“…Multiphase PM machine with the high phase number can offer the high fault-tolerant capability, while the multiphase drive generally need expensive custom solutions, as presented in [86][87][88][89][90][91][92][93][94][95][96][97]. PM machines with multiple three-phase winding can be driven by multiple standard three-phase converters, and thus avoiding the use of custom and expensive converters [91].…”

Permanent-magnet (PM) machines have attracted a lot of interest in various applications since they have the merits of high torque density, high power density and high efficiency. However, issue of poor fault tolerance of the conventional PM machines restricts their practical applications in the field of safety-critical applications, e.g. aerospace, electric vehicle, electrical propulsion and wind power generator applications. An enormous amount of work has been done to improve the faulttolerant capability of PM machines. This paper will review research work on PM fault-tolerant machines up-to-date, including modular design, short-circuit current limitation design, redundant design, ease of thermal dissipation of PM design, and torque enhancement design techniques. The work of this paper can provide some references for future studies and engineering applications of PM fault-tolerant machines for safety-critical applications.

This paper proposes a speed-loop periodic controller design for fault-tolerant surface permanent magnet synchronous motor (SPMSM) drive systems. Faulty conditions, including an open insulated-gate bipolar transistor (IGBT), a short-circuited IGBT, or a Hall-effect current sensor fault are investigated. The fault-tolerant SPMSM drive system using a speed-loop periodic controller has better performance than when using a speed-loop PI controller under normal or faulty conditions. The superiority of the proposed speed-loop-periodic-controller-based SPMSM drive system includes faster transient responses and better load disturbance responses. A detailed design of the speed-loop periodic controller and its related fault-tolerant method, including fault detection, diagnosis, isolation, and control are included. In addition, a current estimator is also proposed to estimate the stator current. When the Hall-effect current sensor is faulty, the estimated current is used to replace the current of the faulty sensor. A 32-bit digital signal processor, type TMS-320F-2808, is used to execute the fault-tolerant method and speed-loop periodic control. Measured experimental results validate the theoretical analysis. The proposed implementation of a fault-tolerant SPMSM drive system and speed-loop periodic controller design can be easily applied in industry due to its simplicity.

“…Recently, a lot of studies have been done using one motor rather than two motors. A single motor internal winding is separated into two parts by a master part and a slave part, respectively, and connected to two ECUs [13][14][15][16]. This is advantageous in that it is possible to implement a redundant system with a single motor, but it is disadvantageous in that it is extremely vulnerable to overheating.…”

In this paper, an asymmetric dual winding three-phase permanent magnet synchronous motor (PMSM) is proposed for enhancing the fault-tolerance of overheat in autonomous vehicles. A conventional dual winding three-phase motor is divided into two three-phase windings, one for the master part and one for the slave part. It is advantageous to have a redundant system by combining two electric control units (ECU) with one motor instead of two motors. However, when the motor is burned out due to excessive overload driving beyond the motor design value, there is a possibility that no operation can be performed even though there are two ECUs. The proposed dual winding three-phase asymmetric motors are designed differently in the master and slave windings so that the simultaneous burnout of master and slave can be avoided. The coil temperature rise according to the asymmetrical winding design of the motor is estimated by the thermal equivalent circuit method. Also, optimal design for proposed model is conducted using the radial basis function (RBF) and the experimental design method. The optimized proposed asymmetric dual winding three-phase PMSM is applied to the design of motor for electric brake systems of an autonomous vehicle and is verified its usefulness.
