Permanent Magnet Open Frame Motor

Ok...I'm not a motor guy...but had a thought and wondered if it might have value...

For the sake of argument...let's say you cut the field coil off a Lionel open frame motor. In its place you place a permanent magnet of a shape that would fit on the motor frame, of a magnetic field-strength equivalent to the field generated by the original coil....

Would you then have a straight DC motor which could be reversed by altering polarity at the the armature and then speed controlled by using back emf methods?

Maybe I'm late to the party or just don't have sufficient understanding but have never heard such an alternative discuss.

Plausible. ..or non-value-added?
