Siemens Siemens 1LG0 series motor is the localization of the first low-voltage three-phase asynchronous standard motors, mainly for the fan category, pumps, compressors and HVAC class class load, for a variety of fixed speed and variable torque load transfer speed applications. As the localization of the Siemens motors, 1LG0 series has good technical features, and the price is relatively low, a higher price to let users directly benefit! Frame No. 80mm to 355mm nominal power range 0.55kW to 315kW Poles 2,4,6 certification mark European CEMEP efficiency rating: EFF2 (1.1-90 kW, 2,4-pole) CCC certification CE certificate protection class IP 55 rated voltage AC 220/380 / 660V 50Hz three-phase and three-phase AC 440V 60Hz frequency basic installation type B3, B6, B7, B8, V5, V6, B5, V1, V3, B35, V15, V36 cabinet material gray iron Cooling type Surface air cooling temperature class F insulation type DURIGNIT? IR 2000, downconversion use up to 500V, the voltage rise time ts> 0.1μs 1LG0 series motors have the following characteristics ---------------- -------------------------------------------------- -------------- ------ a) practical structural design of a flexible lead the direction of the motor terminal box mounting location can be on the left side of the motor, top and right side, while Junction box itself can be rotated 4 × 900 installed. The user can specify the location and direction of the junction box outlet port when ordering. Taking into account the thermal protection device is installed, the junction box using two holes into the line. New motor cover structural modeling shallow cover design, increasing the annular cooling ribs. Full range of cast iron junction box. ------ B) the superior performance of high-performance motor Motor protection class IP55 protection class standard configuration can be used for dusty or wet environments. Good insulation properties, increased motor life standard motor with Class F insulation system, according to Class B assessment (80K), increase the reliability of motor operation, increase the service life of the motor. Excellent new rotor manufacturing process rotor (shaft) processing equipment. After completion of the processing of each rotor will do the proper protection, and brushing protective coating. High standards of balancing precision control. Selection of high-performance bearings and grease, bearing the key components to ensure continuous long-term reliable operation. Advantages
