High Voltage Motor Application
A high-voltage motor is a type of motor defined and defined for the rated voltage of the motor, which corresponds to a low-voltage motor. From the power comparison of the motors, it can be found that the power of high-voltage motors is generally relatively large, mainly because the characteristics of high-voltage motors with high voltage and low current are used, which makes the selection of motor conductor area have a greater degree of freedom. However, the insulation structure of high-voltage motors is much more complicated than that of low-voltage motors, mainly reflected in the motor windings and wiring systems.
Compared with the application fields of motors, high-voltage motors are more used in the industrial field; and people's daily work and living places use low-voltage motors. That is, the power characteristics of the motor application site, which basically defines the rated voltage of the motor.
Domestic high-voltage motors basically have three voltage levels, 3000V, 6000V and 10000V, while high-voltage motors used in other countries are different from our country's voltage according to the local high-voltage power supply settings, such as 3300V, 6600V and 11000V, etc. .
High-voltage motors are mainly used in some machinery that needs to be driven, such as compressors, water pumps, crushers, cutting machine tools, transportation machinery and other equipment, for mining, machinery industry, petrochemical industry, generators and other industrial equipment.
From the analysis of the application characteristics of the motor, compared with the low-voltage motor, the high-voltage motor has relatively small requirements on the power distribution facilities due to the small current, such as cable diameter, switches, etc. Therefore, for the user, the power is relatively large. high-voltage or low-voltage motors can be selected according to the power adaption; but from the manufacturer's point of view, the production and manufacturing process of high-voltage motors, especially the electrical manufacturing process, high-voltage motors are more complicated than low-voltage motors, although many motors are currently Manufacturers, the manufacturing process of high-voltage motors is relatively mature, but the inherent corona and shaft current problems of high-voltage motors have plagued motor manufacturers and users from time to time.
