How do I pick up the starter? How many binding posts are there on the starter?

1. The one at the beginning of the ignition is connected to the terminal post above the start, and the thick wire of the battery fire wire is connected to a thick terminal post at the starting suction iron. The other is to pick up the route.

2. Generally, there are 4 binding posts, two thick and two thin. The thick one on the right is connected to the battery, and the left one is connected to the iron. Then, the one on the right is the ammeter.

The key switch is connected in parallel, (the ammeter and the key switch are connected in series), the key switch has three binding posts, one of which is connected to the point flow meter.

The second one is the ignition coil during normal driving.

Connected, (the ignition coil has an additional resistance) is connected to the resistor, the third binding post is connected to the right thin wire post of the starter, and the left thin wire post is connected to the starting switch binding post of the ignition coil, that is, it is connected behind the resistor.

A thicker is the power cord of the starter, a thinner is the power supply of the electromagnetic coil, and one should be the negative pole with the iron wire, depending on the specific model, in fact, it can not be installed if it is wrong, as long as it is fit.

The starter, also known as the motor, converts the electrical energy of the battery into mechanical energy and drives the engine flywheel to rotate to realize the start of the engine.

According to the working principle, starters are divided into direct current starters, gasoline starters, compressed air starters, etc. Most of the internal combustion engines are DC-electric starters, which are characterized by their compact structure, simple operation and easy maintenance. The gasoline starter is a small gasoline engine with a clutch and transmission mechanism, which is powerful and less affected by temperature, can start a large internal combustion engine, and is suitable for alpine regions.

There are two types of compressed air starters, one is to drive the compressed air into the cylinder in the working order, and the other is to use an air motor to drive the flywheel. The purpose of compressed air starters is close to that of gasoline starters, and they are usually used to start large internal combustion engines. The DC starter is composed of a DC series motor, a control mechanism and a clutch mechanism.

It is designed to start the engine and requires a lot of torque, so the amount of current to pass through is high, reaching several hundred amperes.

The torque of the DC motor is large at low speed, and the torque gradually decreases when the speed is high, which is very suitable for starter.

The starter adopts a DC series motor, and the rotor and stator parts are wound with relatively thick rectangular cross-section copper wire; The driving mechanism adopts a reduction gear structure; The control mechanism adopts electromagnetic magnetic suction mode.

Generally, there are 4 binding posts, two thick and two thin. The thick one on the right is connected to the battery, and the left one is connected to the iron. Then, the one on the right is connected to the ammeter key switch in parallel, (the ammeter and the key switch are connected in series), the key switch has three binding posts, one is connected with the point flow meter, the second is connected with the ignition coil during normal driving, (the ignition coil has additional resistance) is connected in front of the resistance, the third binding post is connected with the right thin wire post of the starter, and the thin wire post on the left is connected with the starting switch binding post of the ignition coil, that is, it is connected behind the resistor.

That's OK.

The three terminals are: 50 terminals, 30 terminals, and C terminals. The 50 terminal is connected to the ignition switch, the 30 terminal is connected to the positive pole of the battery, and the C terminal is connected to the internal excitation winding of the starter.

The 30 terminals are connected to the power supply via the fuse through the generator, the 50 terminals are connected to the ignition switch via the starting relay, and the C terminal is inside the starter. When the engine is started, turn the ignition switch to the starting position and turn on the starting relay coil circuit. Drive the crankshaft of the engine to rotate so that the piston of the engine reaches the ignition position.

The battery B is connected to the position of the starter electromagnetic switch live wire, the button S is connected to the position of the ignition switch 3 pins, and the screw with the smallest starter is connected (it should be 4 thick), and then the negative pole is struck. There are 3 binding posts on the insulating cover of the electromagnetic switch, which are binding post B (or 30), binding post M (or C) and starting terminal S (or 50).

There are 4 binding posts on the insulating cover of some electromagnetic switches, which are binding post B, terminal M , starting terminal S and ignition binding post R.

Binding post B and binding post M are usually 8mm or 10mm thick copper bolts, and the binding post M with lugs is the terminal terminal of the power supply of the excitation winding of the series motorThe remaining one is the binding post B, which is the live wire binding post of the battery.

The starting terminal S and the ignition binding post R are usually 4mm or 5mm thick iron bolts, and the one with the lugs is the starting terminal S, and the wires on it lead to the starting relay;The remaining binding post is the ignition binding post R, which is connected to the wire with an additional resistor to the ignition coil. The housing of the solenoid switch is also an invisible binding post (31), i.e., an iron.

The starter is generally a single wire, that is, the M terminal and the S terminal are connected to the positive pole of the battery, and the front cover is installed to contact the engine as the negative pole, and some have negative terminal wiring, such as 39MT. As shown below:

Electrician knowledge: how to understand the circuit diagram, starter wiring diagram explanation.

The M terminal and the S terminal are connected to the positive pole of the battery, and the front cover is installed to contact the engine as the negative pole, and some have negative terminal wiring.

Clean the armature and external drive mechanism with gasoline before installation. After cleaning, see if its drive is flexible; When installing, graphite grease should be applied between the friction plates of the friction clutch, and the thread filament part should be coated with organic oil; The starter is installed on the engine, and the distance between the end face of the driving gear and the plane of the flywheel should be 3-5 mm to ensure the correct meshing of the gear.

The starter is composed of a single wire, that is, the M terminal and the S terminal are connected to the positive pole of the battery, and the front cover is installed to contact the engine as the negative pole, and some have negative terminal wiring, such as 39MT. As shown below:

Starter, also known as motor, is powered by a DC motor, which transmits power to the flywheel ring through the starter gear, and drives the flywheel and crankshaft to rotate and start the engine.

The starter has a small wire, and what is the same.

Those who have not removed the starter will definitely not know which terminal of the starter is positive and which is negative. Now I'll teach you how to look at the terminal diagram of the starter. If you don't know, let's take a look.

The starter is called a motor, which converts the electrical energy of the battery into mechanical energy and drives the engine flywheel to rotate to realize the start of the engine.

The starter has three to four binding posts, and the three columns include the motor input terminal, the control signal terminal, and the power input terminal. The four columns include the motor input terminal, the control signal terminal, the power supply input terminal, and the starting energy enhancement terminal.

Here's how to connect:

The small binding post is the control signal end, and the motor input end is connected to the control signal, and the resistance level of the universal meter is used to measure. The rest is the power input end, the four columns have a starting energy strengthening end, it is the same size as the control signal end, easy to distinguish, and the starter shell is connected to the signal control end, using the resistance of the multimeter measurement.

Friend, the three terminals of the starter are the positive terminal, the negative terminal, and the starting relay terminal.

This kind of switch is generally two switch feet, the other yellow light is the light foot, the three feet together can be turned on the light, this is the alternating current without positive and negative poles, if there are only two wires, that is the middle heel of the yellow light first connected together, and then connected to another foot, the switch is turned on after the light is also lit together.

The principle of this switch is a phase wire (live wire) and a neutral line into the indicator light of the switch, and the other is the control line, to the control line power, the indicator light will not be on, turn off the control line power, the indicator light is always on.

It is the most basic switch with power signal light indication, the earliest light switch is the same principle, generally there are signs next to the terminal block behind this switch.

It is also easy to know the position of its signal light with a multimeter, no matter how you turn the switch, there is resistance on one side of the signal light, but there is no on the other side.
