Cara Kerja Motor Starter Mobil Paling Gampang Dipahami

Summary

This video explains how the electric starter system works in motorcycles, breaking it down into three main components: the starter motor, solenoid, and the electrical circuit. The starter motor uses electromagnetic forces to convert electrical energy from the battery into mechanical energy, turning the engine. The solenoid acts as an electrical clutch, engaging and disengaging the motor from the engine’s flywheel. Finally, the electrical circuit ensures the proper flow of current to start the engine. This process is key to understanding how motorcycles start with just the push of a button.

Takeaways

• 😀 The electric starter system in motorcycles uses electrical energy to start the engine without the need for manual effort.
• 😀 There are two main ways to start a motorcycle engine: using the kickstarter or the more practical electric start button.
• 😀 The electric starter system works by sending electricity from the battery to a starter motor, which spins the engine's crankshaft to start the combustion process.
• 😀 The motor starter converts electrical energy into mechanical energy through electromagnetic principles, causing the engine to rotate and fire up.
• 😀 The solenoid starter acts as an electromagnetic clutch that connects and disconnects the starter motor’s shaft from the engine’s flywheel.
• 😀 The solenoid uses two types of coils—holdin coil and pull-in coil—to engage the starter motor with the engine efficiently.
• 😀 The solenoid engages and disengages the motor starter from the engine once the engine is running, preventing it from interfering with the operation.
• 😀 When you press the start button, electricity flows from the battery to the solenoid, which in turn powers the starter motor.
• 😀 A relay in the electrical circuit ensures that electricity flows directly to the solenoid without passing through the ignition switch, optimizing the process.
• 😀 The electrical pathway of the starter system involves key components: the battery, relay, solenoid, and starter motor, all of which work together to start the engine smoothly.

Q & A

What is the main function of an electric starter system in motorcycles?

The main function of an electric starter system in motorcycles is to start the engine by using electricity to power a starter motor, which turns the engine's crankshaft and initiates combustion.

How does pressing the start button lead to the motorcycle engine starting?

Pressing the start button sends electricity from the battery to the starter motor, which then activates the solenoid and engages the motor's gear with the engine's flywheel, causing the engine to rotate and start.

What is the role of the motor starter in the electric starting system?

The motor starter converts electrical energy from the battery into mechanical energy to rotate the engine's crankshaft. It operates through electromagnetism, where electric current generates magnetic fields that cause the rotor to spin.

What is the purpose of the solenoid in the electric starter system?

The solenoid acts as an electric clutch that connects and disconnects the starter motor’s rotation from the engine’s flywheel. It engages the starter motor’s gear with the flywheel and then disengages once the engine starts.

How does the solenoid operate using electromagnetism?

When electricity is applied to the solenoid's coil, it generates a magnetic field that pulls a metal core, causing mechanical movement. This movement pushes the starter motor’s gear to engage with the engine's flywheel.

What are the differences between the 'hold-in coil' and 'pull-in coil' in the solenoid?

The 'hold-in coil' remains active while the starter motor is running, maintaining the solenoid’s action. The 'pull-in coil' is only active momentarily at the beginning to quickly engage the starter motor’s gear with the engine.

What is the purpose of the relay in the electric starter system?

The relay acts as a switch that allows current from the battery to bypass the ignition key and flow directly to the solenoid. It helps deliver a higher current to the solenoid to activate the starter motor.

How does the relay ensure that the solenoid receives the necessary current?

When the ignition key is turned, the relay uses electromagnetic force to close a contact that connects the battery to the solenoid, allowing a strong current to flow and activate the starter motor.

Why does the starter motor stop working after the engine starts?

After the engine starts, the solenoid disengages the starter motor from the engine's flywheel, preventing the starter motor from turning continuously. This is necessary to avoid damaging the motor and to stop it from being powered by the engine.

What happens inside the motor starter when the start button is pressed?

When the start button is pressed, electricity flows from the battery to the starter motor, causing the rotor to spin. This rotation turns the engine's crankshaft and starts the combustion process that powers the engine.
