The calculation of can losses in canned motors

CANNED MOTORS are those which are distinguished by having a thin cylindrical metal diaphragm or “can” in the inner bore of the stator, thus serving to isolate the stator windings from the fluid which completely fills the rotor cavity. These motors are generally of the squirrel-cage induction type and their rotors are also normally canned in order to prevent corrosion of the bars, end rings, and punchings from the fluid in the air gap.
