LFF series high efficiency dust suppression fan special motor
Center height (H): 132-250mm;
Power Range (Power): 11-55kW
Our company specially designed and developed the electric motor specially designed for the special working condition of the dust suppression fan. The center height is from H132 to H250, the power is from 5.5kW to 75kW, the insulation grade is F grade, and the rated temperature rises. Grade B assessment. Compared with the standard series motor, the same speed is the same as the standard series motor, and the structure is compact.
● This series of motors according to working conditions, especially for low temperature environment, using special bearing configuration to ensure that the bearing can work normally for a long time. In addition, considering that the cable of the motor is directly connected with the electric control box of the compressor, the configuration of the extension lead wire can be made for the customer, and the cable sheath tube is used for protection, and the tube nut sleeve is provided at both ends. This series of motors has the advantages of high efficiency, energy saving, stable performance, and is suitable for long-term continuous operation of dust suppression and fog guns.
● The performance and installation dimensions of this series of motors comply with IEC60034 standard, DIN42673 standard and GB755 standard and related professional technical standards. And the company has passed ISO9001 international quality system certification.
