The ABB NEMA cast iron Motors are ideal for serial OEMs who require a standard product with electrical and mechanical properties that do not need to be altered. These ABB NEMA Process performance cast iron Motors are designed for pump, fan and compressor applications. ABB supplies a full range of NEMA Motors. All motors are equipped as standard with an axially-locked
bearing at the D-end.
The bearing's outer ring is tightly locked between bearing's
covers and the housing fit.
Transport locking
Motors with roller bearings are fitted with a transport lock
to prevent damage to the bearings during transport. All
high voltage motors are fitted with a warning sign when the
transport lock is fitted to prevent operational damage and
alert operators.
Locking may be fitted in any other situations where the
transport conditions are considered as potentially damaging.
Basic version with deep groove ball bearings Version with roller bearings, variant code 037
If the bearing at the D-end is replaced with a roller bearing
(NU-), higher radial forces can be handled. Roller bearings are
suitable for belt drive applications.
The N-end bearing is axially free and can take the thermal
expansion. Note! NU-bearing is axially

Type Description

M3BM motor catalog ratings can be re-stamped as follows. Motor construction will not be changed but a new rating plate and data sheet can be created with variant code 002. In all the below cases or their combinations, please contact ABB for correct motor size and motor data. Bearing re-lubrication intervals as shown in this catalog are valid also for re- stamped motors. Output Output can be re-stamped downwards from the catalog data. Voltage Voltage can be re-stamped downwards up to 10% from the motor nominal voltage in the catalogue. Motor output has to be de-rated so that the motor absolute temperatures will not be higher compared to catalog data. Ambient temperature Motor can be de-rated to higher ambient temperature. Maximum ambient temperature is 55 °C. The output has to be de-rated so that motor's absolute temperatures will not be higher than the catalog data. Altitude Motor can be de-rated to higher altitudes than standard 1000 meters above sea level. There are different maximum altitude limits for different motors depending on voltage level. The motor output has to be de-rated so that the absolute temperatures of the motor will not be higher than the catalog data.

The design of the motor reduces the ingress of rain, snow and airborne particles into the electrical parts. On the air intake path this is achieved by ensuring that the average velocity does not exceed 3 m/s, allowing any heavier particles to settle. The design of air intake path includes three acute changes in excess of 90 degrees to further reduce the flow rate to the optimum level. The motor is protected against splashing water from any direction. IC611 / IP55 In this design the fully enclosed motor has an air-to-air heat exchanger mounted on the motor. Shaft mounted fans are fitted both inside and outside of the casing to supply the inside and outside cooling circuits respectively. The motor is protected against dust and splashing water from any direction. IC81W / IP55 This fully enclosed motor is fitted with an air-to-water heat exchanger. A shaft mounted fan is fitted inside the casing to supply the internal cooling circuit. Motor is protected against dust and splashing water from any direction. The terminal boxes have a protection of at least IP55. IC31 / IP55 This version is fitted with an inlet and outlet pipe to use remote cooling air. Essentially this is the AMI motor frame without any upper cover. The motor is protected against dust and splashing water from any direction. IC01 IC01 with asymmetric inside air circulation
