NMK 560L6A 2800 KW 6000V ABB high voltage induction motors 992 rpm 50HZ

ABB's engineered motors for low voltage variable speed drives range of up to 2240 kW. Modular slip-ring motors, type NMK Availability for heavy load inertia applications Slip-ring motors are an ideal solution for applications which require high starting torque and low starting current. They are especially suitable for heavy load inertia applications like mill drives or situations where network conditions are weak.

ABB’s slip-ring motors minimize mechanical stress at starting, increasing the lifetime of your driven equipment. They provide maximized availability and high torque over the entire speed range. Slip-ring motors are widely used in mills, crushers, fans, and conveyors in the mining, cement and metal industries. In addition, these motors offer a reliable solution for pumps in the water industry and safe area pumps, compressors and mixers in the petrochemical industry. NMK slip ring motors are available in shaft heights from 400 to 710 mm, with cooling methods and protection types of IC611/IP55, IC81W/IP55 as standard. The motors are rated up to 10,000 kW. NMK motors have a welded steel frame. Slip ring unit can be supplied with permanent contact brushes, or with brush lifting gear. In both cases the slip rings are enclosed in a housing located at the N-end and separated from the main motor frame. Liquid resistance starter(LRS) is available on request. For NMK motors this catalog only shows the typical technical data of 6kV and 11kV at 50 Hz for 4, 6, and 8 pole motors. While the complete product scope covers motors with 60Hz, pole numbers up to 16, and voltage rating up to 13.8kV. For more detailed technical data and configuration solutions on NMK slip-ring motors, please contact ABB. Standard combinations for NMK motors are IC611/IP55 and IC81W/IP55, other cooling methods of IC616, IC86W, etc. available on request. IC611/IP55 This design has an air-to-air heat exchanger mounted on the motor, which is fully enclosed. Shaft mounted fans are fitted both inside motor frame and inside slip ring housing, 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 The machine is totally enclosed having a machine-mounted and a SRU housing mounted air-to-water heat exchangers. A shaft mounted fan is fitted inside the casing to supply the internal cooling circuit. The motor is protected against dust and splashing water from any direction.a component designed for this purpose and mounted directly on the rotor of the main motor, or by a fan or pump unit mechanically driven by the rotor or the main motor. The type designation of the NMK motors follows the coding principle shown below.
