Abstract:

Induction motors with ring windings (IMRW) are designed for the processing of nuclear waste. The sta-tor winding coils are covered with ceramic insulation to allow for long-term operation in conditions of increased radiation. The stator coils are ring shaped, in order to reduce the bend angle. The stator has a specific design consisting of tooth tips located around the axis of rotation and tooth cores placed over the tooth tips in a spiral. The first IMRW prototype was manufactured by UrFU together with “Uralelectromash”. It was designed to the same diameters as an induction motor of a classic

Abstract:

Detecting motor bearing faults by stator currents is of great importance as it improves the adaptability of measurement means to different environments and reduces the number of sensors. Therefore, many studies have been conducted to investigate bearing faults by constructing motor models, most of which have used signal models to simulate the dynamics of the bearings. However, the signal model may be exposed to the issue that the nonlinearities in the bearing operation are neglected, thus oversimplifying the coupling effects between the electromagnetic and dynamics models.

Abstract:

This paper deals with a model to simulate the operating of an autonomous induction generator. The model used is a diphase one obtained by the application of the Park transform. This model permits, when adopting some simplifying hypothesis, to take account of the saturation effect. This is achieved using a variable inductance function of the magnetising current. The non linearity is then based on the approximation of the magnetising inductance with regards to the current. In our case, we use a polynomial function, of 12th degree to perform it. This approach is simple and very accurate. The deve

Abstract:

Abstract Multi-DOF actuators are used in bionics where their flexibility is limited by changing batteries or wired charging methods. In order to realize flexible power supplement and accurate attitude measurement, a multiple-inputs and single-output wireless power transmission (WPT) attitude measurement method is proposed. Traditional contact measurement methods have large friction resistance, and some non-contact measurement methods are complicated in structure or calculation. In order to solve the above problems, the receiving coil is installed inside the rotor. When the rotor rotates, the r

Abstract:

This paper proposes the development of a new mathematical model dedicated to the diagnostic of the partial Demagnetization Fault (DF) in Permanent Magnet Synchronous Motor (PMSM). To do this, an extension of the Modified Winding Function Approach (MWFA) is proposed to accurately take into account the air gap asymmetry caused by the Demagnetization Fault (DF) in the PMSM inductances calculation. The calculated inductances are then used in the magnetically coupled electrical circuit model to simulate the PMSM behavior in the different operating modes. Finally, a diagnostic method based on the st
