“…In [10][11][12][13][14][15][16][17], the turn short fault models of the PMSM have been presented. They used the winding function [10,15] or simplified model [11,12,13,16,17] to obtain inductance value with turn short fault. But, they are inaccurate for the multi pole motor since the flux couplings between the turn faulted winding and healthy windings of the same phase are ignored.…”

-A model of a permanent magnet synchronous motor (PMSM) with an inter turn short fault is proposed using a deformed flux model. The deformed flux model includes not only the fault winding flux information but also the inductance variation of the healthy winding considering the configuration of the winding distribution. With the deformed flux model and the positive sequence current assumption, the proposed model is derived in the positive and negative sequence synchronous reference frame (SRF). The finite elements method (FEM) simulation is applied to validate the proposed PMSM model with inter turn short fault.

“…The coil and stator maintained high temperatures because the heat generation in the ISG was concentrated at these parts. A centrifugal cooling fan was installed to prevent malfunction caused by dielectric breakdown due to degradation resulting from the coil's prolonged exposure to high temperatures [8,9]; the fan sent the flow into the flange and bracket, as shown in Figure 8 Because the thermal and heat dissipation characteristics of an ISG employing the forced air-cooling method may change with the operating speed and environment temperature, a thermal flow analysis was conducted with varying operating parameters. The thermal flow analysis showed that the heat generated by copper, iron, and mechanical losses was discharged along the path shown in Figure 9 through conduction and convection (radiation effects were ignored).…”

“…This may cause demagnetization of the permanent magnet and insulation breakdown of the coil conductor, reducing the performance and durability of the motor and casing mechanical failure in the machine [6][7][8][9]. Motors with a high power density generally employ water-or oil-based cooling methods that use a coolant or oil with a high thermal capacity; however, such methods require a separate space for the cooling channel inside the motor and are inconvenient because they require a connection with an exterior heat exchanger.…”

Abstract:The belt-driven-type integrated starter generator motor in a hybrid electric vehicle is vulnerable to thermal problems owing to its high output power and proximity to the engine. These problems may cause demagnetization and insulation breakdown, reducing the performance and durability of the motor. Hence, it is necessary to evaluate the thermal performance and enhance the cooling capacity of the belt-driven type Integrated Starter Generator. In this study, the internal temperature variations of the motor were investigated with respect to the operating parameters, particularly the rotation speed and environment temperature. At a maximum ambient temperature of 105 °C and rotation speed (motor design point) of 4500 rpm, the coil of the motor was heated to approximately 189 °C in generating mode. The harsh conditions of the starting mode were analyzed by assuming that the motor operates during the start-up time at a maximum ambient temperature of 105 °C and rotation speed (motor design point) of 800 rpm; the coil was heated to approximately 200 °C, which is close to the insulation temperature limit. The model for analyzing the thermal performance of the ISG was verified by comparing its results with those obtained through a generating-mode-based experiment. OPEN ACCESSEnergies 2015, 8 8991

-This paper proposes a parametric model for inter-turn fault detection in a faulttolerant permanent-magnet (FTPM) machine, which can predict the effect of the shortcircuit fault to various physical quantity of the machine. For different faulty operations, a new effective stator inter-turn fault detection method is proposed. Finally, simulations of vector-controlled FTPM machine drives are given to verify the feasibility of the proposed method, showing that even single-coil short-circuit fault could be exactly detected.
