Magnetic shaft sample received
We received your sample. Because you don’t know magnet material, metal shaft material, installing positions of bearings and accuracy requirement, our engineer needs time to test and figure out what materials for motor shafting.
We suggest use sintered neodymium magnet with grade N40SH according to conventional motor working temperature. This grade magnet can work under 150℃.
Due to Moisture climate in India, samples will be catching rust easily. We can use superior quality metal in shaft, such as SUS410 or SUS430 instead of 40cr steel.
In your sample, there are two ring magnets in the shaft; we will make one single ring. If you need better starting performance, it can be solved by magnetizing.
As per your sample, 500pcs, our unit price is xxx. Please feel free to contact us if you have any question for magnet order.
