Converter-fed operation up to 500 V +10 % line voltage
The standard insulation of the 1LA and 1LG motors is designed such that operation on the converter is possible at line voltages up to 500 V +10 % in motorized operation (for motor series 1LA8, up to 500 V +10 % generally). This also applies for operation with a pulse-controlled AC converter with voltage rise times of ts > 0.1 μs at the motor terminals (IGBT transistors). At higher voltages, the motors require increased insulation resistance. Please inquire in the case of converter-fed operation with motors with protruding connection cables (order codes L44, L45, L47, L48, L49, L51 and L52).
The 1LA8 non-standard motors of the types specially identified for converter-fed operation (the 9th and 10th position of the Order No. is filled with "PB", "PC" or "PE") have an insulated motor bearing as standard at the non-drive end NDE. The motors are equipped with standard insulation and standard rotors and are suitable for mains-fed and converter-fed operation. For further information, see Part 3 of this catalog "SIMOTICS N-compact Non-Standard Motors".
Converter-fed operation up to 690 V +10 % line voltage
1LA5, 1LA7 and 1LG6 standard motors as well as 1LA8 and 1PQ8 non-standard motors are also available with a higher insulation resistance of the winding system for operation on the converter with supply voltages from 500 to 690 V (+10 %), and do not usually require a filter. These motors are identified by an "M" in the 10th digit of the Order No. (e.g. 1LA83152PM).
With the reinforced insulating system, there is less space in the grooves in motor series 1LA8 and 1PQ8 for the same number of windings compared to the normal version, which slightly reduces the rated output of these motors. For further information, see Part 3 of this catalog "SIMOTICS N-compact Non-Standard Motors".
Note:
The configuration tool SIZER for Siemens Drives is available for configuring converter-fed motors.
