FLÜSSIGKEITSPUMPE MIT MAGNETISCH AUFGEHÄNGTEM LAUFRAD |
摘要 |
A pump portion (20) is provided with an impeller (23) internal to a casing (21). The impeller (23) is coupled with a rotor (12) physically out of contact therewith and it is also supported by a controlled, magnetic bearing portion (111) physically out of contact therewith. The impeller (23) is rotated by a motor (13) to discharge fluid. A position sensor (62) detects the impeller (23) position in levitation and in response to the sensor's output the magnetic bearing portion (111) is controlled. The magnetic bearing portion is configured of a plurality of electromagnets formed of a magnetic pole (51-56), a yoke (71-76) and a coil (81-86). The electromagnet has magnetic S and N poles each with at least yoke and coil arranged circumferentially. <IMAGE> |
