Abstract

A wet-motor pump having the rotor and the bearings utilize the pumped liquid, whereas the dry stator chamber with the stator windings is separated from and sealed against the rotor chamber through a tube-shaped can. The ends of the winding wires extend freely outwards on one side of the stator stack of sheets such as through an opening in the motor housing to be connectable to electric connections of a connection box mounted on the motor housing. A power cable for supply of energy to the windings is inserted in the connection box. The ends of the windings are connected to winding terminals in the stator chamber. The winding terminals are connectable to contacts and a plug. The plug comprising a shaft surrounding and isolating the contact may be inserted through the opening in the housing and into the stator chamber. As a result, a pump is obtained whereby the electric connections between the ends of the windings and the connections in the connection box may be provided in a simple and quick manner.
