This investigation compares the electromagnetic performance of Fe-P-based SMC and Fe-5.0 wt.%Si powders for low-speed electric vehicle applications, suggesting optimal forming conditions.
Key Points
Somaloy 700HR 5P showed superior motor performance stability compared to Fe-5.0 wt.%Si, despite the latter's better powder state attributes.
Fe-5.0 wt.%Si displayed ~10% higher electromagnetic performance but a significant 19-25% decline in motor dynamo performance.
Taguchi-based simulations informed optimal forming conditions, focusing on density distribution, forming temperature, and speed.
Somaloy 700HR 5P achieved greater average density, leading to improved motor performance consistency despite its relative density variation.
