Detailed Description
Y2 series three-phase motor
Y2 series three-phase motor basic frame from H63 ~ H355. The motor speed of 2950 r/min, 1450 r/min and 980 r/min, 785 r/min, power 0.55 KW to 315 KW. At the same time, Y2 series three-phase asynchronous motor can also be designed to be derived series and other special series and different voltages and different frequency of the three-phase asynchronous motor. The user can according to different requirements to choose
Y2 series three phase asynchronous motor basic conditions of use：
1) the environment temperature changes with the seasons, but not more than 40 ℃, the lowest for 15 ℃;
2）Ambient air is mean monthly the highest rather humidity is 90%;
3) altitude: not more than 1000 m;
4) : rated frequency 50 hz;
5) rated voltage, 380 v; Insulation class F;
6) a week; S1 (continuous rated works);
7) cooling way; ICO141 (fan fan cooling);
8) connection; Power below 3 kw (4 HP) and for Y; Power in the 4 kw (5.5 HP
High degree of standardization, general
B, Y2 series motor has a unique shape structure of parallel vertical fin, both to increase the cooling area, changed the traditional motor aesthetic appearance.
C, adopted to reduce the noise, vibration measures, the noise of the motor, vibration are relatively low, respectively 5.55 dB (A) and lower than the Y series of about 0.5 ~ 0.9 mm/S.
D, has the high locked-rotor torque, maximum torque, the minimum torque power equal to the rated torque of Y series motor is 0.11 ~ 0.22 times higher.
E, has lower multiples locked-rotor electric current and the ratio of the rated current of the motor Y series of the same specification low around 0.2 ~ 0.4 times.
F, Y2 series motor load rate is around 75%, which has the best efficiency characteristics. G, Y2 series motor insulation class is F, the highest working temperature is 155 ℃, the temperature rise allowed 110 k, but still according to the class B insulation motor temperature rise, the highest working temperature 130 ℃, the temperature of 80 k. At the same time, the measured temperature rise all around 50 k ~ 70 k, this series of motor temperature rise margin is large, the use of safe and reliable.
