So let’s start with…
What is a Starter Motor?
A starter motor is an integral component of a vehicle’s engine, responsible for initiating the combustion process by turning the engine over. It is essentially an electric motor that uses electrical energy from the battery to rotate the flywheel and crankshaft, which in turn starts the engine.
The starter motor works in conjunction with other components such as the battery, ignition switch, and solenoid to generate enough power to get the engine going. The process begins when you turn your key or press a button to start your car. This action sends an electrical signal to the starter motor via the ignition switch, activating it to engage with the flywheel and crankshaft.
How Does a Starter Motor Work?
↳ The starter motor is a crucial component of your vehicle’s engine, responsible for starting the combustion process that ultimately powers your car. Without a functional starter motor, you won’t be able to start your vehicle and get it on the road. In this section, we will take a closer look at how exactly a starter motor works to provide power to your vehicle’s engine.
↳ Firstly, let’s understand the basic components of a starter motor. It consists of an electric motor, solenoid, gears, and brushes. The electric motor is powered by the battery and is connected to the flywheel or flex plate of the engine. The solenoid acts as an electromagnetic switch that activates the gear mechanism in order to engage with the flywheel and turn it.
↳ When you turn your ignition key or press the start button, an electrical signal is sent from the battery to the solenoid. This causes the solenoid to create a magnetic field which then pulls down its plunger and connects two large terminals together. These terminals are responsible for carrying high amounts of current from the battery directly to the starter motor.
↳ Once these terminals are connected, electricity flows through them into windings within the electric motor creating electromagnetism which gives rise to rotational force (torque).
↳ This torque rotates a small pinion gear attached at one end of an armature shaft inside of a Bendix drive assembly (a clutch-like mechanism) towards flywheel teeth on one side.
↳ As this happens simultaneously, there are two other important things happening. The first one is the engagement of a set of small teeth on one side of the Bendix drive assembly with the large teeth on the starter ring gear attached to the flywheel, which starts turning it. This process is called meshing.
↳ The second thing that happens is the brush contact through which electricity flows from the battery to the commutator rings of an armature shaft and then back out through a set of brushes again providing it energy to rotate continuously when activated by the starter switch.
↳ As soon as this rotation occurs, combustion starts within your engine and your vehicle comes to life. Once you release the ignition key or stop pressing the start button, electricity stops flowing into this circuit, allowing the solenoid plunger to return back to its original position thus opening up contacts inside it which cuts off current flow in half.
↳ This action simultaneously disengages both gear and Bendix drive mechanism from flywheel teeth and causes starter motor rotation to stop completely once again. At that point, all you have left is your running engine and you’re ready for a ride.
↳ In summary, a starter motor works by using electrical energy from the battery to create rotational force through electromagnetism. This force is used to engage with and turn the flywheel, which ultimately starts the engine and allows your vehicle to run. Once the engine is running, the starter motor disengages and is no longer needed until the next time you start your car.
How Much Does a Starter Motor Replacement Cost in Australia?
If you have an older car, you may be able to find a used starter motor for a lower price. The average cost varies between $550 and $1100, but this depends on the factors mentioned below. Before you purchase a second-hand part, make sure that it is compatible with your vehicle.
