By Yosuke Suzuki, Kenji Nakamura, Osamu Ichinokura [View]
[Download]

Abstract: Switched reluctance (SR) motors have desirable features including simple construction, high reliability, and low cost. In the previous work, we proposed one calculation method for operational characteristics of a SR motor considering magnetic nonlinearity. In this paper, based on the proposed method, we design and analyze an outer-rotor type multipolar SR motor for application to an electric vehicle (EV).

Abstract: A new approach to switched reluctance motors (SRM) optimal design based on simple relations between mechanical, magnetic and electric variables obtained by using elementary physical consideration of SRM behavior is presented. The obtained results of the simplified SRM design are the subject to be compared with parameters and characteristics of realized SRM samples. Obtained correction coefficients are used as an important element in the proposed SRM design procedure. A sensorless SRD control for electric bicycle is presented. The control system is based on 8–bit Motorola MC68HC908MR32 microcontroller realizing the method of indirect measuring of flux linkage. The hardware realization of current regulator provides effective phase current limitation at low speeds. Its operation is taken into account in sensorless control algorithm.

   Electromagnetic And Motion Coupled Analysis For Switched Reluctance Motor Using A Nonlinear Magnetic Circuit Model
By Kenji Nakamura, Koshiro Kimura, Osamu Ichinokura [View]
[Download]

Abstract: This paper presents an electromagnetic and motion coupled transient analysis method for a switched reluctance (SR) motor. First, we prepare a reluctance network analysis model of a 6/4-pole SR motor considering both magnetic saturation and leakage fluxes. Next, the proposed model is combined with its drive circuit, and with motion-calculation blocks on SPICE which is one of the general purpose circuit simulators. Using the proposed method, we can calculate dynamic characteristics of a SR motor quickly and accuracy.

Abstract: The Switched Reluctance Machine is being widely spread among industrial and domestic applications, replacing other electrical machines. However its modelling and control present important difficulties, due to complex system nonlinearities. In this paper it is shown how the use of formal language technique can help in the modelling of a Switched Reluctance Machine, overcoming these difficulties. Experimental tests with a lab prototype are performed in order to obtain a realistic and automatic machine model.

   Implementation Of An On-Line Learning Speed Controller For A Switched Reluctance Machine
By Silviano Rafael, A. J. Pires, P. J. Costa Branco [View]
[Download]

Abstract: In the classical speed control of electrical machines it is usual to have linear PID controllers. This kind of controllers can present good results near a given operating point, where the machine may be considered as a linear system. However, the classical PID controller may have some limitations if it is planed to be used in a wide working region. In this case a good alternative can be the learning controllers using fuzzy logic and neural networks. In this paper it is presented and mainly discussed a neuro-fuzzy learning controller for speed regulation of an 8/6 Switched Reluctance Machine. Experimental results are presented and discussed showing how the controller can learn in real time the “good” rules. The results obtained with a classical PID controller are shown as a reference speed controller for the analysis.

[Download]

Abstract: In this paper an optimized design for a small-scale shifted transverse flux reluctance motor using the Genetic Algorithm is presented. The goal is to minimize the motor volume or in the other words to maximize the produced torque. This paper describes a procedure in order to achieve an optimal design. Finally, analysis of the designed motor using a finite element method is performed and the results are compared to the analytical method as well.

   Network Operating Characteristics Based On Imposed MMF Waveforms For Switched Reluctance Generators
By P. Lobato, A. J. Pires, J. A. Dente [View]

Abstract: With the propose of improving the dynamic performance of the Switched Reluctance Generator (SRG) one analyses its operation using magnetomotive force (MMF) waveforms imposed in the linear region of the magnetic characteristics. In this paper, based on the proposed location of the dwell angle in the phase inductance profile, supported by energetic criteria, the SRG network operating characteristics were analysed for two typical cases: feeding a passive (ohmic) load and connected to a power network (infinite busbar).

   Smooth Sensorless Torque Control Of A Cage Synchronous Reluctance Motor
By Ruediger Kusch, Dietrich Naunin [View]
[Download]

Abstract: Position sensorless and smooth torque control for a commercially available cage synchronous reluctance machine is presented. A transverse laminated rotor structure with squirrel cage is easy to manufacture, can either be fed with a voltage source inverter or can be connected to the line. The contributions of this paper are twofold. First a modified control structure for a squirrel cage sychronous reluctance motor is shown to achieve smooth torque production at low speed. The squirrel cage synchronous reluctance motor has been investigated in order to make the work applicable to an industry standard type of machine. Second, encoderless position estimation using high frequency carrier signal injection is shown. The estimation accuracy and dynamic properties at low speed have been investigated. Experimental results for robust position estimation of a 4kW synchronous reluctance machine are given.
