Product features details
Features of AC solenoid (shading coil method)
The shading coil method is a method in which a copper ring is embedded in the core (fixed core) as shown in the figure to suppress the pulsation of the suction force due to alternating current.
This is the same as the "flywheel diode method" with a commutator works to suppress the pulsation of the suction force.
The shading coil method has features such as good responsiveness, simple structure, and no direction for connection. However, it also has the following drawbacks and is unreliable. There is a burnout accident, there is a snarling, the shading coil comes off.
The Koganei shading coil method is a highly reliable one that solves these drawbacks.
Current waveforms during normal operation and abnormal conditions
The plunger does not operate due to contaminant, and it does not burn out even if the same current as at startup continues to flow. (Solenoid is designed based on the starting current)
Secret story of development
It is a product with combining design know-how and production technology cultivated since the manufacturer founding to meet customer needs, and it is developed after undergoing strict inspection.
