“…T HE wide usage of materials with high magnetic properties such as samarium-cobalt (SmCo), ferrite, neodymium-iron-boron (NdFeB), and alnico (alloy of aluminum, nickel cobalt, and other elements) makes possible to extensively use permanent magnet synchronous motors (PMSMs) in industrial applications. Due to its compact size and ability to generate high power and effective operation at rated speed, the PMSM is successfully utilized in electric cars, robotics, disk drive systems, and other applications which require precise control performance [1,2]. In PMSM drives, there are many type of disturbances such as the unexpected external load torque, unknown frictions, parameter uncertainties, and sensor noises [3].…”

This paper proposes a generalized high-order observer for estimating total disturbance of permanent magnet synchronous motors (PMSMs). This total disturbance is dominated by load torque but also includes many other terms such as frictions, viscous force, Eddy and flux pulling forces, and noises. A comprehensive experimental results and analyses under various scenarios will be presented to find the appropriate order of the observer. We will compare the performance of zero-order observer (ZDO), first-order observer (FDO), and second-order observer (SDO) under three different scenarios of load torque. Additionally, the results of extended state observer (ESO) under the same conditions are also presented. The experimental results show that FDO and SDO achieve similar performance and both of them is notably better than the ZDO and ESO. However, during the severe conditions of load torque, the SDO-based controller can achieve better performance compared to the that of FDO-based controller. Moreover, fuzzy algorithm is applied to online tune the PI gains in the speed loop. The results also show that the SDO-based fuzzy-PI control schemes is effective in disturbance rejection and high-performance speed tracking. All of the experiments are carried out on a 300-W PMSM testbed with a digital signal processor (DSP).INDEX TERMS Disturbance observer, frictions, fuzzy logic control (FLC), high-order observer, permanent magnet synchronous motor (PMSM), proportional-integral (PI) control, speed control.

Launch of electric vehicles have seen a substantial rise for the past few years in emerging economies like India. In countries like India, the growth and penetration of the electric vehicles in the Indian automotive industry specifically for the two-wheeler segments are driven by the demand surge where cost and motor metrics have a substantial deciding factor. The in-wheel hub-motor, which is the prime mover for the two wheelers, decides the comfort zone of the customer in various metrics such as efficiency, torque, speed range, charging, and hence the distance covered. This paper addresses the design formulation of achieving a high torque Permanent Magnet Synchronous Motor (PMSM) conventionally known as the hub-motor, explicitly for electric two-wheeler application. The hub-motor is aimed for the defined D and L (280 × 30 mm) of volumetric constraints to deliver the rated torque of 50 Nm at the spinning speed of 400 rpm. The hub-motor design is aimed for distance range of 108 km/charge, at the vehicle speed of 54 km/hr for the designed diametric and volumetric constraints. This will lead to a typical cost-effective e-vehicle system since the required distance range of 108 km is achievable at the defined rim size and geometry with an enhanced efficiency greater than 90%. The design is carried out by Finite Element Analysis (FEA) using the electromagnetic software MotorSolve. The results computed are analyzed and validated for the optimal loading conditions for the ambient temperature of 50°C. The results confirm the effectiveness of the proposed design formulation and methodology for achieving the high power density hub-motors for satisfying the customer’s comfort zone in establishing the performance metrics of the electromagnetic system.

“…But the studies only verify the validity of the idea of segmentation, lack of a specific discussion of the segmented approach, and the optimization effects are limited [18][19][20][21][22]. Adding bypass ribs to the rotor barrier can make the motor have better speed regulation ability with field weakening, but the structure is more complex [23]. According to the literature [24], the influence of the distance between adjacent poles and the buried depth of pole centre on the motor d and q-axis inductance and speed regulation ability with field weakening was analysed.…”

To improve the efficiency, a 13 kW used vehicle permanent magnet synchronous motor was remanufactured, whose stator core was replaced by a combination of amorphous alloy laminations and silicon steel laminations. But the speed regulation ability with field weakening of the remanufactured motor limits its development towards high speed direction. Taking the remanufactured motor as the object, based on the theory of speed regulation with field weakening, the maximum speed range was improved by increasing direct‐axis inductance, and the structural optimization parameters affecting the direct‐axis inductance were analysed. The two‐dimensional inductance superposition method was proposed to calculate the direct‐axis and quadrature‐axis inductance of the remanufactured motor, and its accuracy and feasibility were verified by finite element simulation. The segmented structure of the V‐type permanent magnet was used, and the motor structure was optimised from three aspects: the width and position of magnetic bridge and the magnetic pole implantation depth. The orthogonal experiments were designed to determine the best parameter combination. The results show that the direct‐axis inductance of the optimised remanufactured motor is increased by 16.33%, and the performance of speed regulation with field weakening is improved significantly.
