Control
The contact force can be indirectly measured using the readable current value of the motor spindle. In addition, speed monitoring offers the advantage of detecting changes in process behaviour at an early stage.

MD Drive
Compact frequency converter with intelligent evaluation
The MD Drive from Mannesmann Demag combines a brushless DC motor (BLDC) with an integrated frequency converter in a particularly compact housing. This space-saving design allows direct mounting on tools, robot arms or in production cells.
Precise control and reliable monitoring
In addition to precise speed control, the MD Drive ensures a constant speed curve, which is essential for reproducible machining results in brushing, grinding and polishing processes. Furthermore, both current and speed data can be read out and evaluated in real time.
Intelligent evaluation of current and speed data
- Current value: Since the motor current is proportional to the mechanical load and the contact force, the evaluation of the current value provides indirect, contactless monitoring of the tool load.
- Speed: The evaluation of the speed also enables the detection of process deviations, e.g. due to changed load situations or mechanical problems.
The combination of both measured variables provides a comprehensive picture of the machining process with the following advantages:
- Early detection of tool wear and component deviations
- Quality assurance through stable process parameters
- Prevention of unplanned downtime through early warnings
- Reduced need for additional sensors – the system uses existing motor parameters for process control
Overview of the advantages:
- Compact frequency converter for our BME motors for brush applications
- Space-saving installation and easy integration
- Precise and constant speed control
- Real-time evaluation of current and speed data
- Indirect monitoring of contact pressure and tool load
- Higher process reliability and quality control
- Low maintenance, low noise and energy efficient
- Made in Germany – reliable quality and short delivery times
