Alternating current generator rotor |
摘要 |
A rotor for an alternating current generator of the Lundell type. The rotor shaft carries two segments which have interleaved pole teeth. The rotor has a core member and a field coil disposed about the core member. The segments and/or core member are formed of compressed powder iron particles having a particle size in a range of about 10 to 250 microns. In the manufacture of the core and/or segments the iron powder particles are coated with a thermoplastic material and this thermoplastic coated iron particle material is compacted in the molding dies of a press. After compaction to the desired shape, the part is sintered at a temperature of about 2050 DEG F. to burn-off the thermoplastic material that coated the iron particles.
