YS6334 three-phase asynchronous motor

YS6334 three-phase asynchronous motorWe must seize the development opportunities and strive to produce cost-effective and genuine products for our customers. Foreign brands used to be aloof. One day we will draw level with and surpass them.
The sense of urgency of "striving for progress, or we will fall behind" stems from a profound judgment of the times and trends.
Looking outward, "The world today is undergoing major changes unseen in a century, and scientific and technological innovation is one of the key variables" and "The competition for the制高点 of science and technology is unprecedentedly fierce". At the same time, external suppression and containment may escalate at any time, and the risks of "decoupling and breaking supply chains" and "small yard with high walls" are intensifying. It is urgent to accelerate the achievement of high-level scientific and technological self-reliance and self-improvement, so as to seize the historical initiative and development initiative.
Looking inward, the path of Chinese-style modernization has reached a critical juncture. Industrial transformation and upgrading and the conversion of old and new growth drivers are facing arduous tasks. Seizing the opportunity of productivity leap brought by this round of scientific and technological revolution and industrial transformation will promote the transformation of China's science and technology and industrial development from "followers" to "leaders".
The position and role of scientific and technological innovation in promoting high-quality development and advancing Chinese-style modernization are more prominent. Supporting the great cause of national rejuvenation with the "strong bones" of high-level scientific and technological self-reliance and self-improvement is an urgent requirement and an inevitable choice.
Motor installation methods
1.YS6334 three-phase asynchronous motorCouplings, spur gears and belts are allowed.

2. Pulley drive is not recommended for 2-pole motors above 4kW and 4-pole motors above 30kW. If a small pulley is selected, the transmission range of the V-belt can be expanded. For the fan end of a double shaft extension motor, only coupling drive is allowed.
3. When using pulley drive, the shaft centerline of the motor shall be parallel to the load centerline, and the centerline of the pulley shall be perpendicular to the shaft centerline. When using coupling drive, the shaft centerline of the motor shall coincide with the load centerline.
4. For vertically installed motors, the shaft extension shall not carry any other axial load devices except pulleys (or loads equivalent to ordinary pulleys).
5. The motor shall be installed to ensure good ventilation and cooling conditions, and shall not be used in places exposed to direct sunlight or rain.
Motor operation
1.YS6334 three-phase asynchronous motor shall be properly grounded. There is a grounding device at the lower right of the junction box. If necessary, the motor can also be grounded through the foot bolts or flange fastening bolts.

2. There are 6 terminals on the motor junction board, marked with the following signs respectively:
3. Connect into delta or star configuration as specified on the nameplate. Please connect correctly according to the wiring diagram.
When the power phase sequence A, B, C correspond to the terminal marks U1, V1, W1 respectively, the rotation direction of the motor is clockwise when viewed from the shaft extension end. Changing the power phase sequence will reverse the rotation direction of the motor.
Pre-installation preparations
1.YS6334 three-phase asynchronous motorCheck whether the package is intact and whether there is any sign of moisture before unpacking.

2. After unpacking the motor, carefully remove the dust and anti-rust layer on the motor.
3. Check whether the nameplate data of the motor meet the requirements.
4. Carefully check whether all parts during the motor operation process are loose or fallen off.
5. Use a 1000V megohmmeter (or other resistance measuring instruments) to measure the insulation resistance, which shall not be less than 5 megohms. Otherwise, dry the stator winding. The temperature during drying shall not exceed 120℃.
Motor storage and transportation
1. JW5622 three-phase motors shall be stored in a dry environment to avoid drastic changes in ambient temperature.
2. Motors shall not be stacked too high during storage, so as not to damage the packaging of the lower layer motors, and shall be prevented from falling over or being placed upside down.
3. If the motor has been stored in a humid environment for a long time, confirm that the insulation resistance of the motor is greater than 1 megohm before use. If it is lower than 1 megohm, drying treatment shall be carried out. If the insulation resistance still cannot reach 1 megohm after drying, the motor must be sent for repair.
4. After long-term storage of the motor, check whether the bearing is rusty. If rusty, replace it with a new one. At the same time, add new lubricating grease of the rated weight. If the motor has not been used for more than one and a half years since storage, replace the lubricating grease before use.
Motor maintenance and repair
1. The working environment shall always be kept dry. The surface of the motor shall be kept clean, and the air inlet shall not be blocked by dust, fibers and other substances.
2. When the thermal protection and short-circuit protection of the motor act continuously, find out whether the fault comes from the motor, overload or the protection device setting value is too low. Only after the fault is cleared can the motor be put into operation again.
3. Ensure good lubrication of the motor during operation. For general motors, run for about 5000 hours before replenishing or replacing the lubricating grease (sealed bearings do not need to replace the lubricating grease during their service life). If the bearing overheats or the lubricating grease deteriorates during operation, replace the lubricating grease in time. When replacing the lubricating grease, remove the old lubricating grease, clean the oil grooves of the bearing and bearing cover with gasoline, and then fill ZL-3 lithium base lubricating grease into 1/2 of the cavity between the inner and outer rings of the bearing (for 2-pole motors) or 2/3 (for 4, 6, 8-pole motors).
4. When the service life of the bearing ends, the vibration and noise during motor operation will increase significantly. When the radial clearance of the bearing reaches the following values, replace the bearing.
5. Disassemble YS6334 three-phase asynchronous motor. The rotor can be taken out from the shaft extension end or the non-shaft extension end. If there is no need to remove the fan, it is more convenient to take out the rotor from the non-shaft extension end. When pulling the rotor out of the stator, prevent damage to the stator winding or insulation.

6. When replacing the winding, write down the form, size, number of turns, wire gauge and other data of the original winding. If these data are lost, obtain them from the manufacturer. Randomly changing the original designed winding often deteriorates one or more performances of the motor, and even makes it unusable.
