    Yep! The case side of the rotor has small magnet(s) for the halls.

    What kind of motor is this?

    Please pardon my motor tech ignorance lol. This is the parking pawl motor for a 2016 Nissan Leaf. It's marked 12v. Taking it apart: - 12 coils - Rotor is iron, non-magnetic. - The coils are connected to a common wire. - There are 3 drive wires for the coils. In the picture you can see how...

    Lebowski CANbus Protocol

    What I'm looking for is the CAN IDs for the messages it's transmitting, the message length in bytes of each message, and how to decode the messages (byte order, definition), etc. So for example (I'm making this up, but this is the kind of thing I'm looking for) - CAN ID 0x1234 Data Length: 2...

    Lebowski CANbus Protocol

    Haha oops! I’ve read through the manuals, but didn’t see the protocol definition. I’ll go through them again. Thanks

    Lebowski CANbus Protocol

    I've been searching for the protocol by which the Lebowski controller transmits / receives throttle and motor direction information, but have not found it (yet). Can someone point me to the manual or documentation that outlines it? Thanks!

    Arlo1 Inverter working with the TI resolver to encoder board

    Thanks! I’m putting the motor in an 81 Delorean. The OE transaxle is terrible - this will definitely improve drivability. I agree, it would be nice if the TI board was cheaper - it does seem to work well. Figuring out the firmware wasn’t too bad.

    Arlo1 Inverter working with the TI resolver to encoder board

    This is my first post here. Back in January I bought some boards and IGBTs from Arlin and set about to assemble his inverter design. I bought a 2016 Leaf motor assembly to work with it. Fast forward a few months and everything is working nicely. I decided to use the Texas Instruments PGA411Q1EVM...
