An online diagnostic approach of open-phase faults for a five-phase permanent magnet synchronous motor (PMSM) fed by closed-loop vector-controlled drive is presented in this article. This accomplished based on the magnetic field pendulous oscillation (MFPO) phenomenon, which significant “swing-like” observed case faults. According to an analysis signatures MFPO patterns under faulty conditions,...

Aiming at the speed regulation problem of permanent magnet synchronous motor (PMSM) drives, a novel backstepping nonsingular terminal sliding mode control (BNTSMC) method with finite-time disturbance observer (FTDO) is proposed. In order to ensure excellent tracking and anti-disturbance performance, controller based on equivalent model recursive principle designed for PMSM. The benefits this ap...

Abstract With the implementation of “dual carbon policy”, traditional injection molding machine transmission system pays more and attention to improving energy efficiency for drive motor, PM motor has obvious advantages in because its high high-power density. A permanent magnet servo (PMSM) an with a rated power 7 kW is designed based on theory PMSM this paper. The 2D finite element analysis (F...

In the permanent magnet synchronous motor (PMSM) sensorless drive method, inductance is a decisive parameter for rotor position estimation. Due to core magnetic saturation, current easily invokes variation and degrades estimation accuracy. For constant load torque, saturated error in method are constant. Inductance results minor degradations, such as less optimal torque current, but no speed er...

The direct torque control theory has achieved great success in the control of permanent magnet synchronous motor. A Direct Torque Control (DTC) scheme of Permanent Magnet Synchronous Motor (PMSM) is presented. Based on in-depth analysis of PMSM mathematical model in abc frame and  frame are established and the operation principle of DTC-SVPWM system, the relationships between the torque and f...

To reduce pollution and energy consumption, particularly in the automotive industry, saving is main concern, hence, Electric vehicles (EVs) are getting significantly more attention than with internal combustion engines (IC engines). motors used Vehicles must have high efficiency for maximum utilization of from batteries or fuel cells. Also, these be compact, lightweight, less expensive very eas...

In an attempt to limit the effects of global warming, virtually all car manufacturers have introduced in last years Hybrid or full Electric Vehicles. The current study shows experimental testing a spoke-type PMSM that was developed based on requirements L6e European light vehicle class. A test bench for this purpose, using DC machine fed by bidirectional Power Supply allowed prototype both moto...

The direct drive hub motor is a that directly combines the and wheel. It accompanied by development of permanent magnet modern control technology. Permanent synchronous (PMSM) especially suitable for use as its advantages high efficiency, energy saving, power easy control. In this paper, Motor Cad software was applied to optimize design an outer rotor PMSM cellular power, simulation analysis ai...
