Split sleeve motor pump with a permanent-magnet excited synchronous motor

摘要

The object of the invention is a split sleeve motor pump with a permanent magnet synchronous motor, the stator and rotor by means of a separate the cracking tubes 10 with respect to the fluid pumped encapsulated and the permanent magnets are arranged paraxially, wherein the north - and south poles of the permanent magnet over the circumference are alternately oriented toward the outside.The use of a conventional frequency converter for feeding of the motor of such a split sleeve motor pump and the thereby achieved, in separate process steps, which is designated as to be used in advantages is achieved in that the rotor - and the stator packet, in each case with the cracking tubes 10 made of electrically conductive material are encapsulated.
