Solenoid Armature: The relationship between suction and travel
The relationship between electromagnetic suction and travel (i.e. air gap) is called suction characteristics. The relationship between spring force and gravity is called reaction characteristic. It is hoped that the electromagnet under any stroke, the suction force is slightly greater than the reaction force, which can ensure the moving iron core absorption, and avoid the action speed too fast to cause impact and rebound. This can avoid contact welding and burning, to improve the life. The suction force of the dc electromagnet is inversely proportional to the square of the travel. The suction characteristic curve of ac electromagnet is relatively flat, that is, it has larger suction force when the travel is large.
Solenoid Armature:Starting current and holding current
When the AC electromagnet voltage is constant, the magnitude of the excitation current is related to the resistance of the coil, but it is mainly affected by the stroke. The stroke is large, the magnetic resistance is large, and the exciting current is also large. The current at the maximum stroke is called the starting current, and the current at the time of suction is called the holding current, also called the exciting current. In large electromagnets, the starting current can reach more than 10 times the holding current.
The starting current of a small electromagnet can also reach 2 to 4 times the holding current. If the moving iron core is stuck and the starting current continues to flow, the coil heats up extremely and is even burned. Electromagnetic pilot valves with small strokes are not easy to burn. AC electromagnets should not be switched on and off frequently. The life is not as long as the DC electromagnet.
When the voltage is constant, the coil current of the DC solenoid depends only on the coil resistance, regardless of the stroke size. When the moving iron core is stuck, it will not burn the coil. The DC electromagnet can be frequently turned on and off, and the work is safe and reliable. However, if the voltage is too high and the current is too high, the coil will still be burnt.
