JW5022 three-phase asynchronous motor

Due to the unique domestic consumer preferences, JW5022 three-phase asynchronous motor has become the favorite of most people. This is due to both corporate structure factors and the aesthetic taste of Chinese people. Therefore, purchasing a JW6314 three-phase motor has become a consideration for many customers. Considering the equipment use, the space, comfort, configuration and power performance must not be too poor. From the current motor market, there are quite a few products with outstanding product strength and cost performance. In this issue, we recommend this motor with excellent quality and cost performance. We hope to receive support and love from the majority of customers.

Pre-installation preparations

JW5022 three-phase asynchronous motor should be inspected for complete and undamaged packaging and signs of moisture before unpacking. After opening the cover, carefully remove the dust and anti-rust layer on the motor, carefully check whether there is deformation and damage during transportation, whether the fasteners are loose or fallen off, whether the rotor rotates flexibly, whether the nameplate data meets the requirements, and use a 500V MΩ meter to measure the high-voltage resistance. The insulation resistance should not be less than 1MΩ, otherwise the windings should be dried, but the treatment temperature should not exceed 120℃.
Motor installation site and installation foundation

JW5022 three-phase asynchronous motor shall be installed at an altitude of no more than 100m; the installation site for general-purpose motors shall be dry and clean. The surrounding area of the motor shall be well ventilated, and a certain interval shall be left from other equipment to facilitate inspection, monitoring and cleaning. The ambient temperature shall be below 40℃, and strong radiation shall be prevented; the installation foundation shall be firm, solid and have certain rigidity, and the installation surface shall be flat to ensure the balanced operation of the motor.
JW series three-phase asynchronous motors

JW5022 three-phase asynchronous motor is a new series of products designed uniformly across the country and will replace the JO series motors. The Y-series three-phase asynchronous motors have the characteristics of high efficiency, energy saving, low noise and low vibration. 2. Y-series (IP23) three-phase asynchronous motors: Y-series (IP23) three-phase asynchronous motors have frame numbers 160-315. Their protective structure is different from the enclosed IP44 type, but is superior to the drip-proof type. Their volume is reduced by 20% and 15% respectively compared with the Y-series (IP44).
Storage

JW5022 three-phase asynchronous motor If it is not installed immediately after being transported to the owner's site, it should also be unpacked, cleaned and inspected as above, and the exposed metal surfaces should be re-coated with anti-rust oil and other sealing materials. After inspection and coating, repack and seal the motor in a clean and tidy place and store it in the warehouse. The warehouse should have dry air and good ventilation, the ambient temperature should be kept between 5℃ and 40℃, with moisture-proof, dust-proof and insect-proof protection conditions. The motors shall not be stacked to prevent tipping, and necessary anti-rust protection treatment shall be carried out on the motor shaft extension, slip rings and exposed fasteners. Unpack and inspect once every six months to check whether the temporary coating has deteriorated, so as to improve the storage conditions in time.

JW5022 three-phase asynchronous motor installation
During installation, the motor shaft must be horizontal (except vertical motors), to ensure that the motor shaft centerline is concentric with the shaft centerline of the driven machinery. The motor shaft extension shall not bear additional axial loads and radial loads other than couplings (except special motors). When using elastic couplings for connection, appropriate clearance shall be left between the couplings.
When using sliding bearings, the distance between the motor shaft extension step and the bearing outer cover shall be determined according to the data on the magnetic center indicator. When the motor is connected to the driven machinery with an elastic coupling, the driven machinery shall be equipped with an axial limit device, and its axial end play shall be ≤2mm (or according to the technical agreement).
Note: Lubricating oil must be added before rotating the sliding bearing.
Alignment
Rotate the rotor and observe the axial float of the rotor.
For the JW5022 three-phase asynchronous motor connected by a coupling, rotate both the motor shaft and the equipment shaft at the same time, measure the readings of horizontal, angular and axial deviations at four different positions: top, bottom, left end and right end, and make records. (For vertically installed motors, adjust the detection positions accordingly).

Adjust the motor vertically by adjusting bolts or other equipment. Please note that the alignment accuracy may be affected by thermal expansion and contraction.
During the alignment process, prepare a certain number of gaskets or wedges, pad them under the motor base, and tighten the fixing bolts. Check again whether the motor is aligned, and recalibrate if necessary.
