REXROTH MHD115C-058-PG1-BA Servo Motor

Description

n industrial automation landscapes where torque demands fluctuate wildly during rapid acceleration or heavy lifting, the Bosch Rexroth MHD115C-058-PG1-BA offers a dependable fix for engineers tired of motors that falter under peak loads or lose sync in multi-axis coordination. Think of a metal forming press where inconsistent holding during pauses risks misalignment and rework, or an injection molding machine where speed variations trigger quality dips—these issues arise from actuators that can’t balance power with precision feedback. This synchronous servo motor tackles them head-on by delivering robust, electronically commutated torque through its permanent magnet design, paired with a reliable multiturn encoder that feeds accurate position data back to controllers, keeping I/O signals crisp and process control loops locked in.

It’s indispensable in high-reliability setups like printing presses or assembly robotics, where continuous uptime hinges on motors that shrug off thermal spikes and vibration without skipping a beat. The Bosch Rexroth MHD115C-058-PG1-BA integrates effortlessly into modular systems, its integrated holding brake (rated at 70 Nm) securing loads during power-off states to prevent drift, while surface cooling handles heat dissipation for sustained performance in enclosed cabinets. For upgrades in legacy automation, it pairs with IndraDrive controllers without major overhauls, easing the shift to higher dynamics and reducing engineering tweaks for signal reliability. In process control environments pushing for faster cycles, this motor’s overload safeguards and grease-lubricated bearings minimize unplanned stops, letting you scale operations confidently while dodging the hidden costs of erratic motion in demanding industrial automation workflows.

When sizing up options for robust motion handling, the Bosch Rexroth MHD115C-058-PG1-BA proves its worth by prioritizing high torque density in a frame that’s versatile enough for tight footprints, ensuring your system stays agile without compromising on the stability needed for precise I/O architectures.

The Bosch Rexroth MHD115C-058-PG1-BA acts as a high-performance AC synchronous servo motor in the MHD series, residing at the execution tier of your motion control hierarchy. It transforms drive commands from IndraDrive-compatible controllers into rotational force via electronic commutation of its permanent magnet rotor, generating up to 70 Nm peak torque for dynamic start-stop sequences while the integrated 24-bit multiturn Hiperface encoder supplies absolute position feedback (up to 4096 turns) for closed-loop accuracy. This encoder communicates over EnDat or Hiperface protocols, syncing seamlessly with PLCs or safety modules to enable real-time adjustments in multi-axis setups.

Flange-mounted on a 180 mm diameter base per DIN 42948 standards, it drives loads via a plain shaft with sealing ring, feeding into backplane or distributed I/O systems where regenerative energy from braking can loop back via shared DC buses for efficiency. The built-in holding brake engages in 53 ms to secure vertical or suspended axes, with diagnostics tracking thermal and overload states to flag issues early, supporting redundancy through hot-plug configurations. In broader automation stacks, the Bosch Rexroth MHD115C-058-PG1-BA bridges field-level actuation with supervisory controls, leveraging its IP65-sealed housing to withstand dust or splashes while relaying health data upstream—fostering a resilient architecture that adapts to protocol shifts like Sercos or Profinet without downtime.

Deploying the Bosch Rexroth MHD115C-058-PG1-BA means gaining a motor tuned for unyielding dynamics, where its high torque-to-inertia ratio sustains 47 Nm continuous output across broad speed ranges, eliminating the velocity drops that slow production and inflate energy use in torque-intensive runs. This edge in performance consistency lets teams dial in tighter tolerances without constant retuning, preserving quality in high-precision tasks while the surface-cooled windings dissipate heat effectively to avoid derating in ambient-challenged spots.

Diagnostics take the guesswork out of upkeep, with encoder-stored parameters enabling rapid fault isolation that cuts troubleshooting time and extends mean time between failures—often by double digits in monitored fleets. Its modular fit with existing drive ecosystems trims integration hurdles, allowing parameter swaps via software for quick adaptations to process tweaks, which lightens the load on engineering during expansions or variants. Engineered for endurance, this motor upholds long-term performance against wear, recycling braking energy to trim power bills and ensuring your automation backbone remains robust through evolving demands.

In metalworking presses for automotive parts, the Bosch Rexroth MHD115C-058-PG1-BA actuates forming rams, where its peak torque handles heavy impacts under harsh, oily conditions, guaranteeing critical system uptime and cycle fidelity in 24/7 operations.

Printing and packaging lines deploy it for web tension control, meeting fast data cycles from encoders to sync rollers precisely amid dusty, high-vibration environments, boosting throughput in process control setups.

For injection molding in plastics manufacturing, this servo motor powers clamping mechanisms, delivering high reliability during rapid open-close sequences to minimize defects and support continuous uptime in temperature-variable facilities.

As you gear up to integrate the Bosch Rexroth MHD115C-058-PG1-BA, double-check the 180 mm flange’s centering ring tolerance at 0.05 mm max and align the shaft within 0.03 mm runout to safeguard bearing life from the start. Pair it strictly with IndraDrive controllers, verifying Hiperface protocol match via Rexroth’s IndraWorks software to sidestep comms glitches, and ensure surface temps stay under 100°C with adequate cabinet venting—add heat shields if vibrations exceed 10 g. Route power cables separately from feedback lines using shielded twists to fend off EMI in shared trays.

Maintenance stays straightforward: every quarter, eyeball the shaft seal for cracks or residue, particularly in oiled shops, and swab the cooling fins to sustain dissipation rates. Tap into the drive’s parameter viewer monthly to scan winding temps and brake coil resistance, flagging drifts that signal wear. An yearly dynamic load sim via test bench confirms torque curves hold true, and while no user-serviceable internals exist, syncing encoder data memory during installs cuts startup snags. This proactive cadence keeps interventions rare, aligning with your push for lean, uninterrupted automation.
