The starter motor is a device that can turn the internal combustion engine until the combustion process takes over. This is usually achieved by providing the necessary mechanical energy to rotate the crankshaft for a given number of cycles. When the starter motor turns the crankshaft, the engine starts the combustion process. The article will explain in detail what the starter motor is and the principle of the starter motor.
The main purpose of starting a motor is to stop and start the combined motor. These are special electromechanical switches, the same as relays. The main difference between a relay and a starter is that the starter provides overload protection for the motor. Therefore, the function of the starter is twofold, that is, to automatically or manually change the power of the motor, while protecting the motor from overload or failure.
Any equipment powered by electricity will not work without a starter motor and its components. The starter motor is one of the main components of an electric internal combustion engine. Since the engine cannot spin on its own, a part is needed to start the first cycle. The starter motor helps to start the engine, and then the engine continues to run on its own power.
The starter motor is an electrical device used to rotate (crank) an internal combustion engine to start the engine operation under its own power. As soon as the engine starts to run, it is disconnected from the engine, and the engine now relies on the combustion process. The component is installed on the gearbox housing of the engine, and the gear of the starter motor is connected with the teeth of the flywheel.
As an electrical element, the starter consists of a powerful DC (direct current) motor and a solenoid. The solenoid receives the positive power directly from the battery and the furnace current from the engine body. In order to turn the engine, a 12-volt battery must be used to run the starter. This means that the battery must be sufficient to power the device. In most cases where the starter motor clicks but fails to start, the problem is either from the battery or from the starter itself. The starter motor has only one function, that is, the first revolution and the second revolution required by the engine.
The starter motor itself has a device called a crank gear. Only when the starter rotates the engine, its pinion will mesh with the ring gear on the flywheel. Once the engine accelerates, it will disengage. There are two ways to disengage from the inertial system and the pre-engagement system.
The working principle of the starter motor
According to the rated value and size of the motor (AC motor), the starter motor has different capacities and sizes. These starters can safely switch the power required by the motor and prevent the motor from absorbing large currents. The principle of the starter motor is very simple, and the knowledge of the working principle of the starter motor will be introduced in detail below.
The starter motor is powered by a solenoid, which helps push the starter gear forward to mesh with the engine flywheel. This flywheel is mounted on the crankshaft of the engine, so when the starter motor rotates, it will turn the flywheel like a crankshaft. As soon as the engine starts, the system disengages from the flywheel. Please note that in an automatic transmission, the starter motor can only run when the vehicle is in a parked or neutral position. In a manual transmission, the clutch pedal must be depressed.
Working inside the starter motor, there are four field windings connected to the housing from the inside. The armature (rotating part) is connected in series with the excitation coil through carbon brushes. But keep in mind that in some starters, the magnetic field coil is replaced by a magnetic field. There is a pinion in the front of the armature with an overrunning clutch.
