Kind Code:
B2
Abstract:
PCT No. PCT/CH96/00335 Sec. 371 Date May 6, 1998 Sec. 102(e) Date May 6, 1998 PCT Filed Sep. 26, 1996 PCT Pub. No. WO98/11650 PCT Pub. Date Mar. 19, 1998The rotary pump (3) according to the invention comprises a housing (9) and a rotor (2) with blades (1b) located inside the housing (9), with the rotor (2) comprising a passive, magnetically effective rotor part (1) and the housing (9) being surrounded by a stator (7) that has electrical windings (8a, 8b, 8c, 8d, 8e, 8f, 8g, 8h) and teeth (7a, 7b, 7c, 7d, 7e, 7f, 7g, and 7h), with the stator (7) and the rotor part (1) forming a bearingless motor, and with the rotor part (1) being actively controllable and drivable by means of the electrical windings (8a, 8b, 8c, 8d, 8e, 8f, 8g, 8h) relative to three degrees of freedom, and with the rotor part (1) and the teeth (7a, 7b, 7c, 7d, 7e, 7f, 7g, and 7h) of the stator (7) being designed to be geometrically adapted to one another and arranged with respect to one another in such fashion that the rotor part (1) can be held by passively acting reluctance forces in the stator (7) with respect to three additional non-actively-controllable degrees of freedom, in order to locate the rotor (2) inside the housing (9) in a drivable and floating fashion with zero contact.
