http://en.wikipedia.org/wiki/Resolver_(electrical)

Resolvers tend to be very rugged and are used in environmentally difficult situations.

Encoders generally have better resolution but are not as mechanically robust. (Absolute) encoders can report position without homing which resolvers cannot do.
