2013 honda accord starter motor

Structure and Working Principle1213

• Structure: The starter motor of the 2013 Honda Accord is usually a permanent - magnet DC motor, mainly composed of an armature, permanent magnets, and brushes. Without the need for exciting coils, the permanent - magnet structure reduces the internal power consumption of the winding, making the motor more efficient and durable.


• Working Principle: When the ignition switch is turned on, the current from the battery flows through the ammeter and the ignition switch to the starting relay. The coil of the starting relay generates a magnetic field, magnetizing the iron core and attracting the contact arm to close, thus turning on the electromagnetic coil circuit. Meanwhile, the current circuits of the pull - in coil and the hold - in coil are connected. The pull - in coil has a small resistance and a large current, which is connected in series with the motor circuit, making the motor rotate slowly so that the pinion can mesh with the flywheel. The combined magnetic flux of the two coils moves the movable iron core forward, driving the shift fork to make the drive gear of the starter motor mesh with the flywheel of the engine, and then driving the engine to start.

Features13

• High - efficiency and Long - lasting: Due to the adoption of a permanent - magnet structure, there is no power consumption of the exciting coil. Therefore, the starter motor has high efficiency and a long service life, which can meet the long - term use requirements of the vehicle.


• Excellent Torque Characteristics: The motor has the characteristic of high torque at low speed when the load increases, and low torque at high speed when the load decreases. This performance can well meet the requirement that the engine needs a large torque in a short time during starting.

Installation Position and Maintenance26

• Installation Position: The starter motor of the 2013 Honda Accord is generally located in the engine compartment, near the engine side, usually under the intake manifold. It is surrounded by wires and pipelines, and can be found by carefully checking the engine compartment.


• Maintenance: Although the starter motor is relatively durable, improper use may affect its service life. For example, frequent start - stop operations will shorten its service life. Regular inspection of the starter motor is necessary, including checking the wear and tear of the armature and the contact condition of the brushes. At the same time, ensure that the power supply circuit is well - connected to avoid problems such as poor contact affecting the normal operation of the starter motor.
