June 16, Looking back to the history to jump ahead in the future. They are capable to achieve very high efficiency level and to gain the maximum efficiency class IE4 of IEC standard. Both energy consumption as well as the environmental impact can be significantly reduced by adopting electric motors with high efficiency levels.
The size of the current DU-SRM is optimized as a near-wheel motor, operating through a integrated gear box, with either 2 or 4 motors per vehicle: In that area, the traditional Permanent Magnet motors have a high loss, due to magnetic iron losses.
In general, the DU-SRM has a very high efficiency and torque density compared to other non-magnetic motors.
The zero loss except losses from ball bearings when free-wheeling is even more important in Hybrid vehicles where the electric motor is turned off in a large part of the driving time when the conventional fuel motor is driving the car.
The simple construction only consist of standard copper wire and iron laminate which makes it possible to work in the harsh outdoor environment such as electrical transport.
If a fault should occur in a coil, the structure with electric, magnetic and mechanical separated phases and no permanent magnets makes it possible to handle the fault and bring the vehicle safe to the nearest stop.
The simple modular construction makes it possible to integrate the motor and turbine as one dedicated and efficient unit. The use of standard materials, like copper and iron laminate, makes the DU-SRM resistant to the harsh environment in a turbine application.This paper proposes a new method to minimize torque ripple of a switched reluctance motor (SRM), which is based on the control of the sum of the square of the phase currents by using only two current sensor and analog multipliers.

Advantages of switched reluctance motor applications to EV and HEV: design and control issues The purpose of this paper is to investigate the capabilities of the switched reluctance motor (SRM) for electric vehicle and hybrid electric vehicle.
The switched reluctance motor (SRM) is a type of a stepper motor, an electric motor that runs by reluctance torque. Unlike common DC motor types, power is delivered to windings in the stator (case) rather than the rotor. FOLLOW us.
