Standard Electric Motors

Standard motors are among the most widely used and proven reliable solutions in industrial facilities. Thanks to their robust construction, stable performance, and wide range of applications, these motors operate smoothly across various machines and systems, making them an ideal choice for businesses seeking cost-effective solutions. With different power and speed options, standard motors deliver high efficiency and long-lasting performance in both crushing-screening plants and other industrial applications. Their durability and ease of maintenance make them stand out. DRG Motor’s standard motor range provides reliable solutions suitable for every need.

Key Features of Standard Electric Motors

  • Motor Type: Mostly three-phase squirrel-cage asynchronous motors (most common type).

  • Working Principle: Alternating current flows through the stator windings → generates a rotating magnetic field → induces current in the rotor → rotor turns.

  • Power Range: From 0.09 kW up to hundreds of kW or even MW levels.

  • Voltage: 220/380 V or 400/690 V (star–delta connection).

  • Speed: 750, 1000, 1500, 3000 rpm (depending on pole count).

  • Efficiency Class: IE3 (Premium Efficiency) is now standard; higher-efficiency IE4 and IE5 motors are also available.

Advantages of Standard Motors

  • Robust and reliable: Long service life, low maintenance needs.

  • Cost-effective: Low initial investment, spare parts easily available.

  • Versatile applications: Used in pumps, fans, compressors, conveyors, crushers across almost every industry.

  • Energy savings: IE3 efficiency provides significant electricity savings compared to older IE1–IE2 motors.

Applications

  • Industry: Crushing-screening plants, mills, press machines.

  • Energy: Pumps, fans, blowers, compressors.

  • Agriculture: Water pumps, feed mixers.

  • Construction: Cranes, crushers, concrete plants.

  • Residential/Small Applications: Single-phase versions for refrigerators, air conditioners, washing machines, etc.
