SINGLE-PHASE LINE START PERMANENT MAGNET SYNCHRONOUS MOTOR WITH SKEWED STATOR
Journal Title: Power Electronics and Drives - Year 2016, Vol 2, Issue 2
Abstract
Background: The article deals with single-phase line start permanent magnet synchronous motor with skewed stator. Material and methods: Constructions of two physical motor models are presented. Field-circuit motor models were applied in Maxwell software. After software calculations two physical motor models were built: with skewed and unskewed stator. Results of the motors running properties are analysed. Results: Laboratory investigation shows that single-phase line start permanent magnet synchronous motor with skewed stator has noteworthy less torque ripple and vibration but simultaneously a little bit lower efficiency. Conclusions: Application of skewed stator in single-phase line start permanent magnet synchronous motor causes: - a little bit lower back EMF, - a little bit lower efficiency, - less torque ripple, - less motor vibration.

Effects of Grid Disturbances on Current Source Rectifier Controlled by FCS-MPC Algorithm
Nowadays, the increasing number of non-linear loads influences the grid, causing grid voltage disturbances. These disturbances may be very dangerous for the equipment and can create faults in converter behaviour. However...
Dynamic Performance of Estimator-Based Speed Sensorless Control of Induction Machines using Extended and Unscented Kalman Filters
This paper presents an estimator-based speed sensorless field oriented control (FOC) method for induction machines, where the state estimator is based on a self-contained, non-linear model. This model characterizes both...
