Type designation example - LAKC 4355A: |
|
• LAK = Type of Motor • C = Compensated • 4 = Number of poles • 355 = Center height • A = Core Length |
|
The LAKC motors are designed for use in heavy industry where there is a need for reliability, 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 • Armature windings welded to the commutator and vacumm impregnated with 100% fill resin for optimal reliability • Internal cooling ducts in the armature with under commutator cooling • Generously dimensioned shaft and bearings • End shields of square design with large opennings to facilitate brush accessability for maintenance • Spigot at the non-drive end for mounting of tachometer, encoder etc. • Split brushes |
|
The fully laminated compensated LAKC d.c. motor ensures: • High overload capacity with linear torque/current characteristics • 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 |
