Fluid pump, particularly external gear pump, has rotating pump elements, housing and electromotive drive, which rotates pump elements, where one of pump elements forms rotor of electromotive drive

摘要

The fluid pump has two rotating pump elements (16), a housing (12) and an electromotive drive, which rotates the pump elements. One of the pump elements forms a rotor (17) of the electromotive drive. The pump element comprises a ferromagnetic material (36) and two windings (24) belonging to a stator (28) of the electromotive drive are arranged radially or axially outside the pump element. An independent claim is also included for a controlling- or regulating device for operating a fluid pump.
