MOTORS FOR HEAVY ELECTRICAL VEHICLES

2.3. Electrical silicon steel non oriented

The following components are separated into one group for electric silicon steel non oriented:
1. Stator lamination
2. Rotor lamination
3. Resolver rotor/stator
These laminations are shrink fitted to respective components and can be separated by using heat

2.4. Stainless steel

1. Cooling pipe and connectors

2.5. Nodular cast iron

1. DE-shield

2.6. Aluminum

1. Stator frame
2. Rating plates
3. NDE shield
4. Rotor end plates/rotor fan

2.7. Copper

Copper is mostly integrated in the actual components and require some effort in order to be separated.
There are some special tools available to help separation but normally wedges, large hammers, gas
burners and manpower is used.
The following components are separated into one group for copper:
1. Stator winding
2. Stator connection
3. Resolver winding
