Abstract This paper focuses on the study of an ultra-micro permanent magnet stepper motor with automatic adjustment of interpupillary distance for VR helmets. To precisely adjust the rotation of the motor, the control requirements for the motor are very important, which also makes the time constant of the micro permanent magnet stepper motor of great significance. Starting from the voltage, torque balance equations and thermal balance equations, the paper analyzes and compares the electrical time constant, mechanical time constant, electromechanical time constant and thermal time constant of t

Abstract:
Permanent magnet synchronous generators (PMSG) converts mechanical energy into electrical energy through electromagnetic induction, with the excitation field generated by permanent magnets instead of coils. This paper investigates the effects of varying magnet thickness and width on the back electromotive force (back EMF) of an 18-slot 16-pole PMSG using finite element method (FEM) simulations. The aim is to understand how these geometric parameters influence the back EMF values, which are crucial for generator design and performance evaluation.

Abstract:
Traditional diesel generators on a merchant ship, composed of a wound rotor synchronous generator and a four-stroke diesel engine, supply electrical power for various loads. Recently, shaft generators for merchant ships have been increasingly replacing diesel generators to reduce CO2 emissions through fuel efficiency improvement. In particular, permanent magnet synchronous generators have replaced induction generators due to their high-efficiency characteristics at light loads. The surface-mounted permanent magnet rotor can be a suitable topology owing to the relatively short constant power ra

On the other hand, renewable alternatives are not always of constant speed, and are usually not high enough to turn conventional alternators.

Abstract:
A novel augmented railgun using a permanent magnet is proposed in this paper. The effects of the permanent magnet on the magnetic field and distribution of current density have been investigated. High current densities in the railguns can lead to high local temperature and erosion of the rails. Therefore, the current densities in the rails and armature should be decreased without the reduction of the Lorentz force which is required for acceleration. For this purpose, augmentation of the magnetic field can be used as an effective method. The Finite Element Method (FEM) simulations have been app

Abstract:
Given their 2.2 μs lifetime, muons must be accelerated fairly rapidly for a neutrino factory or muon collider. Muon bunches tend to be large. Progress in fixed field, alternating gradient (FFAG) lattices to meet these challenges are reviewed. FFAG magnets are naturally wide; low momentum muons move from the low field side of a gradient magnet to the high field side as they gain energy. This can be exploited to do double duty and allow a large beam admittance without unduly increasing the magnetic field volume. If the amount of RF must be reduced to optimize cost, an FFAG ring can accommodate e

Abstract:
The objectives of this project were to develop nondestructive methods for detection of internal properties and firmness of fruits and vegetables. One method was based on a soft piezoelectric film transducer developed in the Technion, for analysis of fruit response to low-energy excitation. The second method was a dot-matrix piezoelectric transducer of North Carolina State University, developed for contact-pressure analysis of fruit during impact. Two research teams, one in Israel and the other in North Carolina, coordinated their research effort according to the specific objectives of the proj
