When installing, the direction of the cylinder should be in line with the beam; the long screw should pass through the beam hole and then pass through the bracket. When fixing the screw, it must be firm; push the piston gently into the cylinder. After the outer cylinder and other pistons are pushed forward, gently pull the lower piston back and forth by hand to check whether it is flexible. If it is not flexible, it can be lubricated with lead powder. It is forbidden to add any lubricating oil to the piston part; the large flywheel is mounted on the measurement position. Install the connecting rod to the positioning of the flywheel. Use a cotton swab to apply a little oil on the two positioning points. Do not add oil to other parts. Place the metal magnet piece on the bottom of the alcohol bottle so that the magnetic alcohol bottle will be firmly attached. On the engine base.\u003cbr\u003e.This product belongs to the external combustion engine, which makes the external combustion of the fuel heated, and the expanded air (helium or hydrogen) acts as a medium to move the piston.

It was first invented by American inventor Larry Spring in 1992, and it is named after the place where it was invented in Mendocino County, California, USA. A Mendocino motor consists of a rotor and a base (stator). Using the repulsive force generated between six groups of annular permanent NdFeB magnets, the rotor is held up and suspended in the air. On the basis of maintaining the suspension, the sun is used to illuminate the solar panel to generate an electric current, and then the energized coil generates an ampere force in the magnetic field to drive the rotor to rotate. During the rotation of the rotor, it is roughly considered that only the solar panel facing the sunlight is in an output state, so that a current appears in a corresponding coil. The rotation makes the area of ​​the solar panel irradiated by the sun constantly change, and the number of turns of the coil that generates the current also changes constantly. However, through the design of the structure, it can be ensured that the coil with current passing through the coil has a fixed current winding direction, and the position of the coil relative to the magnetic field is also fixed. The ingenious combination of the fixed position of the light source and the connection of the internal circuit plays a role in the commutation of the carbon brush.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan class=\"a-list-item\"\u003e\u003cspan\u003eIt's funny to see people's looks and reactions when their squeeze a little shot for this Mendocino Motor model. \u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eSet the rotor to the board, give it a little light, and then it works like charm. \u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eAll of you guests want to know what happen, ice break success.

You can’t expect this solar model rotor run in a constant speed smooth. It’s not an electrified product which can set constant speed, and no rotor shake.\u003cbr\u003eIn the powerful noon time, the model rotor will run freely, speedily, and stably. Oppositely, it performs a little bad in the morning or late afternoon, because of no enough power from the sun. It may act out no stable, a little shake, run slowly.
