My suggestion to Enrico was to pull the driver transistors that switch
between the +24 and the motor windings. If his case is usual there are
three of these (often Darlingtons). If the board still smokes when
power is applied, you know that the fault does not lie in the motor nor
in the driver transistors.
I received no response, FWIW.
