What precautions should be taken when starting the engine with a starter motor?

What precautions should be taken when starting the engine with a starter motor?
Time limit: Each startup time should not exceed 5 seconds. If the first startup fails, a second attempt should be made at least 15 seconds apart. Continuous starting can cause the starter to overheat, damage the insulation layer of the coil, and even burn out the motor.

The core structure of the starter motor

The core structure of the starter motor
Containing components such as armature, commutator, magnetic poles, and electric brushes, it is the core of energy conversion. After being powered on, the armature rotates under force in the magnetic field, generating mechanical energy.

What is the working voltage of the starter motor?

24V: The standard specification for medium and heavy-duty commercial vehicles, construction machinery, and large agricultural machinery, suitable for large displacement diesel engines such as heavy-duty trucks, buses, excavators, harvesters, etc., matched with a vehicle 24V dual battery series power supply system to meet high torque starting requirements.

Working principle of starter motor

The ignition switch is turned on to the starting gear, and a small current triggers the attraction/holding coil of the electromagnetic switch. The armature drives the shift fork to push the driving gear out and mesh with the flywheel ring gear.
