Aiming at the difficulty of measurement of permanent magnet rotor temperature, a wireless temperature monitoring scheme is designed based on wireless power and signal transmission. The rotor temperature monitoring position is determined by finite element analysis of rotor temperature field. Based on the principle of magnetic coupling resonance, a wireless power supply circuit is designed. A wireless power supply circuit and a wireless temperature monitoring circuit are designed based on ARM chip, and through the USB serial port and PC-side communication, the temperature data are transferred to the host computer software to achieve real-time temperature monitoring. Finally, the validity of the design is verified by experiments. [ABSTRACT FROM AUTHOR]

The teaching of special electrical machine is a continuation of the normal machine. The construction and magnetic field distribution of special electrical machine are different from those of the normal electrical machine , the concepts of all kinds of fields are very abstract. In order to increase the learning interest of the students and make the learning content of motor more intuitive, we take the linear machine as an example, do modeling and simulation by-Maxwell 3D. The material properties of motor parts are defined in the simulation, and subdivision of stator and dynamic settings are completed, boundary condition is load, solving and post-processing are then carried out. This paper analyzes the magnetic field and electric current density, provides visual display of magnetic field distribution and information of torque. To strengthen students’ understanding of the basic structure and working principle of linear motor, we change the abstract concept of magnetic and electric fields into visualization, cultivate the students’ imagination and creativity. The presented method has reference value for the teaching process of other special electrical machine, and builds the foundation for virtual experiment and further researches of motors.

Power grid interconnection technology based on the variable frequency transformer( VFT) is a research hotspot at present. The technique can solve the problems of a traditional back-to-back HVDC that has complex devices and being difficult to adjust power smoothly. The model of the VFT interconnecting two grids asynchronous is developed with Matlab / SIMULINK and the feasibility of interconnecting asynchronous grid and the case of the transmission power change are simulated. An experimental scheme based on VFT for asynchronous network interconnection is designed and an experimental platform is set up to verify the ability of interconnecting two asynchronous grids based on VFT in cases of normal operating,under frequency disturbance and power flow changing. The experimental design results accord with the theoretical analysis. [ABSTRACT FROM AUTHOR]
