“…Optical encoders, hall sensors, and resolvers are widely used in motors. Encoder and resolver provide acceptable angular position information, and recent studies have shown that hall sensors can also provide each location [8][9][10][11][12][13][14][15][16][17]. However, the addition of position sensors has disadvantages such as rising costs and increasing the volume of the system.…”

Conventional position sensors for permanent magnet synchronous motor, such as optical encoder, resolver, or hall sensor, can get fault by the stress. The fault of the motor position sensor may cause serious accidents. Thus, to prevent damages by the position sensor failure, adding a redundancy sensor such as wound search coil is recommendable. In this paper, a new planar search coil design that can be used as a position sensor for permanent magnet synchronous motor is proposed. This new design is a planar coil based on a flexible-printed circuit board that converts airgap flux to a back-electromotive force signal. Unlike the wound search coil design, the proposed design is advantageous for manufacturing and slot-space preservation. Also, this new design is distant from the motor main winding. As a result, the exposure of the electrical and thermal stresses to the sensing coil can be decreased. This research shows the mathematical model for the design of the new planar-shaped airgap flux search coil design. In addition, the position estimation algorithm based on the new search coil design is shown. Finally, the position estimation using the new search coil design is presented.

“…They concluded that the sinusoidal current drive could effectively decrease the eddy current loss and the temperature increase of the rotor [9]. Chen et al proposed a high‐precision position estimation method based on Hall vector frequency tracking of the high‐speed PMSM with bipolar Hall‐effect sensors [10, 11]. The proposed method provides a means to achieve high‐precision position estimation with low‐cost sensors.…”

Permanent magnet synchronous motor (PMSM) is the ideal drive for the magnetically suspended turbo-molecular pump (MSTMP) for its high power density, reliable operation and high energy efficiency. Rotor position information is necessary to drive the PMSM. However, because of the installation space limitation and reliability requirement, position sensorless control technology without mechanical position sensors is more attractive. In this study, a sliding mode observer is adopted to estimate the back electromotive force (EMF) that contains the position information. Since the high-order harmonics in the back EMF would lead to harmonic position errors, a fixed frequency extraction filter is proposed to filter out the harmonics. A high precision speed control is of importance to ensure the performance of the MSTMP and also contributes to achieving a better position estimation accuracy, especially under strong disturbances. Therefore, a composite speed controller combining a sliding mode speed controller and a sliding mode disturbance observer is proposed to improve the speed control performance of the MSTMP. The effectiveness of the proposed high-performance control method for the MSTMP motor is evaluated with experiments.

“…Among some of the newer technologies, Hall Effect sensors use a moving permanent magnet to create induction (electric current), sensed by the device. This eliminates the contact problems of mechanical limit switches, but they are susceptible to high magnetic fields [5]- [7]. Optical sensors use a light emitter to generate light and a light receiver to detect the presence of an object without physical contact [8].…”

The paper puts in perspective the aspects of classic valve construction and the use of off-the-shelf products in order to improve the valve's features in terms of user interface, valve status in operating conditions and control interface to classic standardized communication protocols, such as EtherCAT®, ProfiBUS®. Because the resulting products are meant to be functional prototypes, most parts used for implementing new features will not be fully developed as for a sellable product, but only to the stage of proof-of-concept. To fully develop the used equipment will imply a dedicated study, which would allow the shift from general purpose use development boards and breakout sensor boards to application-specific equipment designed for assembly line manufacturing. The same study includes the use of Internet-of-Things in industrial environment and will be the subject of separate and dedicated article. The paper only mentions the possibilities and ways of achieving future design ideas.
