چکیده
The paper presents the properties of sensorless drives with permanent magnet synchronous machines with respect to dynamics and overload capability. A main aspect is the low speed range including standstill. Several drives are presented, which have already been in series applications or are going to be used in series. As examples, a medical application (20 mNm / 40.000 rpm drive), a traction application (3.000 Nm / 1.000 rpm drive) and a drive of production industry (2 Nm / 4.000 rpm drive) are presented. All of them are able to provide full starting torque or even overload. Hence, very robust and economical systems can be realized, which have already been used in practice. Measurements and statistical evaluations of sensorless-obtained position and speed information are presented. A comparison with reference sensors is performed. Furthermore, highly dynamic starting behaviour and overload properties (e.g. with 3 times rated current) are discussed.

Politecnico Di Torino Porto Institutional Repository [proceeding] Hybrid Sensorless Control of Axial Flux Permanent Magnet Motor Drives, including Zero Speed Hybrid Sensorless Control of Axial Flux Permanent Magnet Motor Drives, including Zero Speed
The sensorless control of an axial flux permanent magnet motor drive is proposed and tested. The motor is not purposely designed for sensorless control and shows a very small inherent saliency. This significantly affects the saliency-based position estimation in the low speed region. Other nonidealities, such as the non-sinusoidal back-EMF waveforms and possible misalignment between stator and ...

Elektronische Systeme sind angesichts der zunehmenden Anforderungen an ihre Energieeffizienz immer häufiger mit einem aktivem Power-Management (PM) ausgestattet. Hierbei werden Spannungen und Frequenzen skaliert oder inaktive Bereiche zeitweise von der Versorgungsspannung getrennt. Die Steuerung erfolgt zumeist softwareseitig, wobei die Komplexität aufgrund der stetig wachsenden Anzahl von Powe...
متن کاملCombination of voltage model and high-frequency signal injection for sensorless permanent magnet synchronous motor drives
The paper proposes a method for the rotor speed and position estimation of permanent magnet synchronous motors, applicable in a wide speed range including standstill. A modified voltage model is used at high speeds, and it is combined with a high-frequency signal injection technique at low speeds. The fast dynamic response of the voltage model is thus augmented with the steady-state accuracy of...
متن کامل3-Phase Switched Reluctance (SR) Sensorless Motor Control Using a 56F80x, 56F8100 or 56F8300 Device
SR motors are gaining wider popularity among variable-speed drives. This is due to their simple, low-cost construction characterized by an absence of magnets and rotor winding, high level of performance over a wide range of speeds, and fault-tolerant power stage design. Availability and the moderate cost of the necessary electronic components make SR drives a viable alternative to other commonl...
