Voltages are defined according to the IEC60038 standard.
The so-called low voltage refers to the AC voltage below 1000V.
Typical voltages are 230, 400, 500 and 690V 50Hz and 230, 460 and 575V 60Hz
sA high voltage motor is a motor with a rated voltage of 1000V or more. The voltages of 6000V and 10000V are often used. Due to the different power grids abroad, there are also voltage levels of 3300V and 6600V.
