Auto part electric starter

Types of auto part electric starters

The auto part electric starter is basically a motor that cranks the engine so that it can start. This starter motor gets power from the battery. When a driver turns the ignition switch, electrical contacts close. This action signals the battery to send power to the starter motor and crank the engine.

There are two main types of starter motors:

• Brush starter motors: They use a series of wound copper coils called an armature and a commutator to spin the motor's output shaft. They have a simple design, are inexpensive to manufacture, and are widely used in many applications. However, they require regular maintenance, like replacing carbon brushes and cleaning dust.
• Brushless starter motors: These have a more complex design with wound coils in the stator and permanent magnets in the rotor. When electricity flows into the coils, it creates a magnetic field that causes the rotor to spin. Brushless motors don't have brushes or commutators, so they require little maintenance and last longer. They're more efficient and generate more torque, which is great for cranking engines.

The auto part electric starter can also be classified into two main categories:

• Starter motor: This is the most common type and is found in many gasoline and diesel engines. It uses an electric motor to crank the engine. The battery supplies power to the starter motor when the ignition switch is turned.
• Starter-generator: This type combines the functions of a starter motor and an electric generator. It is commonly used in hybrid and electric vehicles. The battery or high-voltage battery pack provides power to the starter-generator, which cranks the engine and generates electricity while driving.

Other types of electric starters include mini starters, high-torque starters, permanent magnetic starters, and reduction gear starters. Mini starters are small, lightweight, and suitable for applications where space is limited. High-torque starters produce high torque, making them suitable for heavy-duty applications. Permanent magnetic starters use permanent magnets instead of windings to generate a magnetic field, eliminating the need for field windings. Reduction gear starters have a set of gears that reduce the motor's speed and increase its torque to crank the engine more effectively.

Specification & Maintenance of Auto Part Electric Starter

The specification of an auto part electric starter is often a complex and intricate one. This is because of the various components that work together to ensure that the vehicle's engine is started. Here are some of the specifications to look out for:

• Voltage:

  Electric starters are available in different voltages depending on the car's electrical system. For instance, a 12-volt starter is often used in most conventional cars, while a 24-volt starter is used in heavy-duty and large vehicles.

• Current draw:

  The starter motor draws a high current from the battery when starting an engine. The current draw can range from 100 to 1000 amps depending on the voltage and size of the starter.

• Gear ratio:

  The starter motor often uses a pinion gear that matches the flywheel or flexplate. This gear is responsible for ensuring proper engagement and disengagement.

• Solenoid type:

  The solenoid is often used to push a switch closed and is available in two types: the in-line and the mounted variety. The type of solenoid determines how the starter motor is controlled from the ignition switch.

• Windings:

  Windings are important components of the starter as they help produce the magnetic field required to turn the engine over. They are often made from copper or aluminum wire and come in different sizes and configurations depending on the starter design.

• Housing material:

  The starter motor is housed in a case that is made from a variety of materials. The materials include aluminum, plastic, and steel. Each of these materials has its unique properties that make them suitable for housing the starter motor.

Maintenance of electric starters is important to ensure they function properly. Here are some maintenance tips:

• Regular inspection: The starter, battery, and charging system should be inspected regularly to ensure they are in good condition. The cables and terminals should also be checked for any sign of damage.
• Keep it clean: The starter and surrounding area should be kept clean and free of debris, dirt, and moisture. This is important as accumulated moisture can lead to corrosion, which affects the starter's performance.
• Use it correctly: The starter should only be used for starting the engine. Avoid cranking the engine for long or repeatedly cranking it, as this can damage the starter over time.
• Replace worn parts: Any worn or damaged parts of the starter should be replaced promptly to prevent further damage and ensure reliable starting. The warning signs to look out for include slow cranking, grinding noise, and clicking sound.
• Professional service: Take the vehicle to a qualified mechanic for periodic maintenance and service. This is important as the professionals have the right tools and knowledge to maintain and repair the starters effectively.

Q and A

Q1. How to know the starter motor is bad?

A1. There are several signs that the starter motor may be failing. First, there may be a delay or no response when turning the ignition key. The engine may crank slowly, or there may be a clicking sound. In some cases, the starter may crank intermittently, or the engine may crank, but it won't start. If the starter keeps running after the engine has started, or there is a burning smell coming from the starter, it's time to replace it. Multiple attempts to start the vehicle can also indicate a starter issue.

Q2. What are the different types of starters?

A2. There are several types of starters available. The most common are manual and automatic starters. An automatic starter allows the driver to start the engine with the push of a button, while a manual starter requires a lever or button to be engaged by the driver. Keyless starters are becoming more popular, as well as remote starters that allow the engine to be started from inside the vehicle or from a remote fob. Coil-starting and electric starters are also available.

Q3. What is the role of the starter solenoid?

A3. The starter solenoid is a critical component of the starter system. Its main role is to act as a switch that connects the battery to the starter motor. When the ignition key is turned to the start position, the solenoid receives a small electrical signal from the ignition switch. This signal activates the solenoid, closing the circuit and sending a large current from the battery to the starter motor. This allows the starter motor to crank the engine without requiring the ignition key to be held in the start position.

Q4. How long does a starter last?

A4. Starters are designed to last for thousands of starts - typically 100,000 to 200,000 starts, depending on the model and usage. With average use of 20 starts per day, a starter can last for 10 to 30 years. However, factors such as short trips, extreme temperatures, and heavy loads can cause the starter to wear out faster. Signs of a failing starter should be addressed promptly to avoid getting stranded.
