RG MOTOR – GENERAL PURPOSE INDUSTRIAL ELECTRIC MOTORS
“Power for Every Industry, Reliability for Every Application.”
What is a General Purpose Motor?
In industrial systems, general purpose electric motors — designed for use in various applications — are the most fundamental elements of industrial production.
These motors provide reliable power in every field, from pumps to compressors, from fan systems to conveyor lines.
DRG MOTOR General Purpose Series
is designed with the principles of high efficiency, low noise, and long-lasting construction.
It fully complies with both the IE3 energy efficiency standard and the demanding conditions of heavy-duty industrial operations.
“One motor, many solutions.”
DRG MOTOR – durable, silent, high-performance.
