Radiation Principle and Spatial Direct Modulation Method of a Low Frequency Antenna Based on Rotating Permanent Magnet
نویسندگان
چکیده
The theory of mechanical antenna is still in its infancy at present, and radiation mechanism, field distribution, modulation methods other basic theories need to be explored improved. mechanism a rotating-magnet based (RMBMA) explored. An equivalent model the established. formula derived using this rotation matrix. spatial direct method also investigated. Two prototype antennas are fabricated DC/AC servo motors NdFeB magnets, experiments carried out verify correctness derivation analysis. measured simulated results consistent with each other. By precisely controlling moving parameters an AC motor, signal binary amplitude shift keying (BASK) generated, original code sequence recovered by demodulation.

15 صفحه اولA New Hunting Control Method for Permanent Magnet Hysteresis Motors
Hunting is a flutter associated with the synchronous speed that gives rise to the gyro drifting errors and may cause objectionable time-displacement errors in video head wheel drives and other precision scanning systems. In this paper, dynamic characteristics of permanent Magnet hysteresis motors are presented and hunting is explained. New damping techniques have been developed using optimi...
متن کاملAdaptive Voltage-based Control of Direct-drive Robots Driven by Permanent Magnet Synchronous Motors
Tracking control of the direct-drive robot manipulators in high-speed is a challenging problem. The Coriolis and centrifugal torques become dominant in the high-speed motion control. The dynamical model of the robotic system including the robot manipulator and actuators is highly nonlinear, heavily coupled, uncertain and computationally extensive in non-companion form. In order to overcome thes...
متن کاملAnalysis and Design of a Permanent-Magnet Outer-Rotor Synchronous Generator for a Direct-Drive Vertical-Axis Wind Turbine
In Permanent-Magnet Synchronous Generators (PMSGs) the reduction of cogging torque is one of the most important problems in their performance and evaluation. In this paper, at first, a direct-drive vertical-axis wind turbine is chosen. According to its nominal value operational point, necessary parameters for the generator is extracted. Due to an analytical method, four generators with differen...

1.0 overview it seems that grammar plays a crucial role in the area of second and foreign language learning and widely has been acknowledged in grammar research. in other words, teaching grammar is an issue which has attracted much attention to itself, and a lot of teachers argue about the existence of grammar in language teaching and learning. this issue will remind us a famous sentence f...
