Design and Comparison of Different Switched Reluctance Machines Topologies for Automotive Applications
نویسندگان
چکیده
The present paper approaches the comparative design and analysis of 5 SRM topologies for an EPAS application. Different number of phases and different combination of stator and rotor pole number will be considered, keeping the same main dimensions (outer and inner stator diameter, airgap length, stack length, stator pole height, stator yoke width, rotor pole height) and the same winding per phase (number of turns and wire diameter). A preliminary sizing of the machine will be carried on, giving the initial geometric data. The key dimensions will be calculated and the winding will be dimensioned. A numericalbased performances analysis will be performed for each case. Index Terms — switched reluctance machine, electrical power assisted steering systems, fault tolerance, conventional and optimization design, numerical field analysis

متن کاملA New Skewed-Rotor-Pole Switched Reluctance Motor Design
This paper considers a new switched reluctance motor (SRM) structure aiming at high starting torque with low volume. For some applications such as EVs (Electrical Vehicles), the motor volume and starting torque is a critical point in its design. In many methods, reducing the motor volume causes reduction in starting torque and decreases the motor efficiency. Unlike conventional SRMs, the rotor ...
متن کاملDesign, Construction and Comparison of a Sensorless Driver Circuit for Switched Reluctance Motor
In the presented paper, a sensorless driver circuit is designed, constructed and tested to control two types of three-phase Switched Reluctance Motor (SRM). The presented control algorithm has three steps. In the first step, the SRM is controlled by an open-loop method. In the second step, mathematical model of the SRM phase, motor parameters and flux-current-rotor position relation are used in...
