The Motor Mavericks: Unleashing the Power of Mud Motor Stators In the complex world of directional drilling, one rotational rockstar takes center stage: the mud motor stator. This torque-taming, rotation-reigning component is the ace up your drilling sleeve, guaranteeing that your wellbore stays ...
A method of expanding types of synchronous motors capable of reducing the number of required stator types to use stators in common, and a synchronous motor produced by the method. A group of stators are prepared by stacking stator cores of identical shape so that heights of the stators are...

The ferrites became popular due to their low cost and cost increasing of NdFeB. The progress in ferrite properties in...
StatorsThe relationships of the γM, 7Sγ1 and 7Sγ2 immunoglobulins to the pathogenesis of herpetic skin infections and encephalitis were investigated in guinea pigs. The differences in the sequential appearance, avidity and secondary response of these immunoglobulins to booster inoculations of viral...
StatorsHarmonic analysisShapeTorqueThis paper investigates and compares the vibration performance of permanent magnet assisted synchronous reluctance machines (PM-SynRM) with different rotor topologies. First, the electromagnetic force of PM-SynRM is calculated through the Maxwell stress tensor method (MSTM...
