The converter used for the compensation, if there is difference occurs between the mechanical and electrical frequency
, which is done by injecting a rotor current with a variable frequency.
planned a trap using a Flash dummy mimicking an electrical frequency
that King Shark honed in on.
[n.sub.sync]: Synchronous speed of motor P: Number of poles [[omega].sub.ref] Reference speed [[omega].sub.r]: Rotor speed [[omega].sub.s]: Slip speed [[omega].sub.e]: Inverter command frequency [V.sub.abc]: Inverter output voltage [V.sub.abc*]: Inverter command voltage [f.sup.*]: Command frequency to inverter [V.sub.dc]: DC bus voltage of inverter f: Electrical frequency
PI: Proportional integral controller e: Error signal [m.sub.a]: Modulation index [m.sub.f]: Frequency modulation ratio [f.sub.c]: Carrier frequency [f.sub.h]: Frequencies at which harmonics occur [f.sub.1]: Fundamental frequency.
At the international level, Huang et al, 2012, analyzed the effect of electrical frequency
on ozone concentration and efficiency of a DBD generator.
When running as a generator connected to the grid, the electrical frequency
of the generator is synchronized to the grid frequency .
The experts also note a technical problem concerning compatibility between the electrical frequency
produced by land-based supply and the frequency used by ships and they also emphasise the potential danger of manipulating high-voltage cables.
Inverters alter electrical frequency
in response to data from the PLC on the rotation and tilt angles in order to control the motors that move the solar panels.
Mr Trower, a teacher of advanced physics with 11 years' experience in microwave technology during the Cold War, told The People: "TETRA uses pulsed microwave radiation at 17.6 cycles per second, which is close to a key electrical frequency
in the brain.
In The Theory of Homogeneous Turbulence, 2002, metaphor came true in a nighttime winter installation in the woods at the Villa di Medici in Rome (at Chiara Parisi's invitation): Assael hid three powerful fans behind bushes; a white light rotated and flashed high in the trees while its electrical frequency
was miked and amplified.
By applying some of the same technology already developed for their electric automobiles, Toyota was able to design and build an AC drive system with a compact controller that manages power regulation by adjusting the electrical frequency
directed to the motor.
The effective electrical frequency
is related to the mechanical shear rate by considering the shearing forces on adjacent molecules.
