Description
Magnetic Levitation Mendocino Motor DIY Solar Motor 300-1500RPM for Lab Teach School Education
Specification:
Size: 130*76*75mm
Weight: 289g
Speed: 300-1500 rpm
Features:
-Magnetic levitation design, friction force is extremely low, fast speed
-Adding fan blades at the tail, more beautiful
-The working principle is interesting, educational
-Safe and stable, small jitter
Principle of Suspension:
-Fix both ends to support the magnet, and fix the product in a suitable position. As long as analyzing the magnetic field generated by the supporting magnets at both ends, you will know that the supported magnet is actually in a bowl-like magnetic field in the vertical direction, and the supported magnet will slide to the center of the bowl, that is, the middle of the two ends supporting the magnet receives an upward supporting force.
-However, it is impossible to stabilize the suspension just by being lifted. Even a slight disturbance will make it lose the balance. So we move the supported magnet slightly outward from the middle of the supporting magnets at both ends, the magnet will receive another force which points to the direction of movement, so the tip will lean against the support, the external disturbance can be offset by a little friction at the support. If the adjustment is just right, the friction will be small.
-On the basis of the suspension, we still need 3 things to operate it: solar cells, enameled coils, strong rubidium iron boron magnetism. Form the four solar cells are into a quadrilateral shape. and the positive pole of the solar cell is connected to the negative pole of the other. After the solar cell is treated in this way, the solar cell can be regarded as a solar cell with automatic commutation function.
-Connect this group of solar cells which with automatic commutation function to a coil. During operation, the solar cells that do positive work are always in a position with sufficient light, and the current generated is large; and the ones that do negative work are always on the dark side, the current generated is very small. So the rotor can continuously rotate in one direction.
Instructions:
The product can rotate when exposed to light. The best light source is strong sunlight. It can also be rotated under high-power light like decorative spotlight, etc. Please pay attention to safety when using it.
Package List:
1 x Magnetic Levitation Motor
Note:
-The product needs high-power light sources (sunlight, tungsten lamp, spotlight) and other high-power light sources to illuminate, and general fluorescent lamps, energy-saving lamps, and LED lamps are not enough to drive this product.
-Strong magnets are more fragile. Do not allow strong magnets to attract freely. Strong impact will damage the magnets.
-Acrylic is easy to grind, and it is shipped with film before leaving the factory. Just tear off the film when you receive the goods.
-Acrylic, also known as plexiglass, is a kind of plastic. Please do not put the product in the car or in a high temperature place, which will cause acrylic deformation and product damage. At the same time, please do not drop the acrylic, it will cause the acrylic to break.
