In the actual application of the coil, there are appropriate number and varieties of inductance coil right and wrong standard parts, which are wound according to the needs. When self winding, pay attention to the following points: (1) According to the needs of the circuit, the winding method is selected: when winding the air core inductance coil, the winding method...

Structure and manufacturing method of inductance coil Abstract: a structure and manufacturing method of inductance coil. The method is to wind the induction coil on the surface of rod-shaped magnetic core in order. The induction coil forms a reverse position at an appropriate position, and an appropriate resistance is connected in parallel with one end of the induc...

Metal plate inductive coil used in harsh environment The utility model relates to a metal steel plate inductive coil used in a harsh environment, which is provided with a conductive coil, which is characterized in that:(1) It is a thin steel wire coil surrounded by a plane formed after the space separation of the steel plate engraving, and is provided with four lay...

Inductance coil is a device that works by using the principle of electromagnetic induction. When a current flows through a wire, a certain electromagnetic field will be generated around the wire, and the wire itself of the electromagnetic field will induce the wire within the range of the electromagnetic field. The effect on the wire itself that generates the elect...

The performance index of inductance coil is mainly the inductance. In addition, the wire winding the inductance coil generally has a certain resistance, which is usually very small and can be ignored. However, when the current flowing through some circuits is large, the small resistance of the coil can not be ignored, because a large current will consume power on t...

Blocking effect The self induced electromotive force in the inductance coil always competes with the change of current in the coil. The inductance coil has a blocking effect on AC current. The size of the blocking effect is called inductive reactance XL, and the unit is Ohm. Its relationship with inductance L and AC frequency f is XL = 2 π fl. inductors can be main...

When selecting and using inductive coils, we should first think of the inspection and measurement of the coils, and then judge the quality and advantages and disadvantages of the coils. In order to accurately detect the inductance and quality factor Q of inductance coil, special instruments are generally required, and the test method is more complex. In practical w...

Inductance is the ratio of the magnetic flux of the conductor to the current producing the alternating magnetic flux generated in and around the conductor when the alternating current passes through the conductor. When DC current passes through the inductor, there is only a fixed magnetic line of force around it, which does not change with time; However, when AC cu...

Insulation structure is a structure formed by the combination of the same or several insulation raw materials through a specific process, which is called insulation structure. Focus on inter turn insulation, ground insulation and outsourcing insulation. If it is a three-phase motor, it will also touch phase to phase insulation. So what are the insulation structures...
