How does the starter motor work?

The starter motor is an essential part of a car's ignition system. Its main function is to convert electrical energy from the battery into mechanical energy to turn the internal combustion engine and allow the vehicle to start. When you turn the ignition key, an electrical signal is sent to the starter motor, which in turn activates a solenoid. This solenoid allows electrical current to flow to the starter motor, causing the starter pinion to engage the flywheel of the engine and spin it. Once the internal combustion engine starts up, the starter motor automatically disengages.

Main starter motor failures

The starter motor can suffer various breakdowns throughout its useful life. Some of the most common include:

  • Solenoid Failure: If the solenoid malfunctions, the starter will not receive the electrical current needed to start the engine.
  • Carbon wear: The carbons are the parts that make contact with the starter motor rotor. Over time, they can wear down and cause poor contact, making it difficult to start the vehicle.
  • Starter Pinion Problems: If the starter pinion does not engage properly with the flywheel, the starter will not be able to turn it and the vehicle will not start.
  • Starter Failure: In some cases, the starter can have a complete failure and will need to be replaced.

Prices and where to find starter motor information

The price of a starter can vary depending on the model and make of the vehicle. In general, prices range between €100 and €300. For more precise information on prices and where to buy a starter motor, we recommend that you consult specialized automotive websites, such as, where you will find reviews, comparisons and product recommendations.

Starter FAQ

1. How can I tell if my starter is failing?

There are several symptoms that can indicate a faulty starter. Some of them include a clicking noise when turning the ignition key, slow or hard starting, or complete lack of response when trying to start the vehicle. If you experience any of these symptoms, it is advisable to take your vehicle to a specialized workshop to carry out a proper diagnosis.

2. Can I repair my starter instead of replacing it?

In some cases, it is possible to repair certain components of the starter, such as the carbons or the solenoid. However, this will depend on the type of failure and the availability of spare parts. In general, if the starter motor has a complete failure, it is best to replace it with a new one to ensure proper operation of your vehicle's ignition system.


The starter motor is a fundamental part of a car's ignition system. Its correct operation is crucial to be able to start the internal combustion engine and start the vehicle. If you experience problems starting your car, it is important to pay attention to possible starter motor failure symptoms and go to a specialized workshop for diagnosis and repair. Remember that keeping all parts of the ignition system in good condition is essential to guarantee the reliability and safety of your vehicle.
