PICK UP  UNIT

2. Disassemble Motor Assembly and conduct final inspection and testing. 

3. REWINDING OF STATOR 

• Take note of winding data 

• Strip-out old wires. 

• Clean stator core 

• Conduct Stator Ring test.  

• Apply red Glyptal insulating paint on stator core surface. 

• Lay-out NOMEX insulating material into stator slots. 

• Rewinding using heavy armored magnetic wire 

• Varnishing using class F Imported varnish.  

• Oven bake to dry Stator core 

• Encapsulation of Stator windings (Application of Epoxy) 

• Clean excess varnish. 

4. RECONDITIONING OF ROTOR ASSEMBLY 

• Conduct Growler testing on the Rotor core to check if the Rotor bars are grounded. 

• Check rotor alignment particularly both shaft ends to check if the shafting is bended or not. 

• Clean Rotor to remove Grease, Dust and Carbon. 

• Oven bake to dry Rotor Assembly. 

• Dynamic Balancing if necessary. 

• Apply Red Glyptal Non – conductive insulating paint to restore core. 

• Remove old Bearings  

• Install new Bearings (Ball Bearings) 

• Check Bearing housings and Journals to verify worn – out services  

5. Assemble Motor and Painting
