DescriptionFan Blade High-speed Turbine Hall Electric Machine Unicoil Brushless Motor Physical Experiment Model SpecificationName: Fan Blade High-speed Turbine Hall Electric MachineExperiment Type: PhysicalPrinciple Design: Electromagnetic Induction, Mechanics, Hall Sensor.Size: 132×46×36mmPower: 5W
Voltage:12V Theory1.Hall effect is a semiconductor sensor, under the action of loren magnetic force, the electron flow at the side of the through hole semiconductor to offset, potential difference on the film side, this is the hall voltage.
 2.Hall voltage changes along with the change of magnetic field intensity, the stronger the magnetic field, the higher the voltage, the weaker magnetic field, the less voltage, hall voltage value is very small, usually only a few millivolts, but by the amplifier amplification in the integrated circuit, can make the output voltage amplification enough strong signal Featuresa.Simple Structure, Durability and Safety.b.A special gift-physical educational experiment model for male and children.c.With one more coil, the force is greater and the speed is faster.d.Fan Blade Blushless design,enviromental-friendly DIY craft.
