When installing Y series three-phase asynchronous motor, what aspects should be noticed? How do I start for the initial installer?
First of all, the installation site and installation basis of the motor must be determined.
The installation site of the motor should not exceed 100 () m elevation; the general purpose motor installation site should be dry and clean, the motor should be well ventilated, and the other equipment should have a certain interval to facilitate inspection, monitoring and cleaning, the ambient temperature at 40 degrees, and the need to prevent strong radiation; installation foundation should Sturdy, strong and rigid, the mounting surface should be leveled to ensure balanced operation of the motor.
What work to prepare before installation
Before the motor is open, check whether the package is intact and moisten. After opening the hood, we should carefully clear the dust and rust layer on the motor, check carefully in the process of transportation, whether there is any deformation and damage, the fasteners are loose or off, the rotor is flexible, whether the inscription data meets the requirements, and uses the 500VMQ The meter should measure the high voltage resistance, the insulation resistance should be no less than 1MQ, otherwise the winding should be dried, but the temperature should not exceed J20 C.
In addition, when the coupling is used, the center line of the motor axis and the axle center line of the load machine should be reconnected to avoid the strong vibration, coupling and abnormal sound of the motor in the moving line. The installation deviation of the device is as follows: the allowable deviation of the 2 pole motor is 0.015mm, and the deviation of the 4, 6 and 8 pole motors is 0.04mm.
