Thermal analysis of induction and synchronous reluctance motors [PDF]
In this paper, the thermal behavior of two induction motors (2.2 and 4 kW, four poles) and two synchronous reluctance motors [(SynRMs) transverse-laminated] are investigated and compared.

Impact of cross-saturation in sensorless control of transverse-laminated synchronous reluctance motors [PDF]
Synchronous reluctance (SyR) motors are well suited to a zero-speed sensorless control, because of their inherently salient behavior. However, the cross-saturation effect can lead to large errors on the position estimate, which is based on the ...

Cross-Saturation Effects in IPM Motors and Related Impact on Sensorless Control [PDF]
Permanent-magnet-assisted synchronous reluctance motors are well suited to zero-speed sensorless control because of their inherently salient behavior. However, the cross-saturation effect can lead to large errors on the position estimate, which is based ...

Recognition of Acoustic Signals of Synchronous Motors with the Use of MoFS and Selected Classifiers
This paper proposes an approach based on acoustic signals for detecting faults appearing in synchronous motors. Acoustic signals of a machine were used for fault detection. These faults contained: broken coils and shorted stator coils.

Sensorless position control of permanent magnet motors with pulsating current injection and compensation of motor end-effects [PDF]
The sensorless position control of permanent-magnet motors is successfully implemented by superimposing a high-frequency voltage signal on the voltage reference or adding a high-frequency current signal to the current reference.

Design Tradeoffs Between Constant Power Speed Range,Uncontrolled Generator Operation and Rated Current of IPM MotorDrives [PDF]
A closed-form approximate formulation is proposed to establish a relationship between the uncontrolled generator operation of IPM motors at high speed and the constant power speed range and drive current capabilities.
