Single-phase motor, refers to by220VAn asynchronous motor that operates on a single-phase AC power supply. because220VThe power supply is very convenient and economical, and the household life electricity is also220VTherefore, single-phase motors are not only used in production, but also closely related to People's Daily life, especially with the increasing improvement of people's living standards, the consumption of single-phase motors for household appliances and equipment is also increasing. Here Senli motor XiaobianSingle-phase machineThe application and maintenance methods to make an analysis:
Single-phase motor generally refers to the use of single-phase AC power (AC220VSmall power single-phase asynchronous motor. This type of motor usually has a two-phase winding on the stator and an ordinary squirrel-cage rotor. The distribution of two-phase winding on the stator and the difference of power supply can produce different starting characteristics and running characteristics.
In the production of the application of micro water pump, pulp mill, thresher, mill, woodworking machinery, medical equipment, etc., in life, there are electric fans, hair dryers, exhaust fans, washing machines, refrigerators, etc., more types, but less power.
Maintenance method:
Common motor maintenance repair center motor maintenance process: cleaning the rotor→Replace carbon brushes or other parts→vacuumFGrade pressure dip paint→drying→Check the dynamic balance.
Note:
1The use environment should always be kept dry, the motor surface should be kept clean, and the air intake should not be hindered by dust, fibers, etc.
2When the thermal protection of the motor continues to act, it should be found that the fault comes from the motor or overload or the setting value of the protection device is too low, and it can be put into operation after the fault is eliminated.
3Good lubrication of the motor should be ensured during operation. General motor running5000About hours, that is, the grease should be added or replaced, and when the bearing is found to be overheated or lubricated during operation, the hydraulic grease should be replaced in time. When replacing the grease, the old lubricating oil should be cleaned, and the oil groove of the bearing and bearing cover should be cleaned with gasolineZL-3Lithium grease filled bearing between the inner and outer rings of the cavity1/2(right2Pole) and2/3(right4,6,8Extreme).
4When the life of the bearing ends, the vibration and noise of the motor operation will increase, and when the radial clearance of the bearing reaches a certain value, the bearing should be replaced.
5When disassembling the motor, the rotor can be removed from the extended end of the shaft or the non-extended end. If it is not necessary to remove the fan, it is more convenient to remove the rotor from the non-shaft extension, and the rotor should be removed from the stator to prevent damage to the stator winding or insulation.
6When replacing the winding, it is necessary to write down the form, size and number of turns, wire gauge, etc. of the original winding, when these data are lost, you should ask the manufacturer to change the original design winding at will, often making the motor a certain or several performance deterioration, or even unusable.
