Design and Development of a 26-Pole and 24-Slot Bearingless Motor

Elektrische Antriebe - Grundlagen

“…Hierzu gehören zum Beispiel Untersuchungen zu lagerlosen Zentrifugalpumpen [557,558,559,560], Mixern [561,562] oder Motoren mit großem Durchmesser, beispielsweise für chemische Prozesskammern [563,564,565].

Permanent magnet synchronous machines: Performances during driving cycles for a hybrid electric vehicle application

“…The second machine was developed by doubling the pole number on the rotor. Therefore, we have obtained the PMSM (1) with 16PMs on the rotor, so that the slot per pole and per phase number is of S pp =1/4 ( Fig.1.b.). Then, the third machine was considered as the reference machine that was characterized by the distributed windings with 48 slots and 8 poles on the rotor (Fig.2.).…”

“…The hybrid electric vehicle allows combining the advantages of the thermal and the electrical motorization while minimizing their disadvantages [1]- [2]. That is why several researchers have studied novel technologies of electrical machines for this kind of application such as the asynchronous machine, synchronous machine, switched reluctance machine or switching-flux synchronous machine [2]- [6].…”

Bearingless motor's radial suspension force control based on virtual winding current analysis

“…However, an extra motor component must be added to the magnetic bearing system to rotate the rotor, which gives rise to the increased axial length, the complicated structure, and reduced shaft resonance frequencies. In order to eliminate the disadvantages, bearingless motors can be a good alternative [1,2]. Bearingless motors are equipped with two sets of windings in the same stator core, namely torque windings (pole-pair is P M ) and suspension force windings (pole-pair is P B ).…”
