Abstract

The invention relates to a pump (1) comprising a motor (2), a drive shaft (3) and an impeller connected to the drive shaft (3), said motor (2) comprising a stator (4) and a rotor (6) of hybrid type, wherein the hybrid rotor (6) comprises a rotor core comprising an annular radially outer section of asynchronous type and an annular radially inner section of synchronous type, wherein the inner section comprises a number of permanent magnets. The hybrid rotor comprises two poles, wherein the total permanent magnet area per pole is in the range 500 to 600 square millimeters, and the total rotor slot area per pole is in the range 400 to 600 square millimeters, or four poles, wherein the total permanent magnet area per pole is in the range 200 to 350 square millimeters, and the total rotor slot area per pole is in the range 100 to 300 square millimeters.
