“…Absence of permanent magnets, robust structure and phase independent operation makes SR motor competitive to PM brushless motor. The design of SR motor having torque, power, speed range and efficiency values competitive to those of PM motor has been investigated for hybrid electric vehicles in [5]. Comparison studies for SR and PM motors have also been carried for electric bicycles [6] and electric brakes [7].…”

Abstract-In-Service Inspection (ISI) plays a critical role in ensuring the safety and security of nuclear power plant and personnel. The limited access and high ambient temperature conditions impel the need for remote inspection techniques using semi automated vehicle. The electrical actuators driving the ISI robotic vehicle must satisfy the requirements of high operating temperature, high torque density, compact size and low weight. Currently, permanent magnet brushless motors are used due to its compact size and high efficiency. However, due to risk of demagnetization at high temperature as well as due to depleting resources of rare earth material alternate topologies without using permanent magnets shall be considered. This paper investigates the performance of Permanent Magnet (PM) brushless motor and Switched Reluctance (SR) motors for high temperature applications. SR motor is designed as per fundamental design equations satisfying the application requirements. Electromagnetic performance is verified by Finite Element Analysis (FEA) and thermal performance is verified by lumped parameter thermal analysis. Finally the performance of SR motor is compared with PM motor in terms of torque, efficiency, weight, cost and temperature rise.

“…The SRM has been considered for flywheel energy storage, for example in grid stabilization [37,38], in islanding operation [39] and power smoothing [40]. An SRM can be built with only µ-metals, and the lack of exotic permanent magnet material makes them robust, fault tolerant and capable of high temperature operation while still achieving high torque [41].…”

A hollow cylinder flywheel rotor with a novel outer rotor switched reluctance machine (SRM) mounted on the interior rim is presented, with measurements, numerical analysis and analytical models. Practical experiences from the construction process are also discussed. The flywheel rotor does not have a shaft and spokes and is predicted to store 181 Wh/kg at ultimate tensile strength (UTS) according to simulations. The novel SRM is an axial flux machine, chosen due to its robustness and tolerance for high strain. The computed maximum tip speed of the motor at UTS is 1050 m/s. A small-scale proof-of-concept electric machine prototype has been constructed, and the machine inductance has been estimated from measurements of voltage and current and compared against results from analytical models and finite element analysis (FEA). The prototype measurements were used to simulate operation during maximal speed for a comparison towards other high-speed electric machines, in terms of tip speed and power. The mechanical design of the flywheel was performed with an analytical formulation assuming planar stress in concentric shells of orthotropic (unidirectionally circumferentially wound) carbon composites. The analytical approach was verified with 3D FEA in terms of stress and strain.
