Siemens Crane Duty Motor

Overview
The New IS: 12615 is based on the International Standard IEC 60034-30 (2008) which defines New Efficiency Classification for single speed, three phase, induction motors. The new IS: 12615 covers single speed, three-phase, 50Hz, cage induction motors that: have rated voltage ≤1000V; have a rated output 0.37kW ≤ PN ≤ 375kW; have either 2, 4 or 6 poles; meet frame size to output relation as stipulated in IS: 1231 (for outputs covered by IS:1231); are rated on the basis of either duty type S1 (continuous duty) or S3 (intermittent periodic duty) with rated cyclic duration factor of 80% or higher; are capable of operating direct on-line; are designed for operation on virtually sinusoidal and balanced voltage conditions as defined in 7.2.1 of IS/IEC 60034-1; designed for an ambient temperature not exceeding 40°C and altitude not exceeding 1000m; have degree of protection IP44 or superior; have method of cooling IC411 in accordance with IS 6362 / IEC 60034-6; have service factor not exceeding 1.0.
The Efficiency classes defined are:
IE1 – Standard Efficiency
IE2 – High Efficiency
IE3 – Premium Efficiency
The New IS:12615 also stipulates that for motors to be classified as “Energy Efficient”, these must meet at least IE2 efficiency values.
