Common faults of drum motors, what is the matter with the drum motor motor not rotating the drum

Front-loading washing machines have a certain number in society. The judgment and maintenance of common faults are as follows.

1.Drain water while entering the water.

Check first whether the drainage pipe is placed too low (not less than; Then check whether the drain nozzle is inserted into the floor drain. If yes, adjust the position of the drain pipe (80cm to 100cm). If not, see if the water level is too high to submerge the glass.

No, adjust the water level switch or solenoid valve or drain pump plug line. If the water is not only overflowing from the distributor box, check whether the pressure switch, hose, and gas collection valve hose are leaking? Whether there are foreign objects in the gas collector valve and pressure switch.

If the drain pump drains water when the water is ingress, it is the washing machine to protect the water level switch, and it can be replaced.

2.No water.

If the washing machine does not enter the water, first check whether the micro-delay is self-locking and whether the door lock indicator light is on. If it is good, you need to press the door lock light to turn on, then you need to reinstall the micro delay and adjust the door lock position. The indicator light is on, should I check if the faucet is on?

Is the inlet pipe bent or the filter clogged? Is the water pressure too low? Is there electricity?

If there is electricity and no water ingress, it is a solenoid valve failure, and there is no electricity with a meter to detect whether the water level switch is on.

3.Do not heat.

The laundry is not heated, to see if the temperature of the water is very high? Is the temperature set by the thermostat knob too low? Did you choose a chiller? If not, should the heating tube be checked to see if it has burned out? Is the thermostat tube in good condition? Is the thermostat on and off normally?

4.No drainage.

Check if the drain is bent or too high. If not, open the filter door and check if the filter is blocked. If it is not blocked, check if the drain pipe can drain water.

Check whether the drain pump plug-in wire is loose, whether the drain pump has been burned, and whether the voltage is there. Failure to check the controller or computer board. If the drainage cannot be drained, it should be seen whether the drainage pump and drainage pipe are blocked, whether the impeller is stuck by foreign objects, and whether the soft water pipe from the outer cylinder to the pump is bent and the drainage is not smooth.

5.Do not spin dry.

First of all, see whether the micro-delay is in poor contact, and secondly, check the position of the program controller and whether the belt is worn, loose or broken; Whether the plug-in cable of the module and motor is not in good contact; module or motor failure; capacitive capacitance; The program controller is faulty or the plug-in contact is poor.

6.Washing, dehydration weakness, slow rotation.

Check whether the clothes are knotted and cause automatic protection of spinning. If not, check whether the belt is worn and loose, whether the belt bolt is broken, and whether the electronic module has been burned.

7.The door lock light is on, and water also enters, but not rollers.

Check whether the washing machine is heating and whether the belt is off, if not, check whether the electronic module is well plugged in and whether the electronic module is broken; Whether the motor wire strip is plugged in well and whether the motor is broken; Failure of pressure switch and heating pipe.

8.Do not tumble dry after spinning.

If the door has been closed, check: if it is not dried and does not roll after spinning, check whether the drying fuse is burned? Is the electronic module broken? Is the drying thermostat out of order? If the drum is not dry, check whether the motor is broken, whether the impeller is broken, and whether the heating pipe is faulty.

Common faults of drum motors include: motor winding burning, oil seal wear and oil leakage, bearing damage, transmission gear wear, etc.

What roller? What's on it?

Summary. What is the reason why the drum motor motor rotates and the drum does not rotate 1. The capacitance of the capacitor becomes smaller due to poor quality or too long use. It can be paralleled with a capacitor with a withstand voltage of 400 volts and a capacitance smaller than the original specification, or the capacitor of the original specification can be replaced.

2. The relevant bearings are poorly lubricated due to lack of oil, and the rotational resistance increases. The bearing should be filled with oil or replaced with a new bearing. 6. The power supply voltage is low.

7. If the belt of the washing machine is too loose, you can adjust the tightness of the belt by adjusting the fixing bolts of the motor, or replace the belt with a new one. 8. Washing too much laundry, exceeding the rated capacity, the general solution to this problem is to control the amount of laundry washed within the rated range. 9. The matching hole between the wave wheel and the rotation is seriously worn, and it is generally enough to replace the Weidong wave wheel.

The electric drum motor turns and the drum doesn't turn.

The reason why the drum washing machine does not rotate after powering on is that the drum washing machine originated in Ousen Qinquezhou, and the washing method is designed to imitate the principle of hitting clothes with a stick hammer. The drum washing machine is made of stainless steel inner barrel, mechanical program controller, phosphating, electrophoresis, spraying triple protection of the shell, and a number of bulky cement blocks to balance the huge centrifugal force generated when the drum rotates to do repetitive motion, plus the joint action of washing powder and water to make the clothes clean.

Because the materials are mainly made of steel, the life span is generally about 15-20 years. The drum washing machine is controlled by the micro first regret computer, the clothes are not entangled, the washing is uniform, and the wear rate is 10% smaller than that of the wave wheel washing machine, which can wash cashmere, wool, silk and other clothes to achieve comprehensive washing. It can also be heated to fully dissolve the laundry detergent and give full play to the decontamination effect of the laundry detergent.

Front-loading washing machines can form a highly concentrated laundry detergent in the barrel, bringing the ideal washing results while saving water. In addition to washing and dehydration, some drum washing machines have functions such as disinfection and sterilization, drying, and upper drainage, which meet the needs of consumers in different regions and living environments. However, traditional front-loading washing machines have the disadvantage of being time-consuming, generally taking about an hour, while old-fashioned front-loading washing machines cannot be opened during the washing process once the door is closed, making it inconvenient to add clothes.

And there is a common problem is power consumption.

Common faults and solutions of drum washing machine motors:

1. Starting failure.

When the electrical appliance is turned on, the motor cannot work, and the motor does not make any sound. The main reason for the analysis is that the starter electrical appliance matched with the motor is damaged (starting capacitor or resistor, contactor, thermal element, etc.), resulting in the motor can not operate normally.

Another situation is that the internal windings of the motor are short-circuited, and the local windings are burned, causing the motor to stop working. When the motor itself is suspected of fault, the easiest way to detect it is to use a megohmmeter to measure the resistance of each winding and to the ground.

2. Fault analysis in operation.

Due to various reasons in the operation of the motor, there will be failures, and the failures are divided into mechanical and electrical aspects.

Mechanical failure. On the mechanical side, there are failures such as sweeping, vibration, overheating and damage of bearings. The air gap between the stator and rotor of the asynchronous motor is very small, which is easy to cause the stator and rotor to collide. Generally, due to the wear of the hole in the shaft of the end cover or the wear and deformation of the joint between the end cover and the base, the base, the end cover and the rotor are not concentric, resulting in the sweeping.

Vibration should first be distinguished whether it is caused by the motor itself, or by poor transmission, or transmitted from the mechanical load end, and then ruled out according to the specific situation. The vibration caused by the motor itself is mostly caused by poor dynamic balance of the rotor, poor bearing, bending of the rotating shaft, or misalignment of the end cover, base and rotor, or due to the uneven installation foundation, inadequate installation and loose fasteners of the motor. Vibration not only generates noise, but also creates additional loads.

Electrical faults. Electrical faults include the phase loss of the stator winding, the reverse connection of the stator winding, the three-phase current imbalance, the winding short circuit and grounding, the winding overheating and the rotor broken strip and open circuit.

Most drum washing machines now use series motors, the kind that do not use electric capacitors. The wave wheel is an ordinary motor with a starting capacitor.

The drum washing machine washing and spinning dry are both one motor, and the motor has a total of 6 wires:

3 + laundry capacitor + transfer switch--- single-phase reversible circuit, slow speed, (120W).

Another 3 + dry capacitors--- single-phase unidirectional circuit, fast speed, (370W).

Shanghai Aisun Industrial Products specializes in manufacturing all kinds of motors, with complete varieties and excellent products.

Summary. 1. When the washing machine sometimes rotates, sometimes does not rotate, you should first observe in detail whether the washing machine has a rotating sound, buzzing sound, ticking sound, etc., if there is a sound, it is generally caused by the loosening of the washing machine belt, or the problem of the washing machine clutch. At this point, the belt of the washing machine should be tightened, and the screws of the clutch should be adjusted.

2. When the washing machine sometimes rotates and sometimes does not, if the washing machine does not make a sound, it is usually due to damage to the motor of the washing machine, or due to the capacitance problem of the motor, which causes the computer board of the washing machine to be damaged. At this point, the washing machine motor should be replaced with a new one.

Hello, I have seen your question and am sorting out the answer, please wait for a while 1.
