The nut inside the electric pistonis an ordinary nut, and there is always a large gap between the rod and nut in the internal structure. The motor used is mostly an AC and DC motor, so the position repeatability is low and the service life is short; The electric pistonis mainly to realize the push-pull action, and the maximum thrust is basically difficult to exceed 10 tons; The first patents of free-piston linear generators date from around 1940, however in the last decades, especially after the development of rare-earth magnets and power electronics, many different research groups have been working in this field. [3] [4] Pneumatic vibrators are well-suited to various bulk material handling and manufacturing applications.

This report focuses on the key global Electric Piston Vibrator players, to define, describe and analyze the value, market share, market competition landscape, SWOT analysis and development plans in next few years. Solenoids are basically electromagnets: they are made of a coil of copper wire with an armature (a slug of metal) in the middle. When the coil is energized, the slug is pulled into the center of the coil. This makes the solenoid able to pull (from one end) or push (from the other). In the combustion chamber, a mixture of fuel and air is ignited, increasing the pressure and forcing the moving parts (connection rod, linear generator and pistons) in the direction of the gas spring. The gas spring is compressed, and, while the piston is near the bottom dead center (BDC), fresh air and fuel are injected into the combustion chamber, expelling the exhaust gases.

The linear generator can generate a force opposed to the motion, not only during expansion but also during compression. The magnitude and the force profile affect the piston movement, as well as the overall efficiency. Pneumatic vibrators come in rotary ball, roller, piston and turbine varieties to improve material flow in applications where compressed air is readily available.
