hi,

i'm using a microcontroller to run an old hard disk.i wrote the program myself,though it is very basic it works.i need a driver for both delta as well as star connection.

requirements:1)12V output;2)upto 40amps current capacity(for another motor).3)both delta and star,its okay even if they are separate circuits.

thank you.

Basically, the circuit will be the same for both star and delta connection. But obviously you need the current capability.

For a hard-disk motor you could try three power MOSFET drivers. These will have at least 1A sink and source current and a logic-level input.

For a star connection, the star point is normally not connected to anything (else).
