— High voltage general purpose motors N-series High voltage general purpose motors from ABB combine cost-efficient standardized designs and short lead times with safety, productivity, energy efficiency and reliability. They are targeted at applications where a highly customized motor is not needed. This catalog covers ABB’s N-series high voltage general purpose motors: rib cooled motors (type NXR), modular induction motors (type NMI) and slip-ring motors (type NMK). With their standardized designs and short lead times, the N-series high voltage pre-engineered motors meet most common needs...

— Rotor and stator Rotor The key to a long rotor operating life is minimal vibration. This is achieved through robust construction and careful balancing. ABB selects the shaft material according to the demands of the application and the ambient conditions in which the motor is to operate. Squirrel cages are made of copper, copper alloy or aluminum, depending on the load and customer requirements. Additional stiffness is provided by fabricated rotor bars, which enable the motors to withstand long periods of heavy use. Aluminum bars and end rings are used to ensure optimal starting...

Horizontal motors Horizontal motors in frame sizes 315 to 560 have deep groove ball bearings at both ends. The NMI 630 has a double bearing arrangement (a deep groove ball bearing and cylindrical roller bearing) at the D-end and a cylindrical roller bearing at the N-end (only horizontal motor available). The bearing at the D-end is axially locked in horizontal motors. Standard bearings for horizontal motors are listed in the table below and the bearing construction is shown in the figures on page 12. The standard bearing solution is designed to carry the weight of a typical coupling half...
