MAINTENANCE OF THE STARTER SYSTEM ON THE 1992 MAZDA MR CAR

In the final project report. Teknik Mesin DIII. Faculty of Engineering. Bogor Academy of Technology Automotive technology is one of the fields whose technological developments always keep up with the times and demands. The starter system functions to make the engine start process easier. An electrical system that works on the starter motor to convert electrical energy from the current source (battery) into mechanical energy (rotary). The DC series motors consume direct current electric power with a generated field coil to form a magnetic field connected in series with an almature coil. The current that flows on the conductors in the motor assembly causes an electromotive force due to the occurrence of the Lorentz force so that it produces rotation and torque with a magnitude of 2249.86 Nm. From the resistance that exists in the starter motor, an efficiency of 87.2% is obtained from the 24v 4.5kw motor. The rotation produced by the motor is transmitted by reducing the pinion gear with the ring gear on the flywheel on the top of the gear calculation. The gear ratio is determined to reduce the rotation and increase the torque with the reduction of the planetary gears.
