DC drive technology: Dynamic, rugged and cost effective

Depending on the application, DC drives are frequently the most favorably-priced drive solution. They have many advantages when it comes to reliability, operator friendliness and operating characteristics. Just as before, there are some good technical and economic reasons for still using DC drives in many industrial areas:

• Favorably-priced four-quadrant operation
• Continuous operation at a low speed
• Full torque and low torque ripple even at low speeds
• High starting torque
• High overload capability
• Wide speed control range with constant power
• Low space requirement and low weight
• Reliability

Main applications for DC drives include:

• Rolling mill drives
• Wire-drawing machines
• Extruders and kneaders
• Presses
• Elevators and cranes
• Cableways and lifts
• Mine hoists
• Test stand drives
