IPM Machine Drive Design and Tests for an Integrated Starter–Alternator Application

This paper presents a novel strategy to compute the high-frequency signal injection response of an electrical machine adopted in a sensorless electric drive. Thanks to the proposed strategy the self-sensing capability of the machine can be evaluated during the design process. A small-signal model of the machine in the d-q reference frame is derived and adopted to perform suitable finite-element (FE) simulation to compute the machine parameters at the injection frequency. The proposed procedure is validated by the comparison with other simulation strategies as well as with experimental results

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. Frequently it is required the computation of the electrical machine parameters which are necessary for the tuning of the drive control algorithm. This paper deals with a strategy to compute the high frequency signal injection response of a sensorless controlled electrical machine. It allows to determine the self-sensing capability of the machine directly during the design process. Such a capability can be defined in any given operating point, for example along the Maximum Torque Per Amps trajectory. Then, also the high frequency machine parameters can be computed.In addition, the strategy proposed here requires a very short computational time to get such a data. 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 tensor 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.In order to validate the proposed procedure, experimental results on different machine type are included in the paper. This allows to prove the reliability of the procedure as a valued tool for the characterization of the machine.

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.
