CANNED MOTOR PUMP AND METHOD FOR FILLING FILLING MEMBER INTO STATOR CHAMBER THEREOF

摘要

A canned motor pump, wherein a motor stator is housed in a stator chamber that is a space between a tubular stator can for housing a motor rotor and a tubular stator band disposed coaxially with the stator can. The stator chamber is closed by annular end plates at the cylindrical ends between the stator can and the stator band. The stator chamber is filled with a filler. The filler is produced from spherical inorganic material particles filled into the stator chamber and resin for causing the particles to stick to each other. Consequently, the heat release performance of the stator of the canned motor pump is improved.
