530kW motor checks? !!

Former Community Member
Former Community Member
Hello to all, and I do hope that people can advise me on this?


Firstly: what checks can I best do for a possible purchase of a single ABB - AMB 630 LC16 ABA C 530kW pump unit, which is unable to be properly tested (powered up) as the plant it was operating in has been decommissioned, and is currently being scrapped.


The unit appears to be mostly self contained, with a separate 'powercap' capacitor cabinet.

There are 8 in total, in various conditions and all look like this:

Secondly: No switching gear is 'included', however I could always ask the company (who's pulling the site apart) if it's possible to obtain the original starter systems maybe???

But would this be a good idea, considering again it's in an unknown condition.


From the 8 available, I've selected 2 that appear to be the most suitable for hopefully reusing again (not bashed about, leaking oil etc) and thus generally look ok, so possibly from that can choose the final one.... but it would be great to know how best to maybe pick the best from any testing that could be done where they stand now, without any power.


Obviously with big industrial machine as this, it's not your average consumer second-hand electrical goods....

....that one just plugs in, and then hopes it works when power is applied!



(Thanks in advance to any replies)

    That TigerTek motor test video was fun. As is their multi-level starter. very sensibly it looks as if they do all the switching  at LV - hence the 208 phase to phase rising to 585 phase to phase as the max setting. The HV side (1k8 phase to phase rising to presumably 6k6 but the top HV label is missing) is presumably a fixed ratio transformer.

    To start an unloaded motor at 1/3 of the volts in this way is a sensible precautionary approach. But the ratchet straps do look a bit weak. I also remember being told by Rolls Royce engineers never to stand to the side of any engine under test, nor directly behind it, as mostly things either come out at a tangents sideways, or straight out the back.

    If it does fail the safest place to be is not in the building, but failing that, some way off, at at about 45 degrees to the axis.
