Frequently Asked Questions
How does the absence of a blocking/hydraulic brake impact safety and holding torque when the motor is powered off?
Without a blocking brake, the motor cannot resist external loads when unpowered; for vertical or gravity-influenced loads or safety positioning, an external brake or mechanical lock will be required.
What is the bearing load capability (radial and axial) of the MDD025 motors, and how must shafts or attachments be designed?
Radial and axial loads are limited per the MDD-025 class’ shaft load graphs; exceeding them drastically reduces bearing life. Attachments should minimize overhung loads and ensure balanced loading especially above low RPMs.
How does the centering diameter (40 mm) influence mechanical coupling and alignment in system design?
The 40 mm centering diameter helps in precise alignment with flanges or hubs, reducing eccentricity; proper alignment avoids vibrations and premature wear in the shaft bearings.
What are the electrical drive / winding characteristics (resistance, inductance, current) for the Bosch Rexroth MDD025B-N-100-N2G-040FE0, and how do they affect performance at high speed?
The MDD-025 “0.60 Nm at standstill / 10000 rpm” variant has winding resistance and inductance tailored to allow rapid current change; high speed performance depends on the drive’s ability to supply enough voltage to overcome winding inductance and back EMF.
What are the implications of having a standard housing and natural convection cooling on duty cycle?
Natural convection limits continuous power output when ambient temperature is high, and requires that heat be dissipated via the housing; heavy duty or high ambient scenarios may demand slowed speed or intermittent operation.
