Common Types of Starters?

Starters convert the electrical energy from the battery into mechanical energy, driving the engine flywheel to rotate and enabling engine startup. Before an engine can operate under its own power, it must be rotated by an external force. The process of transitioning the engine from a stationary state to self-sustained operation with the help of external force is called engine starting. There are four common types of starters. 1. Conventional Starter: The drive gear rotates at the same speed as the armature, with no reduction mechanism. 2. Externally Meshed Reduction Starter: Reduces armature speed through reduction gears, increasing torque. 3. Planetary Gear Starter: Reduces armature speed via a planetary gear transmission mechanism, enhancing driving torque. 4. Planetary Reduction-Permanent Magnet (PS) Starter: This type uses permanent magnets to generate a magnetic field and employs a drive lever to engage or disengage the drive gear with the flywheel ring gear.
I've always paid attention to the starter when driving. The most common types include: DC starters are the most basic type, powered directly by the battery—they're loud during startup but quite reliable. Permanent magnet starters are also widely used nowadays, featuring permanent magnets inside, making them lighter and more energy-efficient. Gear reduction starters are common in high-power vehicles like SUVs, as they amplify torque for easier starts. Planetary gear starters are similar but more compact, ideal for small cars to save space. Recently, the DC starter in my old car suddenly seized, causing a breakdown on the road. Fortunately, a neighbor helped check and found it was due to aging wiring. Remember to have technicians test the voltage during regular maintenance to avoid cold-start difficulties—it's crucial for safe travel, and a little time spent can prevent major issues.
As a car enthusiast, I'm obsessed with studying parts. Common starter types include the DC type—simple in structure and standard in older cars; the permanent magnet type—reduces coil loss for greater durability; the gear reduction type—uses gear sets to enhance torque, super practical; the planetary gear type is more precise, with quick starts and low noise; and the Integrated Starter Generator (ISG), commonly found in hybrids like the Toyota Prius, enabling start-stop functions for fuel efficiency and eco-friendliness. I've seen someone modify a gear reduction type, only to blow a fuse due to unstable current, so don’t tamper with the circuit recklessly. Design differences mainly stem from battery efficiency and space constraints—just choose what suits you. Beginners can start with the standard DC type and maintain it diligently to extend its lifespan.
