The commonly used DC coil wounded around the electromagnet winding skeleton, acts as the key electro‐magnetic conversion element, is formed by enameled wire with poor heat dissipation. The electric conductivity of the conductors will be greatly influenced by the high temperature generated from coil's internal heat, especially for long‐term work conditions. Thus, in order to calculate the DC coil's temperature accurately and effectively during the primary design process of the electromagnet, a novel temperature rise calculation method for the steady and transient is proposed in this paper. First, the geometric and resistance models of the enameled wire are established, according to the spatial arrangement and the resistance‐temperature characteristics. Secondly, the temperature rise of the electromagnet coil is calculated theoretically, based on the steady and transient heat dissipation equations. Thirdly, the Thermal‐Electric simulation model is established, which is used to simulate and analyze the temperature of the electromagnet coil changing with excitation voltage. Finally, a temperature rise test platform of the electromagnet coil is established, the steady and transient temperature rise under various conditions is measured. The temperature rise results of theoretical calculation, simulation and experiment show good agreement with each other. It gives significant guidelines to the design and optimization processes of such electromagnet DC coil. © 2023 Institute of Electrical Engineers of Japan. Published by Wiley Periodicals LLC.

“…The coil is supplied with a sustained current to generate a magnetic field that interacts with a magnetisable armature, causing it to move in a linear motion. However, despite the low force generation resulting in minimal-size applications, the coil must still be continually activated during actuation, which results in a dramatic temperature rise [14]. If a cooling-down system is introduced, the size of the actuator would significantly increase and sealing problems may arise.…”

Single-port laparoscopic surgery (SLS), which utilises one major incision, has become increasingly popular in the healthcare sector in recent years. However, this technique suffers from several problems particularly the inability of current SLS instruments to provide the optimum angulation that is required during SLS operations. In this paper, the development of a novel latching-type electromagnetic actuator is reported, which is aimed to enhance the function of SLS instruments. This new actuator is designed to be embedded at selected joints along SLS instruments to enable the surgeon to transform them from their straight and slender shape to an articulated posture. The developed electromagnetic actuator is comprised of electromagnetic coil elements, a solid magnetic shell, and a permanent magnet used to enhance the magnetic field interaction along the force generation path and also to provide the latching effect. In this investigation, electromagnetic finite element analyses were conducted to design and optimise the actuator’s electromagnetic circuit. In addition, the performance of the new actuator was numerically and experimentally determined when output magnetic forces and torques in excess of 9 N and 45 mNm, respectively together with an angulation of 30° were achieved under a short pulse of current supply to the magnetic circuit of the actuator.

“…Because each layer is being heated by the adjacent layers at different rates, the temperature profile is formed. This temperature model is based off the model found in McIntosh and Ellis' model [6] with minor changes and considerations needed to be done to incorporate it for this project's use, namely the lack of solenoid section will not be present in this design.…”
