Industrial Electric Motors — DRG Motor

Yes. DRG Motor products provide significant energy savings by being manufactured in the IE3, IE4 and IE5 high-efficiency classes. A high-efficiency motor lowers the electricity bill by doing the same work with less electricity.

Especially in industrial motors running 24/7, even a few-point increase in efficiency turns into significant annual savings. For this reason, high-efficiency motors pay back their initial cost in a short time and provide substantial gains in the long term.

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.

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.

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.

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.

Overheating is prevented by correctly sized motor selection, adequate ventilation, regular maintenance and suitable operating conditions. Overloading the motor, low voltage, a blocked fan cover or insufficient cooling are the main causes of overheating.

DRG Motor's F insulation-class and IP55-protected motors offer high temperature resistance. In critical applications, the use of thermal protection (PTC thermistor) and a frequency inverter additionally protects the motor against overheating.

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.

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.

DRG Motor products are used across a very wide range of sectors, including mining, construction, stone crushing and screening plants, manufacturing, pump and fan systems, food, textiles, ventilation and automation. Our wide power range from 0.55 kW to 355 kW offers a suitable solution for almost every industrial application.

We supply dedicated solutions for different applications, from general-purpose industrial motors to crusher, vibration and smoke extraction motors.
