Motor bearing choose motor special low vibration, low noise bearing, no. 132 and below the base double sealed bearings, stretched out in the shaft with wave spring washers, take the moderate pressure on bearing, inhibit the motor of the vibration and noise produced when, no. 160 and above the base inside and outside cover structure, and in bearing parts adopt block circle axial fixed, effectively prevent the motor rotor shaft to move there.
For the safe and reliable operation of the motor, base number 160 and above motor bearing structure is set fill/discharge device, no. 250 and above motor engine, obligate bearing temperature monitoring sensor position.
Are widely used in industrial engineering, drag small and medium power equipment, the company now and agriculture machine motor; Cutting machine motor, light industry machine motor, mining machinery motor; Food machine motor; Plastic machine motor, and other enterprises, matching; In agriculture, used to drive pump motor, the threshers motor, the grinder motor and other agricultural products processing machinery, etc.; Pump products in industrial and mining enterprises, municipal water supply, farm irrigation, petroleum chemical industry, high-rise buildings, fire water supply, industrial water treatment and pure water, pharmacy, boiler, air-conditioning circulation system, and many other industries.
Y3 series and Y, Y2 series difference:
1. Using cold-rolled steel; 2. Use copper iron content with slightly below the Y2 series (Y2 series below Y series); 3. Three circles are the same, different shaped groove, grow up many different core;
4. Fan different (no matter size and shape are different types); 5. Y3 series motor efficiency standards is equivalent to the European Union EFF2 standard level, can achieve export the eu ranks;
6. Different base (shape improved heat, the number of steel and more high, on castings quality requires some); 7. The base, expand (small have 63, 71; the big were 400,, and 450-call it low voltage power series, in fact is the extension of Y3);
8. The noise reduction technology to do research, noise limit than Y2 series low.
