  1. Cast Iron Motors M3000, 160-400 Status January 2003; What is new in M3BP355 and 400?

  2. Cast Iron Motors M3000, 160-400 M2BA 160-400 M3BP 160-400

  3. 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)

  4. 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

  5. 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

  6. 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

  7. 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

  9. Traceability, Safety, and Noise • Stainless rating plate • laser engraved (280-400), long lasting • with individual serial number • More lifting possibilities: • More places for lifting eyes • Additional holes in feet canbe used for lifting (280-400) • Low noise level • Improved fan design (355-400) • Low magnetic noise • Expertise in electrical design andsuperior electrical steel • No loudspeaker effect • fan cover fastened with rubbervibration dampeners

  10. Easy Installation & Service • Large terminal box • All terminal boxes 4x90° • Cable entry flange from size 160 • Same terminal box at side andtop (280-400) • New terminal board from size 280 • Easier to connect • Cables from any direction • Cable lug bolts prefixed • Rubber seal under terminal block • Improved short-circuitresistance Updated 21.01.2003

  11. Easy Installation & Service Frame sizes 355-400 • New adapters available • E  2D (Similar to MPMM-ZL1), Code 3GZF294730-944 • New adapter E  D, Code 3GZF294730-944

  12. Easy Installation & Service • Accessories • Lead-through to separate terminal box or bearing monitoring through intermediate flange • All monitoring equipment connections at main terminal box • More possibilities for customer solutions: • Auxiliary terminal boxes can be installed after delivery • Closed key way (160-250) • Open key way (280-400) • Simple and reliable fan assembly (key) • No special tools required • Improved transport locking

  13. M3BP 280 - 400 Side mounted terminal box More efficient space usage: Enlargement of the cable channel does not increase outer dimensions. New design for side mountedterminal box More space for connection cables Terminal box located vertically: - 4x90° turnable - Possibility to connect with rigid armour More space between “floor” and the terminal box

  14. Flexibility • Variable Speed Drive • Stock motor below 100 kW suitable for VSD, UN 500 V • Shaft prepared for encoder as easy modification • Improved separate cooling • easy modification • smaller fan motor • lower noise level • Improved winding design for VSD • Insulated bearings above 100 kW • Flexible in design for modification of/to • Tacho mountings • Separate cooling • Brake • Marine

  15. M3BP 280 - 400 New fans • New series of plastic and metal fans • Easier to mount/dismount (no puller needed for plastic fans) • Series of aluminium fans easily changeable with full-plastic fans • Same fans as in standard motors used with separate cooling • Smaller fan and fan motor • Lighter rotating masses and better balance • Light and quiet construction

  16. M3BP 400 Installation dimensions Better compatibility with other ABB products as well as products from other manufacturers M3000 standard dimensions (Also standard dimensions for example in HXR400, Siemens) Dimensions according to IEC-standard available in M3BP400 on request. (M2BA400 standard dimensions) Diameter of flanged endshield 1000mm (800mm on request )
