    I have a problem with the Baumuller Motor on our Heidelberg MO
    The motor is overheating and the thermal cut-out is activated after 2-3 hours of use.

    My electrician has inspected the motor and all seems ok :
    internal fan extracting ok
    brushes new
    commutator good
    brake releasing correctly

    However the motor star/delta connection seems incorrect. It seems to be in a Delta connection (200v) at the moment but should be in a star connection (380v) as the machine has a 380v supply.

    I am unsure if the connection is correct and how the configuration of the bridging plates must be to change it to a star connection, if it is delta at the moment. (pls see attached photos)

    Motor details: (pls see attached photos)
    D type
    Type : RDNX 27Z-L4
    Nr: 92101515

    Any assistance / advice is greatly appreciated.
