YS8022 three-phase asynchronous motor

People encounter both wonderful and unpleasant things every day. The key lies in how you resolve them. Once you figure it out in your heart, everything can be solved. Without further ado, let's see what product we are going to focus on today. We are going to introduce the YS8022 three-phase asynchronous motor. This electromechanical product is used in many kinds of electromechanical equipment, commonly on fans and some transmission machinery. Of course, customers can also use it according to their own needs, which can maximize the motor's performance and help customers reduce costs and increase efficiency. Whether the product is good or not can only be known after using it. We sincerely welcome customers to use it.

Preparations before installation
1. Carefully check whether all the data on the nameplate of the YS8022 three-phase asynchronous motor, such as rated power, voltage, frequency, speed, etc., match the actual requirements.

2. Carefully inspect whether the assembly of all parts is good, whether the fasteners are loose, and turn the rotor by hand to check for rubbing.
3. Use a 500V megohmmeter to measure the insulation resistance between each winding and between the winding and the ground. The measured insulation resistance during use shall not be less than 1MΩ, otherwise, drying treatment shall be carried out.
Installation
1. The vertical YS8022 three-phase asynchronous motor shall not bear any axial load during use.

2. During installation, ensure that the motor has good ventilation conditions, and the space reserved at the air inlet end of the fan cover shall not be less than the values specified in the following table. Frame size 50 63~132 160~180 200~355 Space (mm) 25 30
3. The direction of the junction box's cable gland can be adjusted among the three directions other than the shaft extension direction. When you need to re-determine the direction of the junction box's cable gland, you can remove the four screws of the junction box and shift the junction box.
4. Punch the rubber ring in the cable gland for wiring, and tighten the compression nut to achieve the anti-slip purpose.
5. After installation, check whether all fasteners and connectors are reliable, and turn the device by hand to ensure it rotates easily without rubbing.

Operation
1. This series of motors has a total of 6 wiring terminals, marked as U1, V1, W1, U2, V2, W2 respectively. Please connect the motor's outgoing lines according to the method indicated on the junction box cover.
2. YS8022 three-phase asynchronous motor shall continue to observe its starting condition during actual load operation, check whether the sound during operation is normal, and whether the actual load current exceeds the rated value on the nameplate. After running for 0.5~1 hour, stop the machine to check whether all mechanical connection parts of the motor are loose, whether the bearing is overheated and leaking oil, and whether there is rubbing between the stator and rotor. If no abnormalities are found, it can be officially put into use.

3. The motor should start at full voltage. If the power supply capacity is insufficient for full-voltage starting, step-down starting can be adopted. The starting torque of the motor decreases in direct proportion to the square of the voltage reduction. Y-Δ starting compensator is generally used for step-down starting.
Maintenance and overhaul
1.YS8022 three-phase asynchronous motor shall be used in accordance with the rated values on the nameplate, and overloading is strictly prohibited. Attention should also be paid to cleaning and inspection to prevent moisture or foreign matter from entering the interior of the machine.

2. When the motor is running, you should regularly record the readings of relevant instruments and thermometers, and the maintenance conditions during operation. At the same time, the fault handling should also be recorded for reference for future maintenance and overhaul.
3. Except for motors with frame size H80~132 which use sealed bearings and do not need to add lubricating grease, motors with frame size H160 and above are equipped with bearing lubricating grease injection and discharge devices. When needed at ordinary times, you can remove the oil injection plugs at the front and rear of the motor and inject lubricating grease with a grease gun.
4. The lubricating grease used for the bearing is Jinzhi HP-R. Generally, it should be replaced once every six months. If the grease is dark in color, with water droplets or dust accumulated on it, the grease has hardened and deteriorated, or the bearing is overheated, you should replace it with new grease immediately. When replacing the grease, remove the old grease, clean the bearing and bearing housing, and then add new lubricating grease. The amount of grease added should be 2/3 of the bearing chamber.
5. In order to eliminate faults and ensure operation quality, the motor should be overhauled regularly. Generally, minor overhauls are carried out every three months, and major overhauls are carried out every year. For minor overhauls, remove the dust and dirt on the exterior of the machine, keep the wiring board clean to avoid moisture and creeping electricity caused by accumulated dust, check the insulation resistance of the motor coil, joints, grounding wires, all fasteners and the connection of the transmission mechanism for looseness, and eliminate the found defects. For major overhauls, disassemble the motor. In addition to the items of minor overhauls, pay attention to the coils, check whether the coils are intact, whether the end bindings are damaged, clean the inside and outside of the machine body, check the wear of the motor's bearing and replace the lubricating grease.
Warranty period
If the user uses and stores the motor in accordance with the provisions of the operation and maintenance manual, our company guarantees that the motor can operate well within one year from the date of use (and the date of shipment from the factory shall not exceed two years). If the motor is damaged or operates abnormally due to poor manufacturing quality within the specified time, our company will repair it, replace parts or the motor free of charge for the user.
VII. Service Statement
1. Short-circuit between turns and between phases of the motor belongs to quality problems, but short-circuit caused by damage to the motor insulation due to overloading operation does not belong to manufacturing quality problems.
2. The motor's stator-rotor rubbing belongs to quality problems, but rubbing caused by bearing damage due to misalignment during installation or overloading operation does not belong to manufacturing quality problems.
3. Motor shaft breakage or motor faults or component damage caused by unreasonable installation and matching do not belong to manufacturing quality problems.
4. For the above situations that do not belong to manufacturing quality problems, our company can provide paid services according to the user's requirements. If the user judges that the fault is caused by the manufacturing quality of our company's products, please contact our after-sales service department, and the company will provide users with the most timely service in the shortest time.
