starter (Starter) called motor which generates power by a DC motor, the power to be transmitted through the starting flywheel ring gear, driven by the flywheel, the rotation of the crankshaft to start the engine.
1. Introduction starter
into the starter according to the working principle of the DC starter, the starter gas, compressed air, etc. starter . Most currently used in an internal combustion engine is a DC starter, which is characterized by compact structure, easy to operate and easy to maintain. Gasoline Gasoline Engines starter is a small transmission mechanism having a clutch, the power is large and the temperature is less affected, large internal combustion engine can be started, and is suitable for alpine zone. Compressed air starter currently divided into two categories, one is a compressed air into the cylinder in accordance with the sequence of operation is to use air motor flywheel. The use of compressed air starter starter close to gasoline, is generally larger for starting the internal combustion engine.
motivated by the DC series wound DC motor is composed, the clutch mechanism and the steering mechanism. It is designed to start the engine, you need a strong torque, and therefore a large amount of current to be passed, several hundredampere.
Large DC motor torque at low speed, the torque is gradually reduced at high speeds, it is suitable to start with a motive.
starter series wound DC motor, the stator and rotor parts are of rectangular cross-section with a relatively thick copper wire; a drive mechanism using the reduction gear structure; electromagnetic actuating magnet mode.
2. Starter maintenance
In the process of the starter in starting the engine, from the introduction of 300 ~ 400 Ah battery power, the battery in order to prevent the phenomenon appeared stream or damaged, starting time should not exceed 5s. Winter prone to the phenomenon of start-up difficulties, many times starting when each start time not too long, each time starting should also leave appropriate intervals.
3. Starter troubleshooting
1, the battery power is low and no electricity or, So there can not rotate or rotates slowly starter failure.
2, the starter thread loose or fall off, a switch or switch failure adsorption.
3, the brush surface or brush wear is not correct, weak spring, so that the rectifier poor contact.
4, the exciting coil and armature coil short circuit.
5, rectifier offset, mica projection, resulting in poor contact brushes and the rectifier.
