Starter Motor Function and Base Operations

Starter Motor Function and Base Operations
Starter motor function
Function converts electrical energy into mechanical energy from the battery so that the shaft can be turned shaky start for starting the engine.....


Basic operating a motor starter

the permanent magnet, the magnetic force moving grain from north pole to south pole. Flows from the battery flows to the armature through the ring side, to form the veins of the magnetic force on the armature. Veins occur when the magnetic force on the armature, this will lead to veins of the magnetic force of permanent magnet will be deflected or refracted and then move the armature to rotate.

When the armature has a rotating 180 degrees, this will Cause the current in the armature movement is also rates changed (this is Because the sides of the ring action), the direction of movement of the magnetic force on the anchor tendon is changed. If the previous direction of movement of the armature magnetic force black veins BUT once Haunted is clockwise 180 degree movement, muscle movement of the magnetic force on the armature of black has turned clockwise versus this incident take place in accordance with the law left hand. With the change of direction of tendon force in the armature will enable the armature rotates 360 degrees while continuing to flow from the battery supplied with the anchor

The law left hand

  
When a conductor on the handheld with
 left hand, the interpretation says the thumb is the direction of current flow (+), while the four fingers grasping the conductor shows the movement of grain is the magnetic force on the conductor.


           The motor starter used in the actual vehicle, it does not use permanent magnets as described in the evidence before it. BUT it is the shoes and loop to act as an electromagnetic field. Electricity is supplied from the battery supplies power to get enough fiber magnetic force.

  Basic Components Starter Motor

Basic components of the starter motor is as below:

 Anchor
The armature is the number of curves of conductor wrapped around the iron core serves to create a deflection or refraction of the magnetic force on the footwear vein poles. This will cause the armature rotates. The more the number of arc armature and the electric current that flows through the armature, the higher the torque generated by the starter motor. Every end of the arc armature mounted on the sides called a commutator ring to receive a stream of carbon brushes.
Commutator.
Commutator is a ring of copper that cut so as not to touch each other. Every piece is connected to the end of the curve of the armature, and it is connected to the carbon brush to receive current from the battery. Function to enable the arc current in the armature receiving switch direction, so that the veins of the magnetic force on the pole shoes can be deflected continuously. With the armature will continue to rotate 360 degrees while still in the supply of current provisions on the starter motor.

Field and the polar loop shoe
The loop field is assembled conductor wrapped around the pole shoes, which shoes tied to the pole is in the home page so that the starter motor is not moving. Current will flow on to the field coil pole shoe to the electromagnetic. The more current in the coil field, the more powerful elaktromagnet the pole shoe, the higher the torque generated by the starter motor.

Pinion drive
Pinion drive is a small gear mounted on the armature shaft end, for the purpose of driving the ring gear on the flywheel can be rotated so that the engine will moved.ratio round of the drive pinion with the flywheel ring gear is 15:1, and sometimes if the vehicle is great rate can achieve a ratio of 20:1.

Field coil connections on the starter motor

 Field coil in parallel connection

Starter motor that uses field coil connection method of this type uses a pair of parallel poles, and it is only used in small type starter motor. The conductor is connected from the source to be separated into two, one around the first shoe and the other around the second shoe, and the second conductor is connected to the armature and grounded. When the current flowed to the coil, the electromagnetic polarity also occurs in shoes to generate a magnetic field. This series of connections to reduce the resistance of the conductor, thus allowing current to flow more to produce a strong magnetic field pole shoes.

Field coil in series connection

 

Field coil in series connection, the conductor is wound on the pole shoe of the shoe first, second, third and fourth in series. It is to the north and south poles producing more, when current is passed through the conductor. Flows from the battery to go to the four fields in a series of loops before going into the last anchor to the ground. This will place the two poles north and south poles. When the number of north and south poles, the more muscle even more powerful magnetic force. With the motor torque increases.

Field coil in series connection and parallel

Connection type field loop series / parallel conductors wound around the pole shoes in devide the two. The conductor is wound on the shoes first and second series, while the other conductors in the wind in the third and fourth shoe in the series as well, and then connected to the armature and then grounded. Both loops groups (one and two-shoes, sandals and a group of three or four other groups) It is in parallel with each other. By the field coil circuit is said to be series and parallel. ie increasing the number of poles and also reduce the resistance. With a combination of both these advantages, the strength of the magnetic force better nerves and also increases the efficiency of the motor starter.

Field coil in series connection and distorted

Connection type parallel loops and stray field, the conductor of the divide into two also rates. The conductor is wound on the shoes of one, two and three in the series and then connected to the armature to an earthed. A conductor is connected to the shoe to four and Further grounded. The position of the loop field in the fourth shoes are parallel or diverge with the conductor or the coil on the shoes of one, two and four pole. Footwear veins of the magnetic force is said to have more power than others Because its field coil is connected DIRECTLY from the source to the ground without going through a lot of resistance. With these shoes on the fourth side to produce a high thrust power of the other shoes, and was Able to produce high torque at start turning the engine.
