In this paper, Switched Reluctance Motor (SRM) to be employed electric vehicle (EV) is designed using finite element method (FEM). The static torque of SRM is estimated with the magnetic field analysis. The temperature rise with time of SRM is estimated with the heat transfer analysis. First, the static torque and temperature rise with time of 600W SRM included in an experiment set, and are compared with the calculated results using FEM under the same conditions. The validity of magnetic field analysis and heat transfer analysis is verified by the comparisons. Also, the 60 [kW] SRM employed in EV, whose output characteristics are equal to 1500 [cc] gasoline engine, is designed with the magnetic field analysis and heat transfer analysis. 1-IntroductionThe problem depletion of the petroleum depletion, the serious environmental problem of global warming by C02 and air pollution by NOx are caused by the rapid development of the car society. As a solution for these problems, the following gradually spread: High mileage automobiles and low emissions vehicle such as in hybrid vehicle (HV). However, the penetration ratio of HV stagnates, and it is hard to be called a winning hit which solves the problem. This is because the price of HV is still higher than the price of gasoline-powered vehicle (GV) of equal power.Switched reluctance motor (SRM) rotates due to reluctance torque which originates from the change of the resistance of the magnetic circuit. The stator and rotor have salient pole structure, made from laminated nonoriented electrical steel. The concentrated winding coils are installed only in the stator. The SRM is known by its low cost. The structure is simpler than induction motor and synchronous motor. Since its rotor has winding coils or permanent magnets. Therefore, SRM has the possibility of standing high-speed rotations and operations at high temperatures under inferior road surface condition always recieving impacts and vibration, [1].The main problems present in the SRM are high torque pulsation and noise. However, those problems are being solved by development of the power electronics and improvement in the technology [2]. The improvement of basic performance for the SRM drive contributes to the extension of the application field, and the application of SRM to the electric vehicle (EV) begins to be examined recently. In the institutes, the following have already been done: Reports on the design of SRM for EV and reports on performance enhancement of the control method for SRM assuming the application to EV.Authors are tackling a project to employ a SRM in EV with power performance equivalent to a 1500 [cc] GV. In the project, a low cost SRM with solid features is chosen, and a design suitable for the dimensions and power of EV is done. The following goals as design guidelines are raised: Equivalent output characteristics with 1500cc gasoline engine, and making smaller and lighter. And, FF (the front engine front-wheel drive system) is adopted. Then, 2 SRMs of machines are used in order to omit the diff...

Our results suggest that even in the absence of 'no ink on tumor', the cancer size and grade in lumpectomy specimens are high-risk factors for residual disease, and this subgroup of patients may benefit from re-excision. Long-term follow-up of this cohort is required to determine their risk of recurrence after adjuvant treatment.
