The asynchronous (induction) motor, whose rotor turns slightly slower than the stator's magnetic field and which needs no brushes or slip rings, is the most widely used motor type in industry. İzmir-based DRG Motor builds three-phase asynchronous motors on its own production line.

How an Asynchronous Motor Works

The three-phase stator winding creates a rotating magnetic field; this field induces current in the squirrel-cage rotor, and the rotor begins to turn. Because the rotor runs slightly behind synchronous speed (by the slip), it is called "asynchronous." The brushless design reduces maintenance and extends life.

Speed and Pole Relationship

On a 50 Hz network the synchronous speed depends on pole count: 2-pole 3000 rpm, 4-pole 1500 rpm, 6-pole 1000 rpm. The actual rotor speed is lower by the slip. The application's speed and torque needs decide the pole choice.

Durable Structure and Efficiency

A cast iron frame, IP55 protection and Class F insulation deliver reliability on lines running continuously (S1 duty). Under IEC 60034-30-1, efficiency classes from IE3 Premium to IE5 Ultra Premium lower energy spend.
