Industrial Electric Motors — DRG Motor

The main advantages of asynchronous (induction) motors are their robust structure, long life, low maintenance need and high efficiency. Since they contain no wearing parts such as brushes or commutators, they operate reliably under demanding industrial conditions.

A wide power range, easy availability and economical operating cost make asynchronous motors the most common choice for industrial and plant applications. These motors form the basis of DRG Motor's product range.

The main criteria to consider when choosing an electric motor are the application area, required power (kW), speed (rpm), energy-efficiency class (IE3/IE4/IE5), mounting type (B3/B5/B35), protection class (IP) and the conditions of the operating environment.

A correctly selected motor provides energy savings, long life and uninterrupted operation. The DRG Motor technical team helps you make the most accurate choice in terms of both performance and cost by determining the most suitable motor for your application.

Maintenance intervals depend on the motor type, power and operating conditions. In general, bearing lubrication, checking electrical connections and the terminal box, body cleaning and vibration monitoring should be carried out every 6–12 months. In dusty, humid or high-temperature environments, this interval should be shortened.

Regular maintenance extends motor life and prevents unexpected stoppages. High-efficiency, quality motors require less maintenance, lowering the total cost of ownership.

Motor power (kW) is determined by the load requirement of the machine to be driven; the motor should be selected close to but not below the load. Speed (rpm) is related to the number of poles: 2 poles ~3000 rpm, 4 poles ~1500 rpm, 6 poles ~1000 rpm.

An incorrectly selected motor can cause efficiency loss, overheating and early failure. For the correct power and speed calculation, sharing your application with our technical team allows us to find the most suitable solution.

IE (International Efficiency) classes indicate a motor's energy-efficiency level according to the IEC 60034-30 standard. IE4 means "super premium" and IE5 "ultra premium" efficiency; IE5 is the highest efficiency class currently available.

A higher IE class means the motor does the same work with less electricity. This reduces operating costs, lowers the carbon footprint and ensures compliance with European Union Ecodesign regulations. DRG Motor supplies high-efficiency motors from IE3 to IE5.

Motor efficiency is improved through correct sizing, the use of high-efficiency (IE3/IE4/IE5) motors, regular maintenance and suitable drive systems. Running the motor close to its rated load is more efficient than using an oversized motor.

In applications requiring variable load, using a frequency inverter (drive) prevents unnecessary energy consumption. Replacing old, low-efficiency motors with IE-class motors provides savings that pay for themselves in a short time.

In stone crushing and screening plants, motor selection is based on the crusher's capacity, the hardness of the processed material and the need for continuous 24/7 operation. In these applications, high starting torque, resistance to impact and vibration, and a robust body structure are critically important.

DRG Motor's cast iron-bodied, IP55-protected and F insulation-class motors are designed to withstand the demanding conditions of crusher applications. You can get support from our technical team for the right power (kW) and speed (RPM) selection.

Well-manufactured and regularly maintained electric motors generally operate trouble-free for 15–20 years or even longer. Motor life is determined by the insulation class, bearing quality, operating temperature, load conditions and maintenance routine.

DRG Motor's motors, with their F insulation class, quality bearings and high efficiency, are designed for long life. When used without overloading, in a suitable environment and with regular maintenance, the motors more than meet their expected service life.

Electric motors are basically divided into four main groups: AC motors, DC motors, synchronous motors and asynchronous motors. AC (alternating current) motors are durable, long-lasting and low-maintenance; they are widely used in pump, fan and general industrial applications. DC (direct current) motors are preferred in applications requiring precise speed control.

Synchronous motors run at constant speed and offer high efficiency; asynchronous (induction) motors, with their robust structure and economical operation, are the most common motor type in industry. The DRG Motor range mainly consists of high-efficiency three-phase asynchronous motors.
