This paper deals with the design and analysis of high speed 100,000 rpm blushes DC (BLDC) motor for centrifuge. To determine the specifications, the proposed motor is designed using a loading ratio method based on the rated speed and power. First, the design results of the investigated 3kW 100,000 rpm BLDC motor are compared with the simulation results by a 2-D finite element method (FEM), to confirm...
A 12/10 flux-switching permanent magnet motor (FSPM) is described. Qualitative analysis of magnetic circuit indicates that a connection between stator segments is benefit to motor operation. From the basic principle of flux-weakening speed-extension operation, weaken magnetic factor and speed-extension multiple are calculated. The analysis results show that this kind of motor has higher flux-weakening...
Elimination of externally mounted position sensors and their associated cables is a goal for virtually all drive manufacturers. This paper addresses design methods of surface permanent magnet (SPM) synchronous machines for saliency-tracking self-sensing (position sensorless) position estimation. Machine saliency is created by stator magnetic saturation due to the rotor zigzag leakage flux from surface...
Transverse flux machines(TFMs) feature high torque density and high efficiency at low rotational speed, they are attractive alternatives to conventional machines in direct drive systems and hybrid propulsion applications. The structure and the mathematical principle of the transverse flux switched reluctance machine(TFSRM) described in this paper is based on analytical modeling of the electromagnetic...
