Abstract
Systems are provided for a transformer of an electric machine. In one example, an externally excited electric machine includes a non-contact sensor that is mounted on a stationary ferromagnetic core of a transformer and a solenoid coil coupled to a rotating ferromagnetic core of the transformer. The sensor is a stationary sensor.
Claims20
An externally excited electric machine, comprising:
- a non-contact sensor mounted on a stationary ferromagnetic core of a transformer;
- and
- a solenoid coil coupled to a rotating ferromagnetic core of the transformer.
A transformer of an externally excited electric machine, comprising:
- a first yoke configured to rotate about an axis;
- a second yoke spaced away from the first yoke, wherein the second yoke is stationary;
- a solenoid coil coupled to the first yoke;
- and
- a Hall-effect current sensor coupled to the second yoke.
2 more elements
An externally excited electric machine, comprising:
- a sensor mounted on a stationary ferromagnetic core of a transformer;
- and
- a solenoid coil coupled to a rotating ferromagnetic core of the transformer, wherein the solenoid coil and the sensor face a gap between the stationary ferromagnetic core and the rotating ferromagnetic core.
