STARTER MOTOR OF A VEHICLE FOR IMPROVING STARTING EFFICIENCY BY FORCIBLY COOLING INTERNAL TEMPERATURE OF THE STARTER MOTOR IN ROTATING A FAN

摘要

PURPOSE: A starter motor of a vehicle is provided to flow and discharge external air while rotating a fan in starting by forming an air inlet and an air outlet at the bracket of the starter motor and mounting the fan in the rear end of the armature assembly of the starter motor. CONSTITUTION: A starter motor(20) of a vehicle starts an engine by supplying rotational force to the engine with electric energy of a battery. An air inlet(15) and an air outlet(16) are formed at the side of a bracket surrounding the starter motor, and a fan(10) is mounted in the rear end of an armature assembly(3). The fan is rotated in turning the armature assembly by a magnet inducing magnetic force in starting to flow in and discharge external air and to forcibly cool the starter motor. The fan is integrally formed with a ring, and to an assembling member is welded into the fan to mount the fan in the rear end of the armature assembly.
