A novel integrated structure with a radial displacement sensor and a permanent magnet biased radial magnetic bearing.

Sun J, Zhang Y - Sensors (Basel) (2014)

Bottom Line: In this paper, a novel integrated structure is proposed in order to reduce the axial length of the high speed of a magnetically suspended motor (HSMSM) to ensure the maximum speed, which combines radial displacement sensor probes and the permanent magnet biased radial magnetic bearing in HSMSM.The sensor probes are integrated in the magnetic bearing, and the sensor preamplifiers are placed in the control system of the HSMSM, separate from the sensor probes.The proposed integrated structure can save space in HSMSMs, improve the working frequency, reduce the influence of temperature on the sensor circuit, and improve the stability of HSMSMs.

f15-sensors-14-01950: The relationship between temperature and coil current.

Mentions: The relationship between the temperature of the sensor probe and the coil current of a channel is shown in the online experiment in Figures 15, 16 and 17 where the temperature of the sensor probe is at 37 °C and 98 °C, respectively. In these figures, 1 V denotes 0.15 A. To be sure, the sensor circuit is separated from sensor probes, so the temperature of the sensor circuit is from 20 °C to 70 °C, while the temperature of the sensor probes is from 37 °C and 98 °C.
