GOST standard motors can be widely used in various kinds of general use machineries like compressors,
Fans, pumps, machine tools, mills, transportation machines and so on, and can also be used in the hazardous
Areas with oil and chemical, steel plants, marine industry and mining industry.

Product Structure Characteristic
This series motors amount to the sixteenth frame sizes. Among of them, the frames and end-shields of
The frame size from H63 to H132 are made of cast iron or aluminium-alloy, and the frames of H160 or over
Are made of cast iron with sufficient mechanical strength. All cooling ribs of motors assume verical or
Horizontal distribution. So, the motor entirely looks very beautiful.
The terminal boxes are made of cast iron aluminium-alloy die-casting for frame size H63 up to H280 or high
Strenght cast iron for H315 up to H355 and located on the top or a side of the motor for offering users
Choose.
