    Ancient single phase electric motor - reversing the rotation

    Morning Gents, I hope that you can help me with this problem. I am not an electrician - I just know enough to be dangerous. I recently bought this beautiful beast : It's a Denford tools Viceroy pillar drill from the 60s or maybe even the 50s. Nice and cheap with one catch - it had a non...

    phase rotation testers

    anybody use them. my jtl training advisor wants me to check phase rotation of motors for portfolio. i don't see the point. the only motors we use are for fans and vsd driven so you can see what way they spin. i thought fair enough if there not expensive ill have a look but at £100 ill pass

    Phase Rotation

    Does it need to be correct?, Because we recently whent to a job and stuck on one of the consumer units was a sign saying 'Phase Rotation Incorrect'. As I'm still an apprentice I don't know about the test, and No one I asked has ever done one, So Does it not matter that it is wrong? Or is the...

    Voltage Optimisers.

    Has anyone come across a phase sequence fault when switching on a voltage optimiser for the first time. The system is a cheap chinese one I think with terrible instructions. Can a voltage optimiser know if your input wiring is black, grey, brown instead of Br, Bl, Gr? I ask because we don't...
