Sensorless Permanent Magnet Synchronous Motor Drive : A Review
Vector control has been widely used in control of permanent magnet synchronous motors (PMSM) where the information of rotor position is required. Shaft position sensor such as an optical shaft position encoder or Hall Effect sensor is fitted to provide a signal that is used to maintain an appropriate space angle between the stator and rotor fields in the motor. Even though this method is very p...
متن کاملHybrid sensorless permanent magnet synchronous machine four quadrant drive based on direct matrix converter
Permanent Magnet Synchronous Machines (PMSMs) have several advantages, such as high efficiency and low volume and weight, which make them attractive for aerospace applications and high performance servo drives. Matrix Converters (MCs) are an all-silicon alternative, with no bulky reactive elements, to the standard voltage source inverter. The most common control technique for such PMSMMC-fed dr...

متن کاملSensorless Permanent Magnet Drive Design
The development procedure of permanent magnet drives for sensor less operation beginning from standstill under overload conditions has to consider different design aspects coevally. First, the robust rotor position sensing by test signal enforces a design with a strongly different behavior of the spatial dq-oriented differential inductance values. Therefore, the interior rotor magnet array arra...
متن کاملSimple Sensorless Control of Interior Permanent Magnet Synchronous Motor Using PLL Based on Extended EMF
This paper proposes an improved sensorless control to estimate the rotor position of an interior permanent magnet synchronous motor. A phase-locked loop (PLL) is used to obtain the phase angle of the grid. The rotor position can be estimated using a PLL based on extended electromotive force (EEMF) because the EEMF contains information about the rotor position. The proposed method can reduce the...
