LAKC 355-560 DC Motors - T-T ELECTRIC - #3

Text version of the page

Introduction The LAKC motor range of d.c. motors are fully laminated with compensated shunt windings and comprises 4, and 6 pole machines. Output : 300 - 1300 kW Torque : 4000 - 23000 Nw LAKC Range Type designation example: LAKC 4355 A: LAK = type of motor C = compensated 4 = number of poles 355 = frame size A = core lenghts Design and characteristics The LAKC motors are designed for use in heavy industry meeting the tough requirements for high realiability, low maintenance costs, good commutation, long brush life and low energy consumption. • Fully laminated stator yoke, main poles and interpoles. • Pole face compensation winding to enhance performance in overload conditions. • Excellent commutation due to well proportioned ratio between armature length and diameter with low bar to bar voltage. • High thermal time constant. • Class H insulation. • Armatures wound with high quality materials. • Vacuum impregnated armature windings with 100% fill resin for optimal reliability. • Generously dimensioned shaft and bearings. • End shields of square design with large openings to facilitate brush accessability for maintenance. • Spigot at the non-drive end for mounting of tachometer, encoder etc. • Twin brushes. Advantages The fully laminated compensated LAKC d.c. motor ensures: • High overload capacity with linear torque/current characteristic. • High efficiency due to low field losses and well proportioned air gaps between armature and stator. • Excellent commutation over the entire speed range. • Long brush life. • Low noise level. • Class H insulation. • Class F temperature rise. • Excellent dynamic response, enhanced by superior transient commutation. • Easy access to brushes and commutator. • Custom built to meet individual specifications. 3 Frame Poles Core size lengths 355 4 A, B, C 400 6 A, B, C 450 4 A, B, C 500 6 A, B, C, D 560 6 A, B, C, D
