Yesterday when the transformer to find a problem, a boost inductance, my air gap plus the greater the inductance of the smaller, but a counterattack transformer my air gap plus the more inductance but the greater, now a bit can not figure out.
Inductance: inductance, also known as self-inductance coefficient, is the inductance of the original sense of self-inductance of a physical quantity. When the magnetic flux through a coil changes, the coil will produce potential, which is the electromagnetic induction phenomenon. The resulting potential is called the induced electromotive force, the magnitude of the electromotive force is proportional to the velocity of the flux change and the number of turns of the coil. The basic unit of inductance is H (H), there are cents (mH), micro-Heng (uh). 1H = 10 ^ 3mH = 10 ^ 6uH
The air gap is the gap between the motor stator and rotor. The stator does not turn, the rotor needs to turn, so the air gap is necessary, according to the different motor, air gap size is also different. In general, the asynchronous motor air gap is small, synchronous motor air gap.
Energy storage mainly refers to the storage of electricity. Energy storage is a term in oil reservoirs that represent the ability of reservoirs to store oil and gas.
The same winding the same diameter of the conditions, the greater the air gap, the smaller the amount of inductance.
The larger the air gap, the lower the permeability, the smaller the inductance.
You are not a flyback transformer only done once the air gap concluded that there may be two of your core wrapped around the loose is not the same, anyway, it is impossible under the same conditions, the air gap to increase the amount of inductance but large.
