How to connect the vibration motor with a relay, and how to connect the vibration motor only to the

If it is a cold start, it may be that there is a problem with carbon collection and speed signal in the cylinder. If it is a hot start, it may be a problem with the water temperature sensor, or a problem with the vehicle emission related system, such as activated carbon tank blockage, etc.

The ignition system does not ignite, and the ignition timing is inaccurate; The injector does not work or works poorly, the cold start injector does not inject, the injection pressure is too low, the injector is blocked or leaking, and the injection control signal is poor; The fuel pump is not working; Enter.

Three-phase electricity. 1. Main circuit:

There has to be a barrier switch, and the three live wires are connected to the contactor 1, 3, 5--2, 4, and 6 respectively.

2. The ground wire is directly connected without passing through the switch.

3. Control circuit:

Optimistic about contactor coil voltage:

A, 220V, one end is connected to a fire from the knife switch and read the line, and one end is grounded.

B, 380V, both ends are connected to the two live wires from the knife switch switch.

In this way, when the knife height is closed, the brake will be activated, and the knife brake will be stopped when the knife brake is disconnected.

First: After the vibrating motor is turned on, the vibrating motor cannot be started.

Technicians should check these three aspects of the vibrating motor: 1. Whether the power supply is out of phase; 2. Whether the motor is out of phase; 3. Whether the protective cover is damaged and rubs the eccentric block;

The second type: after the vibration motor is turned on, there is an emergency situation such as motor noise and heating, at this time, the vibration motor maintenance personnel should check

1. Whether the roughness of the contact surface between the vibrating machinery and the motor foot meets the installation requirements;

2. Whether the anchor spiral is tight;

3. Whether the vibration acceleration of the host meets the requirements of use;

The third type: after the vibration motor adjusts the eccentric block, the maintenance personnel of the vibration motor with abnormal amplitude change should check whether the eccentric blocks at both ends of the rotating shaft of the vibration motor are symmetrically adjusted;

Fourth: in the vibration equipment where two vibrating motors work at the same time, when its phase does not meet the requirements, the maintenance personnel of the vibrating motor must adjust the phase sequence of a single machine, and do not adjust the phase sequence of the total power supply of the two vibrating motors.

Inventory of the causes that cause motor vibration.

When installed vertically and at any angle, it should be ensured that the double bearing end is installed on the lower side, that is, the non-outlet box end of the motor is installed on the lower side, and YZO-16-6 will be on the line, such as the safety point is turned opposite to the YZO-20-6 motor.

The wiring is the same, the principle of the vibration motor is to add an eccentric device at the output end of the motor shaft, and the motor will vibrate after turning away.

There is no "vibration motor" in the world, and if an eccentric weight is attached to the motor shaft, it vibrates.

You have to connect the weight of the non-eccentric chakra into a "vibrating one", and if you remove the three phases from one phase, it will vibrate, but it will also smoke. Three-phase six-wire, according to the delta method, one of the coils is reversed, it will also vibrate, but it will also smoke.

The wiring is the same.

The vibration is eccentric.

After power-on, the vibrating motor does not rotate, but there is no abnormal sound, and there is no peculiar smell and smoke, and the possible reasons for the failure are as follows: The power supply of the vibrating motor is not connected (at least two phases are not connected); What is the reason why the vibrating motor does not rotate after power-on? After power-on, the vibrating motor does not rotate, but there is no abnormal noise, and there is no peculiar smell and smoke

The power supply of the vibrating motor is not connected (at least two phases are not connected); fuse blowing (at least two-phase blowing); The overcurrent relay of the vibrating motor is adjusted too small; The control device is incorrectly wired. Troubleshooting method: Check whether there is a break point at the power circuit switch, fuse and junction box of the vibrating motor, and repair it; Check the fuse model, the cause of the fuse, and replace the fuse; Adjust the setting value of the relay to cooperate with the motor; Correct the wiring of the vibrating motor.

Check whether the power supply of the motor is normal, whether the switch is normal, whether the contactor is normal, and whether the coil and insulation resistance of the motor are normal.

There is no fixed formula for this, depending on the nameplate of the specific product, maybe the speed can be adjusted, and the two wiring can be switched.

In order to better protect the safety of personnel and equipment, electrical I equipment is equipped with various control and protection circuits. Taking the vibration motor as an example, in addition to the necessary devices such as start and stop buttons and AC contactors, it is also equipped with circuit breakers, thermal relays and other protection devices.

From the analysis of the control principle, there are three reasons why the motor starts directly without pressing the button

1. The start button is stuck and does not return, and the button is in the connected state;

2. The contacts of the AC contactor are sticky and in a closed state for a long time;

3. The failure of the control loop causes the contactor to be directly engaged after power.

There are currently two types of vibration motors for mobile phones, one is DC brushed and the other is DC brushless motor.

The principle of vibration is an eccentric weight. The old-fashioned cylindrical vibration motor is generally DC brushed, and a simple transistor + freewheeling diode is generally used.

Drive on the line (the same as the relay),But if you need to make a better vibration effect,You need to design a circuit that can regulate the speed and brake,Then you have to use some brains.,Personally, I think the vibration effect of Nokia is good.。

Brushless ones are generally flat, like silver coins. The drive circuit is mostly a special integrated chip, which can achieve better vibration effects (braking, commutation, speed regulation). Recommend one: A1442.

The vibration of the mobile phone is actually caused by the centrifugal force of the DC motor driving the eccentric wheel, and the simple drive can be driven with a triode.

An oscillation circuit is made with a transistor. Turn direct current into alternating current and search a lot of circuit diagrams on the Internet.

It is necessary to use the triangle connection, because in the winding coil that bears the same voltage and the same wire diameter, the star connection is 3 times (times) less than the triangle connection, and the power is 3 times smaller. The connection method of the finished motor has been fixed to withstand the voltage of 380V, which is generally not suitable for change. Only when the three-phase voltage level is different from the normal 380V, the connection method will be changed, such as the three-phase voltage 220V level, the original three-phase voltage 380V star connection can be changed to the triangle connection; For example, when the three-phase voltage is 660V, the original three-phase voltage 380V triangle connection can be changed to the star connection, and its power remains unchanged.

Generally, the low-power motor is a star-shaped connection, and the high-power is a triangle connection. Under the rated voltage, the motor with a triangle connection should be used, if it is changed to a star connection, it is a step-down operation, the motor power is reduced, and the starting current is also reduced. Under the rated voltage, the motor with a star connection should be used, if it is changed to a triangle connection, it is an overpressure operation and is not allowed.

The current of the high-power motor (delta connection) is very large, in order to reduce the impact of the starting current on the line, the step-down start is generally adopted, and the original delta connection operation is changed to star connection start is one of the methods, and the star connection is converted back to the triangle connection operation after starting.
