3KW dedicated motor for aerator

1Definition of motor:

motorIt refers to the law of electromagnetic induction

2An electromagnetic device that converts or transmits electrical energy. Its main function is to generate driving torque as an electrical appliance

Or various mechanical power sources.Motor for aerator:According to the different working power sources of motors, they can be classified into DC motors and AC motors. Among them, AC motors are also divided into single-phase motors and three-phase motors, among which the impeller type aerator uses AC motors. Single phase is220VVoltage, three-phase is

3380V

3.1.The usage environment should be kept dry regularly, the surface of the motor should be kept clean, and the air inlet should not be obstructed by dust, fibers, etc.

3.2.When the thermal protection of the motor continues to operate, it should be determined whether the fault comes from the motor, overload, or the setting value of the protection device is too low. Only after the fault occurs can it be put into operation.50003.3.Good lubrication of the motor should be ensured during operation. General operation of electric motorsAfter about an hour, the lubricating grease should be replenished or replaced. If the bearing overheats or the lubrication deteriorates during operation, the hydraulic system should replace the lubricating grease in a timely manner. When replacing the lubricating grease, the old lubricating oil should be used and the oil grooves of the bearings and bearing covers should be cleaned with gasoline. ThenZL-3Filling the cavity between the inner and outer rings of the bearing with lithium grease21/2(Yes)Extreme) and42/36(Yes)8、

、Extremely).

3.4.When the service life of the bearing is over, the vibration and noise of the motor operation will increase. When the radial clearance of the bearing reaches the following value, the bearing should be replaced.3.5.disassemble

motorWhen, the rotor can be removed from either the extended or non extended end of the shaft. If it is not necessary to remove the fan, it is more convenient to remove the rotor from the non shaft extension end. When removing the rotor from the stator, care should be taken to prevent damage to the stator winding or insulation.

43.6.

When replacing the winding, it is necessary to record the form, size, number of turns, wire gauge, etc. of the original winding. When these data are lost, they should be requested from the manufacturer. Changing the original design winding arbitrarily often deteriorates one or several performance aspects of the motor, and even renders it unusable.
