Description

The MHD095C-058-NG1-RN is a high-performance, permanent-magnet AC servo motor from Bosch Rexroth’s MHD series, engineered for precision motion control in demanding industrial automation applications. With a compact frame size (95 mm flange), integrated feedback, and optimized thermal design, this motor delivers high torque density, smooth low-speed operation, and dynamic responsiveness—ideal for CNC machining, robotics, packaging, printing, and material handling systems.

As part of Rexroth’s IndraDrive ecosystem, the MHD095C-058-NG1-RN seamlessly integrates with IndraDrive amplifiers and IndraWorks engineering software, enabling plug-and-play commissioning, real-time diagnostics, and advanced tuning for maximum machine throughput.

Application Scenarios

At an automotive component stamping facility in Germany, a high-speed transfer line required precise synchronization between six robotic arms and press actuators. Engineers selected the MHD095C-058-NG1-RN to drive the camless servo feeders due to its high overload capacity and smooth torque ripple (<2%). During peak production, the motor accelerated 45 kg tooling from 0 to 120 strokes/minute in under 0.8 seconds—repeatedly, 24/7—without overheating, thanks to its IP65-rated housing and efficient heat dissipation. Over two years, zero motor failures were recorded, reducing unplanned downtime by 35%. For manufacturers pushing the limits of speed and accuracy, the MHD095C-058-NG1-RN isn’t just a motor—it’s a performance multiplier. Parameter 表格 🔍 Decoding the Model Number: MHD: Motor High Dynamic 095: 95 mm flange size C: Long stack length (higher torque) 058: ～5.8 kW rated power NG1: Smooth shaft, no keyway, no brake RN: Resolver feedback Technical Principles and Innovative Values Innovation Point 1: High Torque Density with Low Cogging The MHD095C-058-NG1-RN uses optimized neodymium magnets and skewed stator slots to minimize cogging torque—enabling ultra-smooth motion at speeds as low as 1 rpm, critical for glass handling or optical alignment. Innovation Point 2: Robust Resolver for Harsh Environments Unlike optical encoders, the built-in resolver operates reliably in high-vibration, dusty, or humid conditions (e.g., foundries, washdown areas)—with no risk of lens fogging or glass fracture. Innovation Point 3: Direct Integration with IndraDrive Ecosystem Plug into any Rexroth IndraDrive amplifier (e.g., HCS02. HCS03), and the motor’s electronic nameplate (stored in resolver interface) auto-loads parameters—eliminating manual setup errors. Innovation Point 4: Thermal Efficiency Without External Cooling Despite 5.8 kW output, the motor relies solely on natural convection—reducing noise, maintenance, and footprint compared to fan-cooled alternatives. Application Cases and Industry Value In a pharmaceutical blister-packaging machine in Switzerland, the MHD095C-058-NG1-RN drives the indexing turret that positions tablets at 300 cycles/minute. Its low torque ripple ensures no product shifting during rapid starts/stops—achieving 99.98% fill accuracy. Meanwhile, a U.S. aerospace CNC router uses this motor on the Z-axis for titanium milling, where its 55.5 Nm peak torque handles sudden load changes during deep-pocket cutting without stalling. Across industries, the MHD095C-058-NG1-RN consistently enables higher machine speeds, longer component life, and lower total cost of ownership.

VAMAS Safety Module: Adds STO (Safe Torque Off) functionality when paired with compatible IndraDrive. Installation, Maintenance, and Full-Cycle Support Installation requires mounting the motor via its IEC B5 flange and connecting power and resolver cables using Rexroth-standard connectors (e.g., RKL series). Ensure proper grounding of the motor housing and shielded cables to minimize EMI. No lubrication or brush replacement is needed—the motor is maintenance-free for its entire service life (typically >20.000 hours).

During commissioning, connect to IndraWorks DS: the software reads the motor ID and loads optimal current/torque limits automatically. Use the built-in oscilloscope to monitor actual vs. commanded torque—useful for detecting mechanical binding or resonance.
