ULTRA-EFFICIENT ASYNCHRONOUS ELECTRIC MOTOR are asynchronous (induction) motors, the most widely used motor type in industry. Since they contain no wearing parts such as brushes or commutators, they are durable, long-lasting and low-maintenance.

Advantages of Asynchronous Motors

A squirrel-cage asynchronous motor has no brushes and no commutator, so it keeps running in dusty plants with bearing service alone, at high efficiency and low operating cost. A wide power range and easy availability make them the most common choice.

Single-Phase and Three-Phase Options

Single-phase motors are powered from a 220 V supply for low-power applications, and three-phase motors from a 380 V supply for high-power industrial applications. Three-phase motors are more efficient and longer-lasting at the same power.

Areas of Use

Asynchronous motors are used in almost every industrial application, especially pumps, fans, compressors, conveyors and general drive systems.

Production Quality and Testing Process

Four measurements are recorded on every unit before it leaves the warehouse: insulation resistance, vibration and balance, efficiency with cosφ, and behaviour under load. On a continuously running efficient motor the vibration figure is the one that predicts bearing life, so a unit outside the band is held back rather than shipped.

Why DRG Motor?

The build is fixed: 100% pure copper windings, cast iron frame, IP55 protection, class F insulation, to IEC 60034 and EU Ecodesign. Copper cross-section is where an ultra-efficient design differs from a standard one, and it is also where a cheaper motor is usually thinner. Stock is held directly, so the price is not carrying a distributor step. For more about our range, see our industrial electric motors guide.

Frequently Asked Questions

What is the difference between single-phase and three-phase motors?

Single-phase motors run at 220 V with low power, three-phase motors at 380 V with high power. For industrial applications, three-phase motors are more efficient and suitable.

Which powers are held in the efficient range?

The efficient range runs across 0.55 kW to 355 kW in the standard speeds and mounting forms. For a specific duty point our team works back from the load curve and names one model rather than a bracket.
