Starters Introduction

Starters are engineered to provide the torque necessary for dependable starting in today’s vehicles. Every unit is 100% NEW (not remanufactured) and made with proprietary components and processes to ensure maximum life and performance.
Engineered to deliver torque output for starting power that meets or exceeds the original equipment on your vehicle
Every unit is built with 100% NEW components that are designed to meet the highest quality standards
Every unit is triple tested (component, subassembly and end of line) to ensure quality and performance


Starter Function

Combustion engines in motor vehicles need starting assistance in order to runStarter independently. The starter is one of the most important components of the starter system. As well as the starter, the system includes switching devices and control units, cables and the starter battery.
To reach the speed required for the engine to run independently with as small as possible a starter motor, the significantly higher speed of the starter is adapted to the engine speed by means of a ratio between starter pinion and engine ring gear.
The starter comprises the following assemblies:
  • Electric motor
  • Engagement system
  • Freewheel
  • Pinion and possibly countershaft transmission
    During starting, the engagement relay engages the starter pinion in the gear ring. The starter motor is linked to the starter pinion either directly or via a countershaft transmission which sets back the speed of the DC motor. The starter pinion drives the combustion engine via the motor gear ring until it is running independently.
    Once started, the combustion engine can accelerate quickly to high speeds. Even after just a few power strokes, the engine speed is higher than it was during starting. To protect the starter against speeds that are too high and thus against mechanical damage, the starter pinion is fitted with a freewheel which isolates power transmission between pinion and armature. When the ignition key is released, the starter relay drops out and the disengagement spring releases the pinion from the gear ring.

    How do the starter works?

    The starter motor is an electric motor that turns over or "cranks" the engine to start. It consists of a powerful DC (Direct Current) electric motor and the starter solenoid that is attached to the motor . In most cars, a starter motor is bolted to the engine or transmission, motor works inside below.
    The starter motor is powered by the car's main 12-volt battery. To turn over the engine, the starter motor requires a very high electric current, which means the battery has to have sufficient power. If the battery is discharged, the lights in a car might come on, but it won't be enough power (current) to turn over the starter motor.

    The properties of the starter

    Starters for passenger cars must be lightweight, small, powerful and economical. The latest models impress with their lightweight, compact design, as lower weight reduces both fuel consumption and emissions. Furthermore, small starters create more room for design during vehicle development.
    The aim of future development work will continue to be to reduce frame size and weight whilst maintaining or increasing power and performance.
    Your starter is really an electric motor. It engages when you turn the ignition to “run” and turns the engine over allowing it to suck in air. On the engine, a flexplate or flywheel, with a ring gear around the edge, is attached to the end of the crankshaft. On the starter, there’s a gear designed to fit into the grooves of the ring gear (the starter gear is called a pinion gear).
    When you turn the ignition switch, the starter motor is energized, and the electromagnet inside the body engages. This pushes out a rod to which the pinion gear is attached. The gear meets the flywheel, and the starter turns. This spins the engine over, sucking in air (as well as fuel). At the same time, electricity is sent through the spark plug wires to the plugs, igniting the fuel in the combustion chamber.
    As the engine turns over, the starter disengages, and the electromagnet stops. The rod retracts into the starter once more, taking the pinion gear out of contact with the flywheel and preventing damage. If the pinion gear remained in contact with the flywheel, it’s possible that the engine would spin the starter too fast, causing damage to it.
