Title:
電気機械のローターパラメータを測定するためのローター測定ユニットを備える電気機械
Document Type and Number:
Japanese Patent JP6900504
Kind Code:
B2
Abstract:
The present disclosure relates to an electrical machine (11) comprising: an exciter stator (13a), a stator (21), a rotor assembly (12) comprising a main machine rotor (19) having a field winding (19a), and an exciter rotor (13c) having an exciter rotor winding (13d), the exciter stator (13a) and the exciter rotor (13c) forming part of an AC/AC exciter (13), a multi-phase exciter rectifier (17) arranged on the rotor assembly (12), and configured to rectify an AC current from the exciter rotor winding (13d) to feed the field winding (19a) with a DC current, wherein the multi-phase exciter rectifier (17) has a plurality of phase legs, each phase leg being connected to a respective electrical phase of the exciter rotor winding, and a rotor measurement unit (1) mounted onto the rotor assembly (12) for measuring a rotor parameter, the rotor measurement unit (1) comprising: a measurement system configured to measure the rotor parameter, electronic circuitry configured to receive a rotor parameter measurement from the measurement system, and a first and a second power supply terminal connected to respective electrical phases of the exciter rotor winding or to the field winding to enable powering of the electronic circuitry during standstill operation of the electrical machine (11).
