Characteristics of Y series three-phase asynchronous motor Y series three-phase asynchronous motor not only meets the supporting needs of various departments of national economy, but also improves the interchangeability of similar products at home and abroad, which greatly facilitates the supporting and maintenance of imported equipment. Y-series three-phase asynchronous motors can be divided into two basic series: IP23 (protective type) and IP44 (closed type) according to the different protection levels of their casings. The characteristics of these two series asynchronous motors are briefly described as follows. 1 Features of Y series (IP23) Three-phase asynchronous motor Y series (IP23) is a three-phase protective cage asynchronous motor, and its protective structure is different from the closed structure of Y series IP44, but it is superior to the general drip-proof structure. It can prevent fingers from touching charged conductors or rotating parts in the shell; Prevent small solid foreign bodies with a diameter greater than 12 mm from entering; And prevent water dripping at an angle of 60 degrees or less along the vertical line from falling into the motor. Therefore, the shell protection level of Y series (IP23) three-phase asynchronous motor is obviously improved compared with J2 old series, which makes its operation safer and more reliable. The rated voltage of this series of three-phase asynchronous motors is 380 volts, the rated frequency is 50 Hz, and the power range is 5.5 kW → 132 kW. * * * It has 14 power levels, 6 frame numbers and 45 specifications. The power grades and installation dimensions of all series motors meet IEC international standards. The synchronous speed of the motor is 3000, 1500, 1000, 750 and 600 rpm. The winding is made of B-class insulation material, and the motors are all connected by A, and the cooling mode is IC0 1. 2. Characteristics of Y Series (IP44) Three-phase Asynchronous Motor Y Series (IP44) Three-phase Asynchronous Motor is a general-purpose fully enclosed self-fan cooling cage asynchronous motor, which is suitable for dragging various mechanical equipment without performance requirements, such as blowers, air compressors, water pumps, metal cutting machines, etc. Its rated voltage is 380 volts, rated frequency is 50 Hz, power range is 0.55→ 160 kW, and * * * has 22 power levels. The synchronous speed of the motor is 3000, 1500, 1000, 750 and 600 rpm, and its cooling mode is IC0 14 1. On the basis of Y series basic series, many different types of derivative series and special series can be derived by appropriately changing some electromagnetic structure design or processing technology. Y series (IP44) three-phase asynchronous motor has the following good performance and structural characteristics. (1) The efficiency level is relatively high. Y series (IP44) small three-phase asynchronous motor keeps the advantage of high efficiency of J02 series motor, and its weighted average efficiency is 0.4 13% higher than that of J02 series, reaching the international level. Due to the improvement of motor efficiency, it has brought great economic benefits of electricity saving to the society. (2) Good starting performance. The locked-rotor torque of Y series (IP44) motors is 33% higher than the average value of J02 series motors, and the starting torque reaches the level of JQ02 series motors with high starting torque. Ensure that the minimum torque is above 0.8 times the rated torque, and most of them reach or exceed 1 times the rated torque. Therefore, it has excellent starting performance and smooth starting with load. (3) Low noise and vibration. Y-series (IP44) three-phase asynchronous motors stipulate the standards of sound power and noise, which are divided into L-class and 2-class according to the noise limit for users to choose. Because this series adopts special bearings for motors, the running noise is greatly reduced. The measured noise is about 5→ 10 dB lower than the actual level of J02 series motors, and the vibration is also greatly reduced than that of J02 series motors. (4) Good protective performance. The structural design of Y-series (IP44) three-phase asynchronous motor meets the protection requirements for external solid objects and splashing water, and can effectively prevent foreign objects from harming the motor and human body. (5) Reliable operation and long service life. The winding of Y series (IP44) three-phase asynchronous motor is made of class B insulation material. When the altitude does not exceed 1000m and the cooling air temperature does not exceed 40℃, the temperature rise limit (resistance method) of the motor stator winding does not exceed 80K. Therefore, except for a few specifications, motors generally have a temperature rise margin above 15K. Larger temperature rise margin can prolong the service life of motor and improve the reliability of motor operation. (6) Beautiful appearance. The shapes of the main structural parts such as the end cover, junction box and wind hood of Y series (IP44) three-phase asynchronous motor are more beautiful and elegant than those of traditional old products. Compared with J02 series, the size and weight of the whole series of motors are reduced by 15% and 12% on average.

YR series motors adopt the latest integral box welding structure, which is light in weight and good in rigidity. The protection level of the basic series YR is IP23. Stator and rotor are made of Class B insulating material, and the ends are reliably fixed and bound. In the manufacturing process, it passed the impact resistance and ground pressure tests, and was treated by vacuum pressure impregnation solvent-free paint process (VPI). Therefore, the motor has excellent and reliable insulation performance, good mechanical strength and strong moisture-proof ability.
