YS7124 three-phase asynchronous motor

Time really flies, and today is already the end of the month. I really want to ask myself. What have I gained this month? Compared with last month, have I made progress? Or just standing still. This problem can be said to be the epitome of modern wage earners. Things are earned through one's own hard work. No pain, no gain. So, we still need to calm down and take one step at a time.
Today, we are introducing a commonly used electromechanical product, its model is YS7124 three-phase asynchronous motor. This motor is 370W, 1400 rpm. Its power belongs to the small series. It can be installed with fans, reducers, oil pumps and other electromechanical equipment. There are more usages waiting for you to discover. The motor shaft diameter is 14, keyway is 5, shaft length is 30. When choosing, you must make the right choice. A wrong choice will delay use. If you need non-standard shafts or different voltages, you can contact us. We will wholeheartedly provide you with thoughtful and efficient services.
Operation 1, This series of YS7124 three-phase asynchronous motor has a total of 6 wiring terminals, marked as U1, V1, W1, U2, V2, W2 respectively. Please follow the wiring method indicated on the junction box cover when connecting the motor lead wires.

2, During actual load operation, you should continue to observe its starting condition, whether the operating sound is normal, and whether the actual load current exceeds the rated value on the nameplate. After running for 0.5~1 hour, stop the motor to check whether all mechanical connection parts are loose, whether the bearing is overheated and leaking oil, and whether there is friction between the stator and rotor. If no abnormal conditions are found, it can be officially put into use.
3. The motor should be started 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 proportion to the square of the voltage drop. Step-down starting generally uses Y-Δ starting compensator.
Preparation before installation of YS7124 three-phase asynchronous motor

1. Carefully check all the data on the nameplate, such as rated power, voltage, frequency, speed, etc., to see if they match the actual requirements.
2, Carefully check whether the assembly of each component is good, whether the fasteners are loose, and turn the rotor by hand to check for friction.
3, Use a 500V megohmmeter to measure the insulation resistance between each winding and between the winding and the ground. The insulation resistance measured during use shall not be less than 1MΩ, otherwise drying treatment shall be carried out.
Installation 1, Vertical YS7124 three-phase asynchronous motor shall not bear any axial load during use.

2, During installation, good ventilation conditions for the motor shall be ensured, 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.
3, The direction of the cable gland of the junction box can be adjusted among the other three directions except the shaft extension direction. When you need to re-determine the direction of the junction box 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 before wiring, and tighten the compression nut to meet the waterproof and shockproof requirements.
5· After installation, check whether all fasteners and connecting parts are reliable, and turn the device by hand to make sure it rotates easily without friction.
Maintenance and overhaul 1, YS7124 three-phase asynchronous motor shall be used in accordance with the rated values indicated on the nameplate, never overload it, and pay attention 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 meters 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 H80~132 motors that use sealed bearings and do not need to add grease, motors above H160 are equipped with bearing 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 use an oil gun to inject grease.
4· The grease used for the bearings is Jinzhi HP-R. Generally, the grease should be replaced once every six months. If you find that 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, the old grease should be removed, the bearing and bearing cover should be cleaned, and then new grease should be added. The amount of grease added should be 2/3 of the bearing cavity.
5, In order to eliminate motor accidents and ensure operation quality, the motor should be overhauled regularly. Generally, a minor overhaul is conducted every three months, and a major overhaul is conducted every year. For minor overhauls, remove the dust and dirt on the exterior of the machine, keep the wiring board clean to avoid dust accumulation and moisture that may cause creeping discharge, 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, the motor should be disassembled. 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 bearings and replace the 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 will operate properly within one year of use. If the motor is damaged or malfunctions due to poor manufacturing quality within the specified time, our company will repair it, replace parts or the motor for the user free of charge.
