Description
This unit is a 12 Volt continued rated 2 coil solenoid. It has been designed to be used in the appropriate engine, although they are commonly used in many other applications. The term, solenoid refers to a coil whose length is substantially greater than its diameter and produces a uniform magnetic field in a volume of space when an electric current is passed through it. The solenoid is a type of electromagnet where the purpose is to create a controlled magnetic field. In engineering terms it may also refer to a variety of transducer devices that convert energy into linear motion. This is generally referred to as a solenoid valve.
Characteristics of a solenoid
The solenoid can take the small electrical current from the battery and use it to set the engine in motion. The function is the same as a transistor but using an electromagnetic solenoid rather than a semiconductor to perform the switching. When the start button is pushed a small electric current is sent through the solenoid. This causes the solenoid to close a pair of heavy contacts thus relaying a large electric current which sets the engine in motion. Without this unit it would be impossible to start an engine. If the solenoid receives insufficient power from the battery the generator will not start.
Benefits of using the E4611AM3 solenoid
These units are relatively inexpensive to replace if they malfunction. It is best to check the solenoid first to determine whether it is the solenoid at fault or the battery. The units are available in 12 or 24 volt to suit both battery sizes. Without a solenoid the battery power is insufficient to turn the motor and the generator will not start. These small components are none the less imperative to the smooth starting of most generators and alternators. Solenoids are usually used in an energised to run situation and the generator is turned on then the solenoid is energised.
