Abstract
Some embodiments include a system, comprising: an enclosure configured to enclose a vacuum; a cathode disposed within the enclosure; an anode disposed within the enclosure configured to receive a beam of electrons from the cathode; a motor disposed within the enclosure and configured to rotate the anode in response to a drive input; and a circuit electrically connected to the drive input, and configured to generate a phase signal based on a voltage of the drive input and a current of the drive input, the phase signal indicating a phase difference between the voltage of the drive input and the current of the drive input.

A system, comprising:
- an enclosure configured to enclose a vacuum;
- a cathode disposed within the enclosure;
- an anode disposed within the enclosure configured to receive a beam of electrons from the cathode;
- a motor disposed within the enclosure and configured to rotate the anode in response to a drive input;
- and
- a circuit electrically connected to the drive input, and configured to generate a phase signal based on a voltage of the drive input and a current of the drive input, the phase signal indicating a phase difference between the voltage of the drive input and the current of the drive input.
A system, comprising:
- an enclosure configured to enclose a vacuum;
- a cathode disposed within the enclosure;
- an anode disposed within the enclosure configured to receive a beam of electrons from the cathode;
- a motor disposed within the enclosure and configured to rotate and receive a drive input;
- a sensor and configured to receive a signal from the motor;
- and
- a circuit electrically connected to the sensor, and configured to generate an indication of a status of the motor in response to the signal received from the motor.
A system, comprising:
- means for operating a motor within an enclosure of an x-ray tube enclosing a vacuum;
- means for measuring a phase shift between a voltage and a current driving a motor during operation;
- and
- means for generating an indication of a status of the motor in response to the phase shift.
