First and second input currents to a three-phase AC induction motor of either delta or wye winding configuration are directly regulated by a pair of phase-triggered, gate-controlled, semiconductor switches series-inserted between the motor and two phases of its three-phase AC power source, the ...

AN1904 Application note ST7MC three-phase AC induction motor control software library Introduction This Application Note describes a 3-phase induction motor control software library developed for the ST7MC. This 8-bit microcontroller contains a peripheral dedicated to 3- phase brushless motor control...
In order to drive the motor with AC signals, PWM methods are used to drive the switching transistors shown in thethree-phase inverter This modulation and resulting modulated waveform are shown in Figure 5A sinusoidal waveform can be generated by loading a series of duty cycle values into the PW...
Two phase currents now turn into dc quantity (time-invariant). At this point the torque control becomes easier where constant isd (flux component) and isq (torque component) current components controlled independently. 3.1.1.2 Basic Scheme of FOC for AC Motor Figure 3-6 summarizes the basic ...

the organism would not need to turn as the next one would appear at the same (zero degree) angle. In a “two angle” setup, the first three food sources are placed at 0\(^{\circ }\), but in a second evaluation phase, all food sources appear at 180\(^{\circ }\)(see Fig.3b...
The magnitude of the local magnetic field, normalized by its largest value, is represented by different colours and the orientation at the moment that the consine-waveform external field has zero phase is denoted by the black arrow lines. They exhibit similar field interaction patterns as their ...
A Hypersil GOLD aQ column (20 mm × 2.1 mm i.d., 12-µm particles, from Thermo Fisher Scientific, San Jose, CA) was used as an extraction column for online solid phase extraction. Injec- tion volumes were 1.0 mL for all samples. A triple-stage 13 Archives of ...
