Abstract:
In order to enhance the initial velocity and energy conversion efficiency of multi-stage synchronous induction coil launchers, the direction of coil energization for the drive coils is studied. There are typically two energization methods for multi-stage launching devices: (1) PP (Positive-Positive), where positive current is applied to all drive coils, and (2) PN (Positive-Negative), where currents in opposite directions are alternately applied to the drive coils. A finite element model of a four-stage coil launcher is established in ANSYS2022R2, and the acceleration effects of the armature u

Abstract:
This study presents a computational model of an electromagnetic cannon developed using the ATP/EMTP simulation tool and its graphical interface, ATPDraw. The system features a cylindrical metallic armature that traverses multiple stages of circular coils. Employing the Voltage Behind Reactance (VBR) methodology, each coil is modeled as a dynamic equivalent circuit comprising a resistance, an inductance, and an electromotive force source. The model parameters are dynamically updated at each simulation time step based on the armature’s motion. The coils are energized by pre-charged capacitors an

Abstract:
As the core of electric propulsion in drones, the motor has higher requirements for its reliability and fault tolerance. Accurate acquisition of rotor position information is a prerequisite for a motor-driven drone’s system to operate stably. Traditional search coils can provide fault tolerance for position detection, but they cannot detect rotor position in the full speed range (stationary to rated speed). In order to make the search coils provide rotor position in the full speed range, this study proposes to inject an ultrahigh frequency (UHF) signal (50–100 kHz) into the search coils. By op

This paper presents the new design of Hybrid Excitation Flux Switching Motor (HEFSM) using segmental rotor structure. HEFSMs are those that consist all the excitation flux sources at their stator with robust rotor structure. The rotor is designed as segmental due to the reason that segmental rotor has ability to yield the magnetic path for conveying the field flux to nearby stator armature coil with respect to the rotation of the rotor. This design gives the clear advantage of shorter end winding compared to the toothed rotor as there is no overlap winding between field excitation coil (FEC) a

Similar to armature back electromotive force (armature back-EMF), the back-EMF also exists in the field winding of hybrid excited machines. However, the existence of field back electromotive force (field back-EMF) is harmful to the safe and stable operation of machine systems, e.g., higher losses, lower efficiency, higher torque ripple, and reduced control performance. This paper systematically investigates the influence of armature/field winding configurations together with stator/rotor pole combinations on the field back-EMF ripple in hybrid excited machines with switched-flux stators.

Abstract A quantity frequently needed by designers is the total electromagnetic force (or torque) on an object (e.g. an actuator armature or machine stator /rotor). Less frequently there may be a need for the force distribution acting on a coil or surface so that stresses on a component or the electromagnetically induced vibrational and acoustic behaviour of a device may be evaluated. Calculation of electromagnetic forces and particularly force distributions raises serious philosophical arguments as discussed, for example, by Carpenter (1959) and Carter (1962).
