Conventional high-speed flux-switching machines have either a high fundamental frequency or more even harmonics. This paper proposes novel six-slot four-pole axial permanent magnet machine for applications. The machine, consisting of two radially distributed stators and one rotor, can effectively eliminate harmonics in the flux linkage. First, structural parameters that affect performance motor...

The flux switching permanent magnet motor is a kind of double-salient machine with good speed regulation performances and application prospects. However, in traditional sub-domain models which are used to exactly calculate the magnetic field motor, orders major harmonics can not be intuitively obtained. computational efficiency practicality limited. Meanwhile, some errors caused equivalent proc...

A novel back-stepping adaptive control strategy is proposed to direct torque control (DTC) of surface permanent magnet synchronous motor (SPMSM) in order to solve some problems existed in conventional DTC, such as high flux , torque and current ripple, variable switching frequency, and acoustic noises. PI speed regulator and two hysteresis regulators in the conventional DTC system are substitut...

The paper deals with analysis of dynamic behavior of a feedback flux weakening control of PMSM traction drive for light vehicles. The PMSM flux weakening is very important for traction drives. Two torque control structures were analyzed pure feedback control and feedback control with prediction of the field producing current component. The principles, control structures, simulation and experime...

In Line start permanent magnet synchronous motor, eccentricity is a common fault that can make it necessary to remove the motor from the production line. However, because the motor may be inaccessible, diagnosing the fault is not easy. This paper presents an FEM that identifies different models, static eccentricity, dynamic eccentricity, and mixed eccentricity, at no load and full load. The met...

in this paper, a new field oriented control scheme with maximum torque for permanent magnet hysteresis synchronous (pmhs) motor has been presented. vector control method provides significant improvement to the dynamic performance of ac motors but in this method d- axis current is controlled such as the ratio of motor torque to motor current is a maximum, then the dynamic performance will be ver...
