Bajaj Pulsar Starter Motor

The starter motor in a Bajaj Pulsar, also referred to as a self-starter, is an essential electric component responsible for initiating the engine's operation. When you press the starter button, this motor engages with the engine's flywheel, spinning the crankshaft and starting the combustion process.

Key Features

  • Electric Starter: The Pulsar utilizes an electric starter motor, powered by the bike's 12V DC battery.

  • High Torque Output: The starter motor is designed for high torque at low speeds to effectively turn the engine over, especially during cold starts or under load.

  • Automatic Engagement/Disengagement: A small gear on the starter motor (pinion) engages with a large gear on the engine's flywheel during starting. As soon as the engine starts and reaches a self-sustaining speed, the starter motor automatically disengages to prevent damage and conserve battery life.

  • Durable Construction: Built with materials like steel, aluminum, and copper, the starter motor is designed for durability and longevity, capable of withstanding the demands of frequent starts.

Components and Function

  • Armature: The rotating part of the motor that generates the torque needed to turn the engine.

  • Solenoid: An electromagnet that acts as a switch. When activated by the starter button, it connects the battery to the starter motor and simultaneously pushes the pinion gear forward to engage with the flywheel.

  • Pinion Gear: A small gear attached to the starter motor shaft. It engages with the flywheel's ring gear to crank the engine.

  • Flywheel: A heavy disk connected to the engine's crankshaft. The starter motor's pinion engages with the flywheel's ring gear to rotate the engine.

  • Starter Clutch/Overrunning Clutch: This mechanism ensures the starter motor disengages from the flywheel once the engine starts, preventing it from being over-spun and damaged.
