SU - 0630 voltage 12 v, current 0.5 A. Overall dimensions: 19 * 16 * 30 mm frame type electromagnet industry widely applied,
Electromagnet design the necessary parameters
A, the concept of travel:
Relative to the fully suction position displacement of moving iron core.
 
Second, the power:
Electromagnet electricity will generate power, under the same power consumption, size of the size of the stroke position power;On the same trip, different power consumption strength will be different;Different power consumption for different TongDianLv (both duty cycle).Usually rule is: (1) trip write forces left (2 write write power. Power consumption in the electromagnet applications, safety performance should be considered, namely the power of the test should be an electromagnet under certain TongDianLv, temperature stability after the measured power is the power of the electromagnet, under normal circumstances, the initial power is about 1.5 times of power. After temperature stability such as product TongDian s very low (on and off a few times a day, and time is very short) safety coefficient can be reduced to 1.2 times.
Three, TongDianLv:
The concept of TongDian hown in the following formula.It indicates that the current time (On time) divided by a period of time (On time + Off time), TongDian opular term for the duty ratio.For example, an electromagnet electricity time to 1 second, electricity for 3 seconds, then it TongDian or 1 / (1 + 3) = 25%
TongDian s a very important parameter, because when the electromagnet is incentive is lead to coil heating, if too much heat burning coil.Load cycles or electricity longest time, and the electromagnet power and the rise of temperature of the cooling determines the electromagnet work, but also determines the TongDianLv.
Fourth, insulation class
Electromagnet working temperature, and the environment temperature insulation temperature rating. The magnet need to have the following classification:
A = 105 ℃, E = 105 ℃, 130 ℃ = B, F = 155 ℃, H = 180 ℃, 200 = 200 ℃, 220 = 220 ℃, 250 = 250 ℃
Five: power type and power
Different input current waveform determines the working pattern of the electromagnet: application may include: AC AC/DC DC (constant voltage source and constant current source, battery, battery, DC generator, condenser), rectifier filter, voltage range, maximum available for current factors such as the use of diode rectifier.
Electromagnet applications, the ac electromagnet can directly use alternating current.Dc electromagnet is converted to a dc rectifier are necessary. The output power (power) within a certain range and current is proportional to the. After the electromagnet to magnetic saturation power no longer increases with current (power). Also, is directly proportional to the temperature and electric current (power).
Six, electromagnet protective measures
Such as some special occasions, electromagnet need to adopt some necessary protective measures, such as increasing overheating protection, over-current protection and electromagnet drive control circuit protection.
Seven, environmental factors, and longevity
Environment factors and life needs to be in the electromagnet materials and surface treatment methods select type of important factor. Environmental factors include temperature, humidity, magnetic and electric fields;Gas, liquid and solid pollution or corrosion. Impact vibration, vibration, etc.
Eight, connection mode: installation, power supply, load. And size
Installation: a). The external bolt b) electromagnet screw hole on the shell c) card slot embedded power connection a). B) lead wire + terminal c) Pin feet d. 187 feet
