Characteristics of YBX3 series High-Efficiency Flameproof Three-Phase Asynchronous Motor
1.The YBX3 high-efficiency flameproof three-phase asynchronous motor feature high standardization and strong compatibility.The entire series shares the same power ratings and installation dimensions as the YB series, demonstrating a certain degree of inheritance.
2.The motor features a unique parallel and vertical finned structure, which not only increases the heat dissipation area but also enhances the motor's aesthetic appeal. .
3.The motor has Class F insulation, but its temperature rise (resistance method) is still evaluated at 80K, which enhances both the operational reliability and service life of the motor.
This series of motors can operate at rated speed under the following environmental conditions
1.The maximum temperature of the ambient air varies with the seasons, DII type (factory electric motor) not exceeding 40 ℃;The minimum temperature of ambient air is -15 ℃.
2.Altitude not exceeding 1000m.
3.The maximum relative humidity of the ambient air shall not exceed 95% for electric motors used in non mining working faces underground in coal mines (when the temperature is 25 ℃) and 90% for electric motors used in factories (when the temperature is 25 ℃).
4.The electric motor used in while the one used in explosive gas mixing areas in factories has a maximum surface temperature of 135 ℃, the explosion-proof mark is Ex db Ⅱ B T4 Gb.
5.Rated voltage of electric motors: 380V, 660V, and 380/660V. Electric motors with a power of 3KW or less are rated at 380V.
6.The rated frequency of the electric motor is 50Hz.
7.The cooling method for the electric motor is IC411 (installed on the motor shaft without an independent fan).
8.The protection level of the motor casing is IP55 (dustproof, anti spray motor).
9.The installation type of the electric motor is IMB3; IMB5; IMB35; IMB14; IMB34; Six types including IMV1.
