Frequently Asked Questions

What is the rated peak current for the Bosch Rexroth Indramat MHD112A-024-NP1-AN motor under standard operational environment?

The peak current is specified at 59 A, enabling short-term torque surges without overstressing windings, provided cooling integrity and electronic drive parameters are controlled.

Where is the encoder system integrated in the Bosch Rexroth Indramat MHD112A-024-NP1-AN motor, and how is feedback provided?

A digital servo feedback encoder is mounted on the rear flange, providing relative position signals directly to the drive controller for motion precision and velocity regulation.

Does the Bosch Rexroth Indramat MHD112A-024-NP1-AN motor provide shaft sealing protection against external contaminants?

Yes, a dedicated shaft seal ensures ingress protection against industrial dust and fluid contaminants, extending bearing lifespan and preserving dynamic efficiency.

What structural role does the 192 mm flange size provide in the Bosch Rexroth Indramat MHD112A-024-NP1-AN motor’s housing?

The flange size provides standardized mounting geometry, ensuring compatibility with heavy industrial actuators and enhancing load-bearing rigidity.

Does the Bosch Rexroth Indramat MHD112A-024-NP1-AN motor allow relative position detection without battery-based absolute referencing?

Yes, it uses relative position feedback, requiring homing procedures after power cycles, simplifying encoder structure but necessitating axis re-referencing.
