MG Drive Unit Reverse Engineering

[Jack Bauer]

One of the big projects I've worked on this year has been the MG drive unit. I'm not 100% sure which exact models and years of MG vehicle use this exact unit but am fairly sure the newer ZS and 5 are amongst them. It also "look" like some of the other drive units MAY use a similar control board but this has not been confirmed as yet.

I'm pleased to say that the V2 OpenInverter board now runs the drive unit in full FOC closed loop mode on the bench. I also have purchased a 2003 Volvo V70 to use as a test bed.

Anyway, for those interested here are some links and videos:

Guess this was a giant waste of time then...

I think it's an idea who's time will come, it's a neat unit, almost an electric diff it's so compact and I'm seeing plenty of MGs on the road so they should soon be plentiful and cheap at the breakers. Perhaps it will take off when we all come out of hibernation in the spring.

What kind of power does this driveunit make?

Do you have some basic dimensions for the drive unit? I'm wondering how easily it would fit in the subframe of a RWD car.

Can I get the firmware, please?
