  • Publication number: 20250163924
    Abstract: A turbomolecular vacuum pump includes a stator, a rotor to rotate inside the stator, and a motor to drive the rotation of the rotor. The turbomolecular vacuum pump further includes a temperature sensor to measure the temperature of the rotor and a creep maintenance meter to determine an incremental change in the creep of the rotor over a predetermined duration from the temperature of the rotor, as measured by the temperature sensor, from the rotational speed of the rotor, from the value of the creep of the rotor, and from the look-up table, to increment the rotor-creep value by the determined creep increment, and to determine, based on the incremented creep value, a data item indicative of the remaining time for which the rotor can run before needing preventive maintenance for creep.

  • Patent number: 9564792
    Abstract: The invention relates to an electric motor having a rotor and a coiled stator, the rotor including a shaft and two disks that are rotatably fixed to the shaft and provided with permanent magnets, an outer portion of the stator extending from each disk axially parallel to a rotational axis of the rotor and radially beyond same, from the axis. The stator includes a plurality of disjointed bars made of a magnetically conductive material, certain parts of which form the outer portion of the stator. The stator also has a carrier structure holding the bars such that they are fixed in relation to each other, the carrier structure being mounted in such a way that it can rotate on the shaft, axially outside the two disks. The outer portion of the stator extends parallel to the rotational axis, axially outside the disks of the rotor, up to the carrier structure.
