Focusing on the unstable electromagnetic performance of an air gap magnetic field caused by torque ripple and harmonic interference a multi-slot multi-pole low-speed high-torque permanent magnet synchronous motor (LHPMSM), asymmetric stator slot is proposed to improve comprehensive motor. Moreover, this paper develops exact analytical model which predicts distribution based Laplace’s Poisson’s ...

The transition to electric vehicles (EVs) has received global support as initiatives and legislation are introduced in of a zero-emissions future envisaged for transportation. Integrated on-board battery chargers (OBCs), which exploit the EV drivetrain elements into charging process, considered an elegant solution achieve this widespread adoption EVs. Surface-mounted permanent-magnet (SPM) mach...

2-time slot cooperative relay can be used to increase the cell-edge throughput. Adaptive data modulation further improves the throughput. In this paper, we introduce adaptive modulation to singlecarrier (SC) cooperative decode-and-forward (DF) relay. The best modulation combination for mobile-terminal (MT)-relay station (RS) and RS-base station (BS) links is determined for the given local avera...

A new Single-sided Variable Flux Permanent Magnet Linear Machine with flux bridge in mover core is proposed this paper. The prevents the leakage from and converts it into linkage, which greatly influences performance of machine. First, a lumped parameter model used to find suitable coil combination no-load linkage machine, reduces computational time drive storage. Secondly, machine replaces exp...

Aiming at the shortcomings of complex mechanical transmission structure and low efficiency existing belt conveyor driven by asynchronous motor, this paper focuses on investigation a new type low-speed high-torque-density direct-drive permanent magnet synchronous motor (LHDPMSM) for driving conveyor. The proposed LHDPMSM utilizes external rotor to achieve goal fully direct drive First, topology ...

nowadays the use of the switched reluctance motors (srms) has been considerably increased in various home and industrial applications. despite of many advantages of this type of motors, such as simple structure, low cost, and high reliability, the main disadvantage of them is the generation of high torque pulsation. this paper presents a novel method to optimize a typical srm such that the torq...

This paper analyzes and compares models for predicting average magnet losses in interior permanent-magnet motors with fractional-slot concentrated windings due to harmonics in the armature reaction (assuming sinusoidal phase currents). Particularly, loss models adopting different formulations and solutions to the Helmholtz equation to solve for the eddy currents are compared to a simpler model ...
