YS6324 three-phase asynchronous motor

YS6324 three-phase asynchronous motor is a commonly used electromechanical product, and this motor is an old model. It is generally used in mechanical transmission and oil pumps. At that time, resources were relatively scarce, and our innovation capability was insufficient, making it difficult to develop new energy-saving products, so we still used old technologies. However, the appearance and heat dissipation were not very perfect, but the quality was exceptionally good, and some motors can often be used for decades without breaking down. This is why some customers choose the old models. The JW7134 three-phase asynchronous motor was produced under this environment, featuring stable quality and long service life, which meets the usage environment and scenarios of customers. Although new models have been launched now, the old models are still popular among old customers. We will also do our best to produce and ensure quality, so that customers can use our cost-effective products.

YS6324 three-phase asynchronous motor is an updated replacement product of the A02 series motors. This series of motors has excellent performance, energy saving and power saving, reliable structure and strong versatility. It can be used as a power device for small machine tools, medical equipment, household appliances, food processing and other machinery. Aluminum alloy casings or iron casings can be used as needed. The cooling method is IC411, and it can operate ratedly under the condition of altitude not exceeding 1000 meters. The rated voltage of the series motors is 380/220V, and the rated frequency is 50HZ. Motors with voltages such as 230V, 240V, 400V, 420V, 575V and 60HZ can be provided according to user needs. It is a fully enclosed self-fan-cooled squirrel-cage three-phase asynchronous motor for general purposes. The installation dimensions and power grades comply with IEC standards, the enclosure protection grade is IP44, the cooling method is IC411, and the continuous working system (S1). It is suitable for driving mechanical equipment without special requirements, such as machine tools, pumps, fans, compressors, mixers, transportation machinery, agricultural machinery, food machinery and so on.
The JW7134 three-phase asynchronous motor has the characteristics of high efficiency, energy saving, high locked-rotor torque, low noise, small vibration and safe and reliable operation. Y80~315 motors comply with the technical conditions of Y series (IP44) three-phase asynchronous motors JB/T9616-1999. Y355 motors comply with the technical conditions of Y series (IP44) three-phase asynchronous motors JB5274-91. Y80~315 motors adopt Class B insulation. Y355 motors adopt Class F insulation. The rated voltage is 380V, and the rated frequency is 50Hz. Motors with power of 3kW and below adopt Y connection; other power motors all adopt △ connection. The altitude of the motor's operating location shall not exceed 1000m; the ambient air temperature varies with seasons, but shall not exceed 40℃; the minimum ambient air temperature is -15℃: the average maximum relative humidity of the wettest month is 90%; and the average minimum temperature of this month shall not be higher than 25℃. The motor has one shaft extension. According to user needs, it can be made into double shaft extensions, and the second shaft extension can also transmit rated power, but only can be driven by couplings.
According to user needs, other motors with different powers, voltages, frequencies, wet tropical types (TH) and protection grades can also be supplied.

Transportation

YS6324 three-phase asynchronous motor will adopt the following protective measures before being shipped from the factory. Whenever changing the usage occasion or moving the motor, similar protective measures to the factory state should be adopted:
For motors with sliding bearing structures, the rotating shaft and bearings are equipped with transportation fixing devices.
For sliding bearings: flush all sliding bearings with lubricating oil and drain the lubricating oil, and seal all oil inlets, oil outlets and oil pipes with plugs, so as to achieve a good anti-corrosion effect.
For air-water coolers: drain the air-water coolers, and seal the inlet and outlet of the coolers with plugs.
The metal surfaces after machining (such as the shaft extension end) are coated with anti-corrosion coatings for anti-corrosion.
During transportation and storage, the motor shall ensure that the packaging box is not damaged or damp, and shall not be stacked, avoid dumping during transportation, and disassembly and transportation are not allowed (except for other transportation contracts).
Storage
If the JW7134 three-phase asynchronous motor 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 shall be re-coated with anti-rust oil and other coatings. After inspection and coating, repack and seal the motor in a clean and tidy place and put it into the warehouse. The warehouse should have dry air, good ventilation, the ambient temperature should often be kept below 40℃ and above 5℃, with moisture-proof, dust-proof, insect-proof and other protective conditions. The motor shall not be stacked to avoid dumping, 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.
Assembly of couplings
The following matters should be noted when assembling the couplings:
Use appropriate lifting tools to lift the couplings.
Remove the anti-corrosion coating on the shaft extension end, and ensure that the key grooves of the coupling and the shaft extension end are clean and free of burrs.
Check the dimensions of the shaft extension end and the coupling against the outline drawing.
The coupling should be heated evenly by heating and then heat-sleeved on the rotating shaft, and then cooled naturally.
Special tools should be used for assembling and disassembling the coupling to ensure that the motor shaft extension is not damaged.
Note: To avoid damaging the bearing, do not apply external force to the motor shaft and bearing when assembling the coupling.
Installation
When installing, YS6324 three-phase asynchronous motorthe rotating shaft must be horizontal (except for vertical motors), to ensure that the shaft center line of the motor is concentric with the shaft center line of the driven machinery.

The motor shaft extension is not allowed to bear additional axial loads and radial loads other than couplings (except for special motors). When using elastic couplings for connection, appropriate gaps should be left between the couplings.
When using sliding bearings, the distance between the motor shaft extension step and the bearing outer cover should be determined according to the data on the magnetic center indicator plate. When the motor is connected to the driven machinery by elastic couplings, the driven machinery should be equipped with an axial limiting device, and its axial end play should be <2mm (or according to the technical contract).
Note: Before rotating the sliding bearing, lubricating oil must be added.
