Compressors are machines that demand high, steady torque to compress air, which is why the drive motor is regarded as the heart of the compressor. On a compressor running under continuous load, the motor's efficiency, cooling and durability directly set the running cost. In its İzmir production, DRG Motor offers powerful AC motors suited to compressor applications.

What a Compressor Motor Must Deliver

A compressor asks for a load that varies through the cycle; the motor must produce high starting torque and hold its speed as the load rises. Three-phase induction motors are ideal for this duty, offering a stable torque curve against changing load thanks to the squirrel-cage rotor.

Choosing Speed and Power

Piston compressors usually call for 4-pole 1500 rpm, while screw compressors may use 2-pole 3000 rpm depending on the application. Power is selected in the 0.55–355 kW range according to the compressor's air flow and pressure. The right speed-to-power match affects both efficiency and life.

Durability in Continuous Duty

Compressors often run in S1 continuous duty. Class F insulation, IP55 protection and a cast iron frame that dissipates heat well are therefore important for a fault-free life. An IE3 Premium or IE4 Super Premium efficiency class also lowers energy cost given the continuous consumption.

DRG Motor for Your Compressor

Once you share your compressor type, air flow and duty cycle, we determine the motor in the most suitable power and speed. DRG Motor prepares a current quote with AC motors that combine power and efficiency in compressor drives.
