DC machines: Time-tested and user-friendly

DC machines show their strengths in numerous fields of application. Due to their high power density they are particularly compact and with their state-of-the-art equipment they fulfill every requirement in the areas of machine building and plant construction. DC machines supplied with power converters stand out due to their excellent control characteristics and a simple closed-loop control structure.

Additional advantages of DC machines are the high starting torque from standstill and the excellent smooth running characteristics down to the lowest speed. Also worth mentioning is the low noise level. Increased stress on the insulation as result of voltage peaks does not occur.
DC machines have a high level of electromagnetic compatibility. In the majority of cases, no additional measures are needed to reduce interference emission or to increase resistance to interference.

DC advantages at one glance:

• Easy of use
• High adjusting range from low to very high speed
• High dynamic with fast rate of current change
• Smooth running characteristics
• Less volume
• Energetic recovery to save energy
• Small maintenance effort
• High magnetic compatibility
