A system and method for controlling bending modes of a rotor assembly is disclosed. The rotor assembly can be supported by one or more bearings in an integrated machine. The method can include accelerating the rotor assembly to a first rotational speed via a first torsional force applied to the drive shaft and then removing the first torsional force. The method can also include obtaining first measurements of the rotational speed and frequency of one or more bending modes of the rotor assembly during a first rotary machine coast down period from the first rotational speed. The process can be repeated to determine a relationship between rotational speed, bending mode frequency, and gain. The one or more bearings can then be controlled based on the measurements and the relationship. The system can have one or more processors or controllers to implement the method.

System and method for measuring bending mode frequencies

A power connector for an electric motor is disclosed. The power connector includes a flange, a conductor rod, and an insulation sleeve. The conductor rod includes a first portion extending in a first direction from the flange and a second portion extending from the flange in a second direction, opposite the first direction. The second portion includes a lead wire connection end distal to the flange. The insulation sleeve covers the second portion from the flange to the lead wire connection end. The insulation sleeve includes a sleeve outer surface, and a sealing rib extending outward from the sleeve outer surface.

Penetrator power connector for an integrated rotary machine

A method for controlling a gas compressor is disclosed. The method includes communicating feedback data about two magnetic bearings to a computer including a multi-core processor via a communication link. The method also includes processing the feedback data about the two magnetic bearings where the feedback data for each of the two magnetic bearings is processed on separate cores of the multi-core processor in parallel and issuing a bearing control command to each of the two magnetic bearings in response to the feedback data. The method further includes communicating the bearing control commands to the two magnetic bearings from the computer via the communication link.
