DRG MOTOR – 3-PHASE ASYNCHRONOUS ELECTRIC MOTORS
“Powering the Industry.”
What is a 3-Phase Asynchronous Motor? Why Choose It?
In industrial facilities, the largest share of energy consumption comes from motor systems.
3-phase asynchronous motors are the most reliable power sources in industry due to their durability, high torque, efficiency, and long service life.
Operating on the asynchronous principle, these motors rotate the rotor through the rotating magnetic field generated by the three-phase alternating current in the stator.
Thanks to their simple design, low maintenance requirements, and high performance, they are the most widely used motor type worldwide.
