Hi Philip,
may be, but I would chose the safe side (We did with our 6.270 board and used 2
diodes, who cares about 2 diodes).
BTW I'm not sure what happens with the energy in an electro motor. I can
imagine that this energy (resulting in a magnetic field) is used to turn the
anchor (is it the right word in english for the part that turns in a electro
motor ? :-) ). But I have no knowledge of the behavior of electro-motors.
