When the excitation coil has current
When direct current is applied to the excitation coil, the current will generate magnetic flux along the magnetic circuit. The magnetic circuit contains the left and right working air gaps. The direction of the magnetic flux generated by the permanent magnets in the left and right working air gaps is opposite, so it passes through one of the working air gaps. The magnetic flux increases, while the magnetic flux passing through the other working air gap decreases, and the action armature assembly moves in the direction of increasing magnetic flux
1. When the size of the solenoid valve allows, try to choose an iron core with a larger section. The large-section iron core allows more magnetic flux, and of course it is possible to generate a large electromagnetic attraction;
2. Within the allowable range of the solenoid valve spool stroke, try to reduce the length of the air gap in the iron core. The reluctance in the air is large, reducing the length of the air gap in the iron core can reduce the reluctance of the magnetic circuit, thus making the magnetic force stronger;
3. We know that the size of the magnetic flux in the iron core and the number of turns of the coil are related to the product of the current passing through the coil. We call the product of the number of turns of the coil and the current passing through the coil as the ampere-turn. In the case of a certain iron core, the larger the number of ampere-turns of the coil, the stronger the suction of the iron core. In the determination of the size of the electromagnet In this case, the size of the electromagnetic coil is also limited. In this limited range, in order to obtain the best electromagnetic attraction, the number of turns of the coil and the wire diameter of the coil (this is related to the allowable current) must have a good value. In order to obtain a large number of ampere turns, so in order to achieve this good effect (large electromagnetic attraction), for the determined coil, sometimes it may be necessary to increase the number of turns to reduce the wire diameter, and sometimes it may be necessary to reduce the number of turns to increase wire diameter. In short, the principle of obtaining large ampere turns is the principle, of course, the influence of the power supply voltage connected to the coil on the coil parameters must be considered.
