Low Frequency Rotating Magnetic Field Generator And Its Application in Blood Pressure Regulation
نویسندگان
چکیده
On the basis of predecessors' research and the existing theory, for convenient and reliable to study the biological effect of low frequency rotating magnetic field, design a high precision and low frequency rotating magnetic field generator, which could be used to stimulate the small area. Choose stepper motor to drive permanent magnet for produce a rotating magnetic field, which can reduce the magnetic field coverage area and improve the positioning accuracy. Adopt high precision stepper motor controller and step motor to control motor speed for high precise frequency of the rotating magnetic field. Using the motor controller can output three road motor control pulse at the same time, to realize frequency is 1-15 Hz, 0.3-0.4 T surface magnetic field strength and three same characteristics rotating magnetic field. Using light touch switch and LCD display for the frequency, the direction of the spin magnetic control

متن کاملA Novel Transformer-Based Single-to-Three Phase Conversion Technique Using Rotating Magnetic Field Theory
This paper presents a new single to three phase converter using rotating magnetic field transformer. Conventional transformers have been used in many converters aiming at supplementary improvements and they usually have no critical effect on the conversion technique. In this paper, the conversion technique is based on a special rotating magnetic field transformer in which there are two windings...
متن کاملEffect of Magnetic Field on the Rotating Flow in a Similar Czochralski Configuration
We present a numerical study of the rotating flow generated by two rotating disks in co-/counter-rotating, inside a fixed cylindrical enclosure similar to the Czochralski configuration (Cz). The enclosure having an aspect ratio A = H/Rc equal to 2, filled with a low Prandtl number fluid (Pr = 0.011), which is submitted to a vertical temperature gradient. The finite volume method has been used ...
متن کاملThe Measurement of Low Frequency Magnetic Field of Two Kinds of GSM900 Mobile Phone
Introduction: The use of mobile communication systems has dramatically increased over the past decade. Although many studies have been performed to determine the effect of radio frequency (RF) but less attention has been paid to the possible biological impact of exposure to extremely low frequency (ELF) components. The objective of this study is two folds. One is to design the ...
متن کاملEffects of 35 Hz, 2 mT Magnetic Field on Peripheral Blood Lymphocytes of Human In Vitro and Rat In Vivo
In this research we have studied the effects of extremely low frequency magnetic field on the peripheral blood lymphocytes chromosomes of human in vitro and rat in vivo. By this means, we used 60 blood samples of 10 men as well as 40 rats. Of 60 human blood samples ,40 samples (in two group of 20) were selected as test groups and placed into the 2 mT and 35 Hz magnetic field. The blood samples,...
