1 BA Electrical Machines Insert image here Cast Iron Motors M3000, Status January 2003; What is new in M3BP355 and 400?

2 BA Electrical Machines Cast Iron Motors M3000, M2BA M3BP Cast Iron Motors M3000,

3 BA Electrical Machines Cast Iron Motors M3000, 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 ( ) Improved vibration monitoring 4 different positions for grease or SPM nipples ( )

4 BA Electrical Machines Cast Iron Motors M3000, 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 bearing temperature -> longer lubrication interval Longer winding life time Low temperature Class F insulation Class H impregnation varnish Phase insulation as standard Double-insulated copper wire

5 BA Electrical Machines Cast Iron Motors M3000, M3BP 355 & 400 New bearing sizes Longer re-lubrication intervals in 2-pole motors Better spare part availability Motor Bearing D-endBearing N-end M3BP p6316M C36316M C3 M3BP p6322 C36316 C3 M3BP p6317M C36317M C3 M3BP p6324 C36319 C3

6 BA Electrical Machines Cast Iron Motors M3000, Reliability Improved sealing IP 55 as std. gamma ring ( ) Inner bearing cover sealing improved Labyrinth seal with felt at D-end as standard in 2-pole motors ( ), 4-12 pole motors 315LK, 355, 400 Axial seal at D-end (V-ring) as standard in other types; 4-12 pole motors 280SM, 315SM, 315ML

7 BA Electrical Machines Cast Iron Motors M3000, 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

8 BA Electrical Machines Cast Iron Motors M3000, Easy maintenance Surface Treatment Corrosion category motor type Standard motor ChOG offshore Motor Fan cover Variant code 115 For corrosive environmental use Blast-cleaning Sa 2 1 / 2 2-pack epoxy primer 40  m 2-pack epoxy top coat 40  m  = 80  m Blast-cleaning Sa 2 1 / 2 2-pack epoxy primer 40  m 2-pack epoxy intermediate coat 2x40  m 2-pack epoxy top coat 40  m  = 160  m Blast-cleaning Sa 2 1 / 2 2-pack zinc rich epoxy primer 40  m 2-pack epoxy intermediate coat3x40  m 2-pack polyurethane top coat 40  m  = 200  m Galvanised coated steel Epoxy–polyester powder coat 80  m  = 80  m Galvanised coated steel Epoxy–polyester powder coat 80  m  = 80  m Galvanised coated steel Epoxy–polyester powder coat 80  m 2-pack epoxy intermediate coat 60  m 2-pack polyurethane top coat 60  m  = 200  m

9 BA Electrical Machines Cast Iron Motors M3000, Traceability, Safety, and Noise Stainless rating plate laser engraved ( ), long lasting with individual serial number More lifting possibilities: More places for lifting eyes Additional holes in feet can be used for lifting ( ) Low noise level Improved fan design ( ) Low magnetic noise Expertise in electrical design and superior electrical steel No loudspeaker effect fan cover fastened with rubber vibration dampeners

10 BA Electrical Machines Cast Iron Motors M3000, Easy Installation & Service Large terminal box All terminal boxes 4x90° Cable entry flange from size 160 Same terminal box at side and top ( ) New terminal board from size 280 Easier to connect Cables from any direction Cable lug bolts prefixed Rubber seal under terminal block Improved short-circuit resistance Updated

11 BA Electrical Machines Cast Iron Motors M3000, Easy Installation & Service Frame sizes New adapters available E  2D (Similar to MPMM-ZL1), Code 3GZF New adapter E  D, Code 3GZF

12 BA Electrical Machines Cast Iron Motors M3000, 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 ( ) Open key way ( ) Simple and reliable fan assembly (key) No special tools required Improved transport locking

13 BA Electrical Machines Cast Iron Motors M3000, M3BP Side mounted terminal box New design for side mounted terminal box Terminal box located vertically: - 4x90° turnable - Possibility to connect with rigid armour More space for connection cables More efficient space usage: Enlargement of the cable channel does not increase outer dimensions. More space between “floor” and the terminal box

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

17 BA Electrical Machines Cast Iron Motors M3000, M3BP 355 & 400 dimensions Dimension drawings in PDF-format Layout-models for designers in 2D and 3D formats DXF- files for 2D-CAD programs IGES-files for 3D Detailed information is available in ABB Library M3BP400L4 M3BP355ML4 M3BP355SM4 M3BP280SM4
