In the field of sensorless drive of synchronous machines (SMs), many techniques have been
proposed that can be applied successfully in most applications. Nevertheless, these …

The Winding Function Approach has been used since 1965 to describe the inductance
behavior of small air-gap electrical machines, and several works have contributed to its …

Detection of the rotor position is an important prerequisite for controlling the speed and
developed torque in permanent magnet synchronous motor (PMSM). Even though use of …

During the last decade, field oriented control has often been implemented with space vector
modulation due to its inherent advantages over other modulation techniques. On the other …

Due to their unique properties, like no mechanical contact and therefore no wear and no
lubrication needed, Active Magnetic Bearings (AMBs) have been a dynamic field of research …

For decades, sensorless position estimation methods gained lots of interest from the
research community, especially in the field of electric drives and active magnetic bearings …

In PMSM identification of rotor position is very essential to control speed of the motor. Use of
encoder and resolver is conventional method to detect speed and rotor position but it …

Information obtained about magnetic anisotropy via neutral point voltage measurements can
be used to estimate the position of synchronous and induction machines at all speeds …

The Direct Flux Observer technique for sensorless control of PMSMs (permanent magnet
synchronous motors) allows obtaining a measurement of the ratios of the flux linkages of the …

Estimation methods based on the magnetic anisotropy of the machine can be used to
estimate the rotor position down to low speeds including standstill. Beside the classical …
