What are the two main circuits of the starting system?

The starting system consists of two separate circuits, high amperage circuit (150A - 350A) and low amperage circuit (< 20A).

What are the main components of starting system?

What is part of the starter circuit?

A pre-engaged starter has the solenoid mounted on the motor casing. The live terminal on the battery is connected by a heavy lead to a terminal on the solenoid switch which is operated when the ignition switch is turned. The other terminal on the solenoid is connected to a terminal on the starter motor .

What are the types of starter system?

What are the components of starting circuit and its purpose?

Typically, the starter is a large electric motor and stator coil mounted to the bottom (generally to one side) of the vehicle's transmission bell housing where it connects to the engine itself. The starter has gears which mesh with a large flywheel gear on the backside of the engine, which turns the central crankshaft.

Basic Starting System

What is a starter motor circuit?

The starter motor is an electric motor that turns over or "cranks" the engine to start. It consists of a powerful DC (Direct Current) electric motor and the starter solenoid that is attached to the motor (see the picture).

What are the 2 different styles of field windings in starter motors?

The windings on a motor armature can be wound in two ways, known as lap winding and wave winding. Figure 15.10 illustrates the difference between these two methods. Since the wave winding provides most appropriate torque and speed characteristic for a four pole system, starter motors generally use this technique.

How does the starting system work?

To make an engine start it must be turned at some speed, so that it sucks fuel and air into the cylinders , and compresses it. The powerful electric starter motor does the turning. Its shaft carries a small pinion ( gear wheel) which engages with a large gear ring around the rim of the engine flywheel .

What is the operation of starting system?

the purpose of the starting system is to provide the torque needed to achieve the necessary minimum cranking speed. As the starter motor starts to rotate the flywheel, the crankshaft is turned, which then starts piston movement.

What is motor control circuit?

The start and stop action of the motor is determined by the control circuit , which energizes the magnetic motor starter, pulling in or dropping out the armature that then opens or closes the power contacts.

What are the types of starter used for starting DC motor?

There are mainly 3 types of DC motor starters, such as 2 point starter, 3 point starter and 4 point starter. The basic concept behind every DC motor starter is adding external resistance to the armature winding during starting.
