The armature reaction of the hybrid excitation starter generator (HESG) under load conditions will affect the distribution of the main magnetic field and the output performance. However, using the conventional field-circuit combination method to study the armature reaction has the problem of low accuracy and inaccurate influencing factors. Therefore, this paper proposed a graphical method to analyze the armature reaction and a new type of HESG with a combined-pole permanent magnet (PM) rotor and claw-pole electromagnetic rotor. The analytical formula of the voltage regulation rate under the armature reaction was derived using the graphical method. The main influencing parameters of the armature reaction magnetic field (ARMF) were analyzed, and the overall output performance was analyzed using finite element software. On this basis, comparison analyses before and after optimization and the prototype test were carried out. The results show that the direct-axis armature reaction reactance, quadrature-axis armature reaction reactance, and voltage regulation rate of the optimized HESG were significantly reduced, the output voltage range of the whole machine was wide, and the voltage regulation performance was good.

The pursuit of innovative and sustainable engine technologies has led to the exploration of electromagnetic solenoid engines as a potential alternative to traditional internal combustion engines, specifically within the context of electric vehicles (EVs). This work aims to design, build, and test a prototype electromagnetic solenoid engine, leveraging the principles of electromagnetism to convert electrical energy into mechanical motion suitable for EV applications. The solenoid engine operates by using electric current to generate a magnetic field within solenoids, which in turn drives a piston to produce linear motion. Through detailed simulations and experimental prototypes, key performance metrics such as energy efficiency, power output, thermal management, and system durability are examined. Additionally, the study investigates the impact of various design parameters, including solenoid coil configuration, magnetic materials, and control strategies, on the overall performance of the engine. The findings demonstrate the feasibility of using electromagnetic solenoids for electric vehicle propulsion, highlighting potential benefits in terms of reduced emissions, lower noise levels, and enhanced efficiency. This research contributes to the advancement of green propulsion technologies, providing valuable insights for the development of next-generation sustainable engines for electric vehicles.

Permanent magnet-assisted synchronous reluctance motors (PMSRMs) have been widely used in household appliances, national defense and the military, due to their advantages of low cost and high efficiency. However, their excessive torque ripple cause a series of problems, such as high vibration and noise. To solve this problem, this paper first considers the important factor that causes the torque ripple—the cogging torque. Firstly, the generating principle of the cogging torque is analyzed, and a method combining magnetic pole migration and the stator auxiliary groove is proposed. On this basis, considering the position, width, depth, quantity and shape of the auxiliary groove, the Taguchi method is used to optimize the proposed improved structure. Finally, a new motor structure that can minimize torque ripple is obtained. Compared with the original structure, the cogging torque is reduced by 57.6%, the torque ripple is reduced by 38%, and the electromagnetic torque is only reduced by 1.6%.
