Description
1. Core attributes
Part Name: Starter Motor Assembly
Original factory part number: 36100-25020
Brand: Hyundai Genuine Parts or Hyundai Mobis
Type: Original Equipment Manufacturer (OEM)
Applicable vehicle models: Mainly applicable to the 5th generation (NF) and 6th generation (YF) Sonata (produced from 2004 to 2012). The specific matching will be finally determined based on the engine model and VIN code.
2. Core functions
This component is the core actuator for starting the system. Its core function is to convert the electrical energy of the battery into mechanical energy. It works through the electromagnetic switch (pull-in bag), driving the pinion forward to mesh with the gear ring of the engine flywheel, then driving the crankshaft to rotate, reaching the required speed for engine start-up, and completing the ignition and start-up.
3. Technical Features and Design
Pre-meshing design: The standard design for modern starter motors. The electromagnetic switch first pushes the fork to fully mesh the drive gear with the flywheel ring gear, and then connects the main circuit to make the armature rotate at high speed. This design avoids gear impact and tooth breakage, ensuring smoother operation, lower noise and extremely high reliability.
High-performance electromagnetic switch: The electromagnetic switch (pull-up package) integrated into the motor body serves as the control center. The magnetic force generated by its internal coil is responsible for driving the gear meshing and connecting the main contacts with high current, which operates quickly and reliably.
Durable materials
Drive gear: Made of high-strength alloy steel and treated with carburizing and quenching, it is extremely wear-resistant.
Armature assembly: It uses high-quality silicon steel sheets and pure copper wire windings, featuring high conductivity and low heat generation.
Bearing system: Powder metallurgy bushings or rolling bearings are adopted, which can withstand frequent high-load impacts and have a long service life.
4. Quality and compatibility
Original factory quality guarantee: This part number indicates that it is manufactured by an officially certified supplier of the Hyundai-Kia Automotive Group (usually Hyundai Mobis). It fully complies with the engineering design specifications, performance standards and durability requirements of modern automobiles, and its quality is exactly the same as the original components installed when the vehicle leaves the factory.
Perfect matching: Its physical installation dimensions, gear parameters (module, number of teeth), electrical interfaces (plug model, pin definition), and performance outputs (power, torque, speed) are all perfectly matched with the corresponding engine ECU program, battery capacity, and flywheel. It ensures plug-and-play functionality, avoiding compatibility risks or potential system failures.
Performance consistency: It can precisely reproduce the initial start-up experience of the vehicle - fast start-up speed, powerful sound and reliability in one start.
5. Applicable vehicle models (Examples)
Crucial: The applicability of part numbers strictly depends on the vehicle's VIN code. The following list is only a common example and not a complete one. Final confirmation must be made through the VIN code.
This part is generally applicable to modern Sonata models equipped with 2.0L or 2.4L Theta series engines, such as:
The 5th generation Sonata (NF) : 2004-2009 models
The 6th generation Sonata (YF) : Model year 2009-2012
