Required Parameters for Electromagnet Design
Required Parameters for Electromagnet Design the concept of 1. trip: The displacement of the movable iron core relative to the full suction position is shown in the following figure: 2. strength: The power of the electromagnet will generate power. Under the same power consumption, the power of different stroke positions is different; under the same stroke, the power of different power consumption will be different; different power consumption corresponds to different power rates (both Duty ratio). The usual rule is: (1) stroke ↑ power ↓ (2) power consumption ↑ power. In the application of electromagnet, safety performance should be considered, that is, the test of strength should be the electromagnet at a certain power rate, and the measured strength after the temperature rise is stable is the strength of the electromagnet. Under normal circumstances, the initial strength is about 1.5 times of the strength after the temperature rise is stable. If the energization rate of the product is very low (only a few times a day, and the time is very short), the safety factor can be reduced to 1.2 times. 3. energization rate: The concept of the energization rate is shown in the following formula. That is, the power-on time (On time) divided by the time of a cycle (On time Off time), the popular name for the power-on rate is the duty cycle. For example, if an electromagnet has a power-on time of 1 second and a power-off time of 3 seconds, then its power-on rate is 1/(13) = 25% The energization rate is a very important parameter, because when the electromagnet is excited, it will cause the coil to heat up, and if the heat is too high, it will burn the coil. The load cycle or the maximum power-on time, as well as the power and heat dissipation of the electromagnet determine the temperature rise when the electromagnet is working, and also determine the power-on rate. 4. insulation class The working temperature rise of the electromagnet and the ambient temperature during operation determine the insulation temperature level required by the electromagnet. There are the following classification levels: A=105℃, E=120℃, B =130℃, F=155℃, H=180℃, 200=200℃, 220=220℃, 250=250℃ Five: power type and power Different input current waveforms determine the working mode of the electromagnet: there may be AC/DC DC (constant voltage source, constant current source, battery, dry battery, DC generator, capacitor), rectifier filter mode, voltage range, maximum available current and other factors using diode rectification. In electromagnet applications, AC electromagnets can be used directly with alternating current. The DC electromagnet must be converted to DC by a rectifier. The output power is proportional to the current (power) within a certain range. After the electromagnet reaches magnetic saturation, the power no longer increases with the current (power). Similarly, temperature rise and current (power) is proportional. Protective Measures of 6. Electromagnet Such as some special occasions, the electromagnet needs to adopt some necessary protection measures, such as the increase of overheating protection, overcurrent protection and electromagnet drive control circuit protection. 7. environmental factors and life Environmental conditions and life requirements are important considerations in the selection of electromagnet materials and surface treatments. Environmental factors include: temperature, humidity, magnetic or electric fields; gas, liquid and solid pollution or corrosion. Shock, vibration, etc. 8. connection: installation, power supply, load. and size Installation and connection: a). external bolt B). screw hole on electromagnet housing c). card slot embedded power connection a). lead B). lead terminal c) pin pin D. 187 quick connection pin. e. others

Is it necessary to adjust the power in the production process of electromagnetic heater
Whether the power needs to be adjusted during the production of the electromagnetic heater: Recently, customers who come into contact with electromagnetic heaters for the first time often ask, when the equipment reaches the required temperature in the production process, do we need to reduce the power of our electromagnetic heaters? 1. Confirm the original heating form of the equipment that needs electromagnetic heating energy-saving transformation: A. Electric furnace wire/Shi Ying: Confirm the original number of heating zones and the heating power of each temperature zone, and select the electromagnetic heater products of the corresponding power model nearby for matching. If the power is less than 2KW, select 2KW electromagnetic heating control board, and match the number of products with the same number as the original heating zone. This method is mainly used for injection molding machines, film blowing machines, wire drawing machines, extruders and other less powerful equipment. B.

The magnetic field direction of the electromagnet can be judged by ampere rules.
Ampere: The ampere rule, also known as the right-hand spiral rule, is a rule that expresses the relationship between the current and the direction of the magnetic induction line of the current-excited magnetic field. (1) Ampere rule in electrified straight wire (ampere rule 1): hold the electrified straight wire with your right hand, let your thumb point to the direction of current, and your four fingers point to the direction of magnetic lines of force around the electrified straight wire. (2) Ampere rule in energized solenoid (ampere rule 2): hold the energized solenoid with your right hand so that the four fingers bend in the same direction as the current, then the end pointed by the thumb is the n pole of the energized solenoid Nature The ampere rule for linear currents also applies to a small segment of linear current. The ring current can be regarded as the composition of many small linear currents. For each small linear current, the direction of the magnetic induction intensity on the central axis of the ring current is determined by the ampere of the linear current. The superposition gives the direction of the magnetic induction line on the central axis of the annular current. The ampere rule of linear current is basic. The ampere rule of annular current can be derived from the ampere rule of linear current. The ampere rule of linear current is also applicable to the magnetic field generated by the linear motion of charge. At this time, the direction of current is the same as that of positive charge and opposite to that of negative charge.

Advantages of electromagnetic heaters
With the development of industry, electromagnetic heating storm swept, electromagnetic heater is not only used in the industrial field, but also integrated into the heating, bathing heating and so on in our lives. so electromagnetic heater really have so good? fast heating speed Because the electromagnetic heater is to make the barrel itself heat, and the electric heating ring is heated by heat transfer. Therefore, the electromagnetic heater is faster than the electric heating coil. Can be faster than the electric heating coil heating speed of more than 20%. It used to take more than an hour to warm up, but now it only takes 20 minutes to warm up. Good energy saving effect The electromagnetic heater causes the barrel to heat itself through electromagnetic induction and has a heat preservation effect at the same time. However, the traditional electric heating ring transfers a large part of the heat to the air through heat transfer and the contact between the surface and the air. Because the electromagnetic heater is more energy-saving than the traditional electric heating coil heating method. The electromagnetic heater can save more than 30% of electricity than the electric heating ring, and can save more than thousands of dollars per month. Long service life Because the electromagnetic heating ring itself does not generate heat, and it is made of insulating materials and high-temperature cables, there is no problem that the resistance wire of the original electric heating ring is oxidized at high temperature and shortens the service life. It has a long service life and no need for maintenance. The advantages reduce maintenance time and cost. It has been used by the majority of plastic products enterprises, which greatly reduces the production cost of enterprises.
