The motor is designed and manufactured for the screw compressor. The base is a high-strength cast iron base. The junction box is located at the top or side of the extension base. The frame number is H132-H315, the installation method is divided into IMB3 and IMB5, the service factor is SF=1.15 or SF=1.25, the insulation level is F grade, and the temperature rise at the rated load is evaluated according to the B grade. When the coefficient is loaded, the temperature rise is evaluated by 90K, and the bearing temperature does not exceed 95 °C.
Center height (H): 132-400mm;
Power range (Power): 5.5-500kW
● This series of compressor special three-phase asynchronous motor is developed and designed by our company specially considering the special working conditions of the compressor. The center height is from H132~H400, the power is from 5.5-500kW, the insulation grade is F grade, and the rated temperature rise is pressed. Class B assessment, the temperature rise under the general service factor is assessed according to the F level, and the service factor is SF: 1.10, 1.15, 1.20 and other service factors (ie, the actual power of the motor can reach the rated power multiplied by the service factor).
● This series of motors uses a special bearing configuration to ensure that the bearings can work normally for a long time. Considering that the cable of the motor is directly connected to 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 pipe thread 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 the compressor.
● 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. The whole process of order, development, manufacturing, inspection, sales and service is controlled according to the requirements of ISO9001 quality system.
