All production units are certified to ISO 9001 international quality standard as well ISO 14000 environmental standard and confirm to all applicable EU Directives.

Stator
The motor frames including feet, bearing housing and terminal box are made of cast iron. Integrally cast feet allow a very rigid mounting and minimal vibration. 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 motor mounting. In the basic design, sizes 71 to 132 are supplied
without drain holes, although these can be provided as an option.
Motor sizes 160 to 450 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.
Drain holes
Motors can be supplied for foot mounting, flange mounting and combinations of these.
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, please mention variant code 066 when ordering. See variant codes 065 and 066 under the heading “Drain
holes”.
Motor sizes 71-132 : As standard without drain holes.
Motor sizes 160-450 : As standard with drain holes and closable plugs.
Bearings
The motors are normally fitted with single-row deep groove ball bearings.If the bearing at the D-end is replaced with a roller bearing (NU- or NJ-), higher radial forces can be handled. Roller bearings are suitable for belt drive applications. When there are high axial forces, angular-contact ball bearings should be used. This option is available on request. When a motor with angular-contact ball bearings is ordered, the method of mounting and direction and magnitude of the axial force must be specified. For special bearings, please see the variant codes.
Lubrication intervals
ABB follows the L1-principle in defining lubrication interval. That means that 99% of the motors are sure to make the interval time. The lubrication intervals can also be calculated according to the L10-principle, which are normally doubled compared to L1-values. Values available from ABB at request.
Bearing life
The nominal life L10h of a bearing is defined according to ISO 281 as the number of operating hours achieved or exceeded by 90% of identical bearings in a large test series under certain specified conditions. 50% of the bearings achieve at least five times this figure. The calculated bearing life L10h for power transmission by means of a coupling (horizontal machine): Motor sizes 280 to 450 ≥ 200,000 hours. On delivery, the motors are ready lubricated with high quality grease. The recommended grease used can be seen from ABB's Low Voltage Motors Manual delivered together with the motor or for frame sizes 160 - 450 from the lubrication plate fastened to the motor frame.
Motors with permanently greased bearings
Standard versions of frame sizes 71-132 are equipped with closed bearings, type 2RS1. Also
motors with frame sizes 160-250 can be equipped with permanently greased bearings. Bearings are lubricated with high quality, high temperature grease. Bearing types are mentioned in the rating plates.
Lubrication method in cast iron motors
• M2BA 71-132 Permanent greased bearings as standard
• M3BP 160-450 Regreasable bearings as standard solution
• M3BP 160-250 Permanent greased bearings as an option
Motors with re-lubrication nipples
For sizes 280 to 450 the bearing system has been built so that a valve disc can be used to ease the lubrication. Motors are lubricated while running. Grease outlet opening has closing valves at both ends. This should be opened before greasing and closed 1-2
hours after regreasing. After lubrication close the valves. This ensures that the construction is tight and dust or dirt cannot get inside the bearing.
