Cast Iron Motors M3000, 160-400 Status January 2003; What is new in M3BP355 and 400?
Cast Iron Motors M3000, 160-400 M2BA 160-400 M3BP 160-400
Reliability • Rigid frame and end shields • FEM analysis of all parts • Avoiding resonance frequencies • Vibration resistant • Integral cast feet • Strong bearing assembly • Improved cooling • More possibilities for customer solutions: • Place for external PT100 for bearings as standard • Brake fastening points (280-400) • Improved vibration monitoring • 4 different positions for grease or SPM nipples (280-400)
Reliability • Longer bearing life time • Regreasable bearings • Locked bearing in D-end • High temperature grease as standard • 63-series bearings • Valve disc to prevent overgreasing • Improved cooling; lower bearingtemperature -> longerlubrication interval • Longer winding life time • Low temperature • Class F insulation • Class H impregnation varnish • Phase insulation as standard • Double-insulated copper wire
M3BP 355 & 400 • New bearing sizes • Longer re-lubrication intervals in 2-pole motors • Better spare part availability Motor Bearing D-end Bearing N-end M3BP 355 2 p 6316M C3 6316M C3 M3BP 355 4-12 p 6322 C3 6316 C3 M3BP 400 2 p 6317M C3 6317M C3 M3BP 400 4-12 p 6324 C3 6319 C3
Reliability • Improved sealing • IP 55 as std. • gamma ring (160-250) • Inner bearing cover sealing improved • Labyrinth seal with felt at D-end as standard in 2-pole motors (280-400),4-12 pole motors 315LK, 355, 400 • Axial sealat D-end (V-ring) as standard in other types;4-12 pole motors 280SM, 315SM, 315ML
Easy maintenance • New re-greasing plate from size 280 • Long re-greasing intervals • now even longer • Re-grease during operation • Grease through the bearing • Easy access to grease nipples • Wider grease channel
