The central laminated iron core is composed of several layers of thin metal sheets, and copper wires are wound around and between the iron sheets in a predetermined manner.The entire assembly is then laminated with the shaft, metal sheet and copper wire and cured in a furnace.The lamination ensures that there is no power shortage between the three components.
The lamination and the copper wire are separated by thin paper and then kept intact through the lamination process, using an appropriate rope.
When a current is applied to the copper winding, a magnetic field is generated.The coil used is called the armature.
Then put the entire laminated armature shaft into the starter motor housing.Multiple sets of copper wire loops are fixed on the shell of the starting motor, called the stator.The armature rotates inside the stator through bushings and bearings.The gap between the two can be as small as one millimeter.
According to the wiring diagram of the starting motor, the current passes through the stator and armature at the same time.The Tractor starter Generate a fixed magnetic field, which can be compared to the force of a strong permanent magnet.
The armature mounted on the bearing and bushing will induce a magnetic field from the current inside it.The magnetic field will react to the magnetic field of the stator and produce a movement in one direction according to Fleming's left-hand rule.
Many other components are used in the starter motor structure, namely screws, springs, end plates, solenoids, commutator brushes, and drive gears.These additional components will complement the two parts of the starter, namely the armature and Tractor starter.
