ABSTRACT This paper deals with an integrated starter-alternator (ISA) drive which exhibits a high torque for the engine start, a wide constant-power speed range for the engine speedup, and a high-speed generator mode operation for electric energy generation. Peculiarities of this ISA drive are thus its flux-weakening capability and the possibility to large torque overload at low speed. The focus on the design, analysis, and test of an interior permanent-magnet motor and drive for a prototype of ISA is given in this paper. In details, this paper reports on the design of stator and rotor geometries, the results of finite-element computations, the description of control system, and the experimental results of prototype tests.

    ABSTRACT: Low weight and volume are the principal requirements for electric components in hybrid motorcycles, and the energy storage system (ESS) is the most important part that contributes to this issues. This paper deals with the choice of the best ESS and with the optimization of the hybrid power train in two-wheeled vehicles. A methodology of investigation is given in order to recognize all the data necessary to find the best technology and size for the ESS. The techniques adopted for the design of the electrical machine (EM) are also reported. Furthermore, simulations with finite elements (FE) and mathematical software, in order to predict the EM and the drive performances, are presented. Efficiency maps from FE simulations are also given. Different kind of ESSs are compared with the goal to choose the best solution balancing cost, volume and weight for a reference motorcycle. The whole power train has been practically realized and the new hybrid vehicle has been tested first in appositely test bench and also in a small private racetrack. The measured experimental results are presented.

    ABSTRACT: This paper deals the design and experiment of 100kW interior permanent magnet (IPM) machine for ship application. The presented machine is used in anti heeling pump system of ship which plays a role to stabilize against ship rolling. High efficiency, low vibration and compact size are very important to this application, so the IPM machine will be good solution to this end. In this study, the design of IPM machine for marine application is introduced. Performances and torque characteristics are computed by 2 dimensional (2D) finite element analysis (FEA). The design of magnetic circuit and computational results are validated by experimental results with a prototype machine.

    ABSTRACT: A challenge during the design process of an electrical machine is the characterization of the various parameters in a computational time as short as possible. To this purpose, the analysis strategies are manifold. In addition, it is more frequent to obtain parameters of the electrical machine that are necessary for the drive control. In this paper, a strategy to compute the high-frequency signal injection response of an electrical machine adopted in a sensorless electric drive is presented. It allows to determine the self-sensing capability of the machine directly during the design process. Such a capability is defined in any given operating points (for instance along the maximum torque per Amps trajectory). In addition, the computational time required to get such data is very short. After a magnetostatic field analysis, carried out so as to get the torque for a given current, the flux density distribution is stored and the differential reluctivity is evaluated in each element of the mesh. Then, a time-harmonic analysis is carried out in a linearized structure so as to compute the d-q parameters at the injection frequency. The proposed procedure is applied to different type of machines and validated by comparison with experimental results.
