  • Control of an Electric Machine Integrated With the Trans-Rotary Magnetic Gear in a Motor Drive Train
    IEEE Transactions on Industry Applications, 2017
    Co-Authors: Siavash Pakdelian, Morteza Moosavi, H. A. Hussain, Hamid A. Toliyat
    Abstract:

    This paper studies the dynamic performance of an Electric Machine integrated with the transrotary magnetic gear (MITROMAG) in a motoring mode of operation. MITROMAG is formed by mechanically coupling a rotary Electric Machine to the rotor of a trans-rotary magnetic gear (TROMAG). TROMAG is a magnetic device that, through magnetic fields, converts a low-torque, high-speed rotation of its rotor to a high-force, low-speed linear motion of its translator, and vice versa. In a motoring mode of operation, the rotor of the TROMAG is driven by a rotary Electric motor, and as a result, its translator drives a reciprocating load. A nonlinear dynamic model is developed for the TROMAG. Oscillation tests are presented as examples of how the model can be used to predict the dynamic behavior of the device. The model is then linearized to derive system transfer functions and study the dynamic response of the MITROMAG to speed commands. Experimental results confirm the analysis.

  • Design of an Electric Machine Integrated with Trans-Rotary Magnetic Gear
    IEEE Transactions on Energy Conversion, 2015
    Co-Authors: Yateendra B. Deshpande, Siavash Pakdelian, Hamid A. Toliyat
    Abstract:

    Design aspects of the trans-rotary magnetic gear (TROMAG) integrated rotary Machine are discussed in this paper, with particular focus on optimizing system cost and weight. Analytical models are used for design of the TROMAG. Optimal designs of the rotary Machine are found by using a population-based genetic algorithm and two-dimensional finite-element analysis and thermal considerations. Weight, volume, and cost of the resultant system are then compared with the Pareto-optimal set of a permanent magnet linear tubular Machine that is designed for the same force and speed specification. It is shown in this paper that, for high-force low-speed reciprocating motion applications, an electromechanical motion system consisting of a TROMAG and a rotary Electric Machine can far surpass a conventional direct drive linear Machine in terms of weight, volume, and initial and operating cost.

  • An Electric Machine integrated with trans-rotary magnetic gear
    2012 IEEE Energy Conversion Congress and Exposition ECCE 2012, 2012
    Co-Authors: Siavash Pakdelian, Yateendra Deshpande, Hamid A. Toliyat
    Abstract:

    This paper introduces a novel electromechanical energy conversion system, called Machine Integrated with Trans-Rotary Magnetic Gear (MITROMAG) as a force-dense linear motor/generator. The device is obtained by integrating a Trans-Rotary Magnetic Gear (TROMAG) into a 3-phase winding. The TROMAG converts a low speed high force linear motion of a translator to a low torque high speed rotation of a rotor. Upon adding Permanent Magnet (PM) poles to the outer surface of the rotor of the TROMAG, it also serves as the rotor of an inner rotor PM Machine. The resultant electromechanical device is compared to a PM linear tubular Machine, as a benchmark, for a given force and speed. Simplified analytical models along with accurate field solutions and Finite Element Analysis (FEA) are employed to design the systems. It is shown that, for the given design specifications, the MITROMAG would surpass the linear PM Machine in regard to the volume and weight with a great margin.

  • torque characteristics analysis of an eddy current Electric Machine for automotive braking applications
    American Control Conference, 2006
    Co-Authors: R. C. Stevenson, S. Anwar
    Abstract:

    We introduce an enhanced parametric model for a copper-layered eddy current Electric Machine (retarder) for automotive braking applications. The modeled torque characteristics of the copper-layered electromagnetic retarders are based on the results from a detailed electromagnetic finite element analysis (FEA) of these eddy current Machines. The model uses a parameterized double-exponential function to model the steady state speed-torque characteristics of the retarder. The parameters are adjusted for optimal braking performance in conjunction with predicted speed-torque characteristics of a copper-layered retarder. A full vehicle model, along with the proposed retarder speed-torque model has been used to simulate a series braking events. The simulation results show that the peaks of the retarder speed-torque curves must be designed to occur within a specific range of speeds for optimal braking performance.
