The high‐temperature electric‐actuated valve widely adopts the split structure, and the valve stem drives the opening and closing of the valve after passing through the high‐temperature packing and sealing structure. However, the transmission chain is too long, which cannot meet the pursuit of small volume and lightweight in the nuclear industry. In this paper, a novel integrated structure of high‐temperature direct drive electric‐actuated valve canned permanent magnet synchronous motor (DDEAV‐CPMSM) is proposed. The structure omits the dynamic sealing structure composed of stuffing box, pressure plate and pressure sleeve, as well as the transmission structure of gears and couplings, and the reliability is significantly improved. This paper focuses on the calculation of the dimension parameters, thermal load design, and electromagnetic vibration of DDEAV‐CPMSM, and compares it with the integrated structure of the induction motor to explore the optimal topology of the high‐temperature electric‐actuated valve. Aiming at the problem of serious heat generation in limited space, it is difficult to simulate the running time of high‐temperature valve. Based on the magneto‐thermal coupling method, a 3D temperature field model considering high‐temperature heat source, canned sleeve eddy current loss, and hydraulic friction loss is established. The steady‐state temperature distribution of the system at high temperature and the transient temperature change law of valve opening and closing are analyzed, and the minimum time of secondary start‐up and the maximum running time under fault conditions are further studied, to provide a theoretical basis for the application of DDEAV‐CPMSM. © 2022 Institute of Electrical Engineers of Japan.

“…The thermal analyses is done with a stand-alone simulation tool [8,9] for SRM developed in MATLAB/SIMULINK with the improved lumped thermal network method for transient working conditions (detailed description in [10]) with the material properties for an ambient temperature of 20°C and the additional thermal parameters shown in Table II . [11,12] The thermal lumped parameter network design is based on the hypothesis that the machine structure, under the thermal point of view, can be divided into several parts having the same behavior and connected one to the other by the means of thermal resistors and capacitors.…”

The purpose of this paper is the design of different switched reluctance drives for an existing drive train of an electromechanical actuation system of a small unmanned aerial vehicle. Therefore, the outside dimensions of the switched reluctance machine are determined by the used permanent magnet synchronous motor size to allow the easy exchange of the motor drives. Moreover, the switched reluctance machines should fulfill the same control requirements as the reference motor.

A canned electrical machine is featured by having a can shield in air gap as partition. Considerable ohmic loss generated from the can (can loss) is the most highlighted feature. In this paper, an analytical electromagnetic model is proposed to analyze can loss. The model is divided into calculation of magnetic vector potential and modeling of magnetic saturation. In particular, the loss influenced by salient poles is discussed. The studied canned machine is a 3‐phase 12/8 switched reluctance machine as a pump drive. It is stressed that we do not judge and discuss performance of the machine developed but propose a modeling approach to improve the loss calculation approach. The developed method has been validated with simulation and experiments. The model gives accurate calculation of losses for electrical machines of high magnetic saturation effect.
