technology After finishing, all rotors are protected with corrosion-resistant paint Precise inspection system is applied to achieve high Terminal boxes are mounted in basic design on top of the motor The terminal boxes can be turned x 90º to allow cable standard balancing result Esso Unirex N3 grease is used as standard bearing lubricant that ensures longer bearing lifetime entry from each direction Different cable entry directions and terminal box positions can be offered as options.The double Choose higher capability bearing and grease cable entries allow easy connection of thermal protections Choose Esso Unirex N3 grease, assure long credible operation Innovated design The end shield on DE is equiped with circular ribs to expand of the bearing Conditions surface area Terminal box is cast iron for all frame sizes Altitude should be lower than 1000 m High quality performance Ambient temperature -20ºC ~+40ºC Relative humidity High degrees of protection All the motors are designed for IP55,They are suitable for dusty or humid surroundings Class F insulation offers higher reliability and security Standard motors are designed for class F and used in class B Temperature

supplied according to the following The rated output refers to continuous duty according to IEC 60 standard: 034-1 at a frequency of 50Hz, a coolant temperature (CT) of 40ºC and a site altitude of up to 1000m above sea level Rated voltage: 220V/380V, 380V/660V Frequency: 50Hz Rated voltage: 440V, Frequency: 60Hz.These standand comply If the actual operating conditions deviate from this class, the with IEC 60038 of voltage deviation maximum output should be adjusted according to the following 5% frequency deviation 2% table Application environment Altitude above sea level ASL , in: m Coolant temperature, in: ºC 0.1s at the motor terminals Torque/speed characteristic Power/speed characteristic 1.Torque almost constant; power proportional to speed Connection of the motors 2.Torque increases proportionally with the speed; power In addition to the restrictions applying to mains-connected proportional to the square of the speed 3.Torque increases proportionally with the square of the speed; power proportional to the cube of the speed (applicable for 1LG0 series motors) 4.Torque decreases in inverse proportion to the speed; power constant Siemens 1LG0 series products are designed to drive pumps, fans, compressors and HVAC in both constant and variable speed applications For other complex applications, we still machines, the maximum permissible conductor cross-sections for the converter must also be kept in mind when the motors are connected Mechanical stress, grease life Due to the higher speed beyond the rated speed value and the resulting increased vibration, the mechanical balance quality changes and the bearings are under greater mechanical stress This reduces the grease life and the bearing life (enquire if necessary) recommend Siemens imported motors Motor temperature protection The 1LG0 motors can be supplied with PTC thermistors or PT100 temperature sensors for alarms and tripping PTC thermistors are absolutely necessary if these motors are used for converter-fed operation! 11 Order number 10 11 12 Motor serial Frame size 80 ~ 355 S = short (0 M = medium L = long 2) (3 5) (6 8) Number Of Poles Design Voltage, connections and frequency voltage
