“…Especially in high-speed motors, the skin effect of the stator winding will be more prominent under the action of high frequency, making the AC resistance of the stator winding much higher than the DC resistance. This phenomenon is generally suppressed by using a smaller conductor diameter in high-speed motors, which can effectively reduce the loss of the stator winding [20][21] . In the paper, only 0.67mm conductor diameter is selected, so the influence of skin effect can be ignored in calculation.…”

The operating temperature of the motor is directly influenced by motor loss, and there is a significant difference in the distribution of loss between high-speed motor and conventional speed motor, so it is extremely important to analyze the temperature field of high-speed motor. The manuscript takes a highspeed induction motor as an example for three-dimensional temperature field analysis, calculates the temperature field of the motor under various loss conditions, and obtains the characteristic relationship between different loss and winding temperature and rotor squirrel cage temperature. The rationality of the simulation model and the correctness of the analysis results are verified by comparing the motor's full load operation test with the simulation results. Finally, the basic design ideas for high-speed motors are summarized.

“…After years of development and precipitation, the electrical engineering discipline has a well-established system for training students who are well versed in the theoretical foundations of the electrical The current introduction of IoT technology in university education has a large deficiency, such as the lack of the most basic introduction to fundamental chip application and the technical principles of the IoT [80]. Various automated devices in the Energy Internet, such as robots and wearable detection devices, are built based on these technologies; thus, students are not educated to address and deal with the technical means of IoT applications in the Energy Internet, such as home energy management, smart street light management, and coordination of source networks and loads, which will greatly reduce the efficiency of the Energy Internet [81].…”

After the concept of the Energy Internet was proposed in the last century, it has become a topic of great interest in recent years with the development of related technologies and the growing environmental problems. At the same time, the new technology brought by it also poses new challenges for the electrical engineering specialty, which is inseparable from power plants, power grids and other power facilities. How to reform the electrical engineering specialty to better meet the challenges it brings has become a problem that cannot be ignored. This paper comprehensively analyzes the current development status of the Energy Internet, key technologies involved in the concept of the Energy Internet, and problems in current talent training. This paper proposes to carry out curriculum reform through two main lines and to further optimize the curriculum structure, thus forming a more reasonable training program.

“…For the solid rotor bars, it was shown that magnetic bridging of semi/closed rotor slot structure, which is a common design for inverter‐fed cage IM, reduces the skin effect [26]. The finite element analysis (FEA) in [27] depicts that the skin effect of rotor bars increases by magnetic saturation and skewing. For 5.5 kW IM with semi‐closed rotor slot, the current density at the top rotor bar is about 15 times its value at the middle and bottom bar area.…”

This paper revisits loss model control (LMC) of the 3‐phase induction motor (IM) and presents a robust LMC algorithm for medium‐sized pump drives. Compared with other power loss reduction algorithms for IM, the presented one has the advantages of fast and smooth flux adaptation, high accuracy, and versatile implementation. An improved loss‐model for IM drive has been developed. The model considers the surplus power loss caused by inverter voltage harmonics and magnetic saturation using closed‐form equations. Further, the resistance‐temperature change is considered by a first‐order thermal model. To determine the optimal flux level that achieves maximum drive efficiency, an artificial neural network (ANN) controller is synthesised and trained offline. The voltage and speed control loops are connecting via the stator frequency to avoid the possibility of excessive magnetization. Beside, the obtained thermal information enhances motor protection and control. These together have the potential of making the proposed algorithm robust and reliable. The system reliability is investigated and assessed in terms of energy saving using ramp start/stop. Theoretical analysis, computer simulations, and experimental studies are performed on 5.5 kW variable speed water pump using the proposed control. The test results are provided and discussed to validate the effectiveness.
