dimensions can be determined for a given maximum MG rotor peripheral speedUMGmax. Firstly,rMG=UMGmax/ωmaxand then the length of the MG rotor can be found usingEq. (11.16)by knowing the maximum torqueTmaxwhich will occur at the lowest operating speed of the flywheel as explained inSection ...
The heating effect on the motor due to current pulsations can be explained on low slip NEMA design B motors. For the NEMA design B motors, the differential speed (called slip) is between 1% and 2% at full load. Due to the torque variation at each revolution the instantaneous speed will ...
If electric motor power factor sounds a bit intimidating or mysterious, see details at DEFINITION of POWER FACTOR or in the formulas below, if you don't know the power factor pf or PF for your motor, a reasonable starting point is 80% or 0.8. (The actual PF when a motor is startin...
The power factor control and inverter operation are performed by applying two modulating signals to the SPWM control logic of the converter. In this dissertation, the converter operation and a proposed control strategy will be explained. Simulation and experimental results for a DSP based induction ...
Induction Motor control. Information on motor starting, energy saving technology, power factor correction and support software for induction motor control.
we extracted ERSP values in the beta frequency range (13–30 Hz), per experimental condition, per training session and block, per subject, and for the motor-cortical electrodes FC1, FC3, C1, C3, CP1, CP3, based on the procedure explained in “Data analysis and statistics” in the “Met...
These high correlations suggest that, under these virtual settings, measuring this single motor parameter provides a close estimation of the individual mental-imagery capacity, as 81% of the inter-subject mental-imagery variability is explained by the individual variability in the measurement of this ...
In hybrid stepper motors, most of the developed torque is contributed by the variable-reluctance principle explained earlier. The rest is developed by the rotor magnet in striving to find the minimum-reluctance position. It should be noted that the alternate polarities of the magnetic poles created...

also explained by the deterioration of proprioceptive inputs with age (Deveze et al.2014; Iwasaki and Yamasoba2014; Clemens et al.2011; Alberts et al.2016). The biological mechanisms at play are multiple. Recently, Karmali et al. (2017,2018) explained changes in gaze stabilization strategies...
