N-series configured to order motors combine cost-efficient standardized designs and short lead times with safety, productivity, energy efficiency and reliability — High voltage configured to order motors Technical catalog High voltage configured to order motors Technical catalo

High voltage configured to order 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.

ABB reserves the right to change the designs, technical specifications and dimensions without prior notice. Data presented in rating lists are typical values. Accurate motor data will be given on request at the quotation phase. All ratings in this catalog are designed for the following: - Class F insulation / Maximum temperature rise of 80K by resistance - 40 °C ambient - Altitude of 1000 meters or less

— High voltage configured to order motors N-series High voltage configured to order 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 configured to order motors: rib cooled motors (type NXR), modular induction motors (type NMI). With their standardized designs and short lead times, the N-series high voltage pre-engineered motors meet most common needs across a wide range of...

— 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 characteristics....
