Part Number: DRV425EVM
Other Parts Discussed in Thread: DRV425

Hi Team,

A customer needed help in bus bar calculation. The application has a 15mm thick bus bar and the calculator available on our site only goes up to 12.7mm

The "Bus bar" and "3-Phase" tab has similar restriction.

Can you please help?

Thank you and regards,

Marvin

Hello Marvin,

We had placed a limit on the calculator as we did not run simulations past that number. You can quickly simulate using using the FEMM simulations tool to see if it will work. Please remember the DRV425 saturates at about 2mT. You will need to download FEMM software.
