The three-phase asynchronous motor works on the rotating magnetic field principle and is the most widely used motor type in industry. As an Izmir-based supplier, DRG Motor builds these motors in a range of power and speed options and sells directly across Izmir and beyond.

How a Three-Phase Asynchronous Motor Works

Three winding groups placed 120 degrees apart in the stator create a rotating magnetic field when fed with three-phase current. This field induces a current in the rotor, generating turning torque. Because the rotor turns slightly slower than the field, the motor is called asynchronous; its rugged design needs no brushes or commutator.

Speed and Pole Count Relationship

On a 50 Hz supply the synchronous speed is set by the pole count: 2 poles give 3000 rpm, 4 poles 1500 rpm and 6 poles 1000 rpm. The pole count is chosen for the speed and torque balance an application needs; pumps usually run 2 or 4 poles, while mixers favour 6 poles.

Features of DRG Three-Phase Motors

DRG Motor supplies three-phase asynchronous motors from 0.55 to 355 kW for the 400 V / 50 Hz supply. F-class insulation, IP55 protection and S1 continuous duty are standard. Cast iron or aluminium frames, with B3 foot-mounted, B5 flange-mounted or B14 face-mounted options, adapt to every application.

Choosing the Right Asynchronous Motor in Izmir

The right motor is determined by clarifying the application's power, speed and mounting needs. DRG Motor offers direct sales, technical support and fast delivery from its plant in Izmir; contact us for a quotation on your three-phase asynchronous motor requirements.
